China’s natural resources administration system has provide a vital guarantee for natural resources use and protection over the past decades as a booster to ecological civilization construction, but it still has shortages in lack of rights and responsibilities and in overlapping of leadership and management, leading to lots of issues in unclear ownership subject of natural resources, fuzzy boundary of right confirmation and insufficient protection of property rights. This paper uses property rights theory to analyze the evolution of China’s natural resources administration system under guideline of “the 14th Five-Year Plan”and “2035 Outlook”, establishes a research framework of “system evolution-issues discussion-approach optimization”, and applies Pigovian tax, Coase Theorem, and new system economics theory to qualitative analysis of the natural resources assets property rights system optimization direction. Its evolution of natural resources administration system shows a clarifying ownership at a trend of separation of ownership and using right. Governments as the administrator of market shall uses power to mark market limit and make marketing rules. System performance is mainly related to the gaming between governments and markets, which may be promoted by optimizing the property rights system of “affiliation-rights & responsibilities-protection-transfer-supervision”. The research concludes that in order to improve the natural resources assets property rights system in our country, we should clarify the property rights, and realize the property rights in the legal subject clearly relying on the regulatory effect of the classification agent system. The content of registration and accounting should be clarified, and the information management platform of natural resources assets should be built to accurately grasp the assets, and use the ecological protection compensation mechanism to support the protection system, strengthen the intensity of protection, guarantee market transactions. Marketized trading platform shall be used to improve the allocating efficiency of natural resources, to transfer asset stock to asset increment. Supervision system shall be improved in all process which limits governmental power lists to avoid governmental monopoly.

China’s economy is shifting from rapid growth to quality development, causing China’s gold industry to shift away from the previous extensive development pattern based on scale and speed. In this paper, we developed a method for conducting a one-year quantitative material flow analysis in China’s mainland for 2019, based on statistical data and previous studies, for a better understanding of the current situation in the social-economic metabolism of gold. The funding allows us to gain a better understanding of the domestic gold cycle, which includes production, fabrication and manufacturing, use, and waste management. According to the findings, 1 015t of refined gold flowed from the production stage to the fabrication and manufacturing stage, with 900t lost as tailings and slag. In the fabrication and manufacturing stage, 781t of gold is imported, 1 706t of fined gold entered into the use stage, and 90t of gold dissipated. China’s gold supply suffered a high external dependence of 52.5% in 2019. In the use stage, total gold demand was 1 641t, of which consumption was 1 003t. Gold jewelry accounted for 67.4% of the consumption. At the waste management stage, China recovered 465t of refined gold in 2019, making up for 27% of the total supply. China’s gold production primarily relies on mining, secondarily on metallurgical byproducts, which was rising up to 16% in 2019 from 9% in 2000, indicating that the domestic gold industry’s intensity is gradually improving. China has had a great demand and high external dependence on gold. In recent years, China’s industrial gold consumption has increased rapidly. Domestic gold demand will continue to rise as the electronic industry develops. Recycled gold accounts for a significant portion of domestic gold supply, particularly golden jewelry recycling, which has greater economic benefits than industrial gold recycling, which requires further technological and industrial chain enhancement.

As an agricultural giant, China’s surging needs of phosphorous fertilizer to guarantee its crop security leads to mass of the industrial solid waste phosphogypsum during production of phosphorous acid and fertilizer, which harms the environment if dumping in the long term. China began to vigorously promote the resource utilization of phosphogypsum in 2018, and formulated and issued a number of encouraging policies. However, the comprehensive utilization rate of phosphogypsum is still low up to now, and the resource utilization market still needs to be continuously constructed and improved. In this paper, based on the problem of unclear production quantity of phosphogypsum in China, the product/waste coefficient method was used to estimate the output of phosphogypsum in China from 1957 to 2019 based on the output of phosphogypsum in “China Industrial Statistical Yearbook”, after field investigation and analysis in Yunnan, Guizhou, Sichuan, Hubei, Anhui and other provinces, Guizhou province, which has a good comprehensive performance in the utilization of phosphogypsum resources, was selected as the key research object, the material flow analysis was carried out, and the material metabolism graph of phosphogypsum resource utilization was drawn. Temporally,  Guizhou has a rising resource utilization trend of phosphogypsum with a utilization ratio at 58.80% in 2018 to 107.37% in 2020, marking a start point for Guizhou uses the historically-dumping phosphogypsum solid waste. As for the resource utilization means, Guizhou consumes phosphogypsum up to 964.5kt, 360.4kt, 330.9kt and 234.8kt from underground backfilling, acid making and other chemical utilization, construction materials and cement retardant in the first quarter of 2021, with a comprehensive use rate up to 55.02%, still at the preliminary use stage of low added-values and small scale. This paper, based on site investigation, studies the material metabolism rule of phosphogypsum in the whole life cycle from production to resource utilization, and reveals the key issues in its raw materials, technology, products and policies, and from the perspective of government, enterprises, consumers and other stakeholders, targeted policy suggestions are put forward, hoping to provide scientific theoretical basis for the accurate management and resource utilization of phosphogypsum in China, also provides a scientific reference for controlling other mass solid wastes under the background of circular economy, zero-waste cities and carbon reduction.

As uncertain risks are rising in global politics and economy, anti-globalization which is harmful for industrial security and stability begin to arise. To discuss if China’s energy trade cooperation with “the Belt and Road” nations can offset the adverse impacts of anti-globalization and deeply analyze the role of international energy cooperation on the energy security of participating countries and regions and the underlying impact mechanism. This paper attempts to uses Tobit model and basic regression model to study the impacts of China’s energy trade cooperation with “the Belt and Road” nations on energy security during 2000 to 2020 under “the Blet and Road Proposal” from energy consumption and production with robustness tested. Results show China can guarantee itself energy consumption security and energy production security under China’s energy trades with “the Belt and Road” nations. Increasing the total energy trade between China and “the Belt and Road” nations can improve the energy consumption security level of these nations by reducing the energy use costs of cooperative energy consuming nations. Also can improve the energy production security level of these nations by promoting economic growth of cooperative energy producing nations. Constrained by the geographic location, the positive effect of energy trade cooperation between China and Asian countries along  “the Belt and Road” is more significant than that of other regions. This paper concludes that China’s energy trade with “the Belt and Road” nations can positively promote their economic sustainability, guarantee energy security and reach a mutual bloom. In order to maintain the energy security of China and  “the Belt and Road” nations, we should constantly expand and deepen the energy cooperation between  “the Belt and Road” nations, promote the diversification of energy trade, continue to optimize the international cooperation environment, and create good external conditions for international energy trade. To resist the security threats posed by various external adverse factors to China’s participation in international energy trade, China should constantly enhance its comprehensive strength to ensure the safety and smoothness of international energy transport channels. For a sustainable energy development, China shall boost its’ international cooperation with “the Belt and Road” nations on clean and new energies and reform their energy production and consumption ways.

Guangdong province has surging demand for energy consumption as it speeds up its industrialization and new urbanization, leaving key points on how to adjust provincial energy consumption structure, boost intensive and clean use of energy and decrease carbon emission as Guangdong’s responses to “Dual Carbon Strategy”. This paper analyzes the dynamic changes of energy consumption in each sectors in Guangdong province from multiple perspectives,  explores their ecological relations of sectors in energy consumption networks,  and presents scientific theoretical basis and policy recommendations for Guangdong to make differentiated energy saving consumption reducing policies regarding its “Five-in-One” overall layout. By collecting the input-output tables and energy consumption lists of Guangdong province in 2007, 2012 and 2017, this paper relies on input-output theory and ecological network analysis. By constructing an input-output ecological network model, the direct and indirect energy consumption of 26 sectors in the social and economic system of Guangdong, the energy flow among the sectors and the ecological relationship among the sectors were quantitatively analyzed and evaluated. From the perspective of direct energy consumption, transportation, warehousing, and postal industry(S24)and manufacture of metal smelting and rolling processing(S13)are key industries that policy makers need to pay special attention to, while indirect energy consumption caused by heavy industries such as chemical industry(S11)and manufacture of nonmetal mineral products(S12)cannot be ignored. A strong correlation exists between construction(S23)and manufacture of nonmetal mineral products(S12)with a coexisting index less than 1 in energy consumption system, suggesting a sub-healthy system. A strong control and reliance is displayed between the secondary and the tertiary industries, which needs a coordinated development while encouraging industrial transformation. This paper presents suggestions for Guangdong on executing energy saving consumption reducing approaches both in production and consumption sides, and increasing the utilization rate of inter-medium products and developing recycling economy. A trans-sector cooperative energy saving system is proposed to promote a shift in energy saving consumption reducing from single sector to multiple sectors.

China is focusing on green economic transformation and industrial structure upgrading, how to pay attention to the relationship among environmental regulation, green innovation and industrial structure, in order to obtain the triple bonus of environmental protection, green technological innovation and industrial structure upgrading, has become one of the important issues in Chinese academic circle nowadays. This paper, based on 2003 to 2019 provincial panel data of China’s 30 provinces, autonomous regions and municipalities, uses spatial Dubin model to compare the impacts of environmental regulation and green innovation on industrial structure upgrading under three weight matrixes, and to measure the direct, indirect and gross effects of the main explanatory variables, and empirically tests whether environmental regulation and green innovation promote industrial structure upgrading in eastern, central and western regions of China. Generally, environmental regulation and green innovation promote rationalization and upgrading of industrial structure under three spatial weight matrixes, increase by 1% of environmental regulation intensity at geographical distance matrix will lead to an increase by 0 065% in upgrading of industrial structure. The influence of green innovation on the upgrading of industrial structure is most significant in the geographical distance matrix, with the influence coefficient reaching 0 066. Viewing from overflowing effect, upgrading of industrial structure can be directly contributed by environmental regulation at geographic distance matrix, and indirectly by green innovation through spatial overflowing effect. In regional heterogeneity, environmental regulation promotes the upgrading of industrial structure most in the western, but little in the central and eastern, green innovation plays a positive role in a developing trend of in western more than central and in central more than eastern. It concludes China shall strive to improve green innovative abilities and urbanization, and promote industrial transformation of high pollution enterprises, increase environmental regulation intensity and make differentiated regional policies to prevent industrial transfer of pollution asylum effect, which is of significance in boosting China’s industrial structure upgrading and reaching a quality and green economic development.

Green innovation marks the high-tech industries under green development background, which needs governmental supports. Disagreement exists in the research of the relation between governmental supports and green innovative efficient, and insufficient studies on regional differences and mechanism. This paper, based on China’s provincial panel data of high-tech industries, uses DEA model to measure their 2009 to 2020 green innovative efficiencies of China’s 28 provinces, autonomous regions and municipalities, and applies the Global Moran’s Index to check the spatial autocorrelation of the green innovative efficiency of high-tech industries. Mixed fixed effects spatial lag model is employed to analyze the impacts of governmental supports on high-tech’s green innovative efficiencies, and the robustness test is carried out using the method of variable replacement. The regression analysis on the impacts of government supports on green innovation efficiency of high-tech industries has been carried out in the eastern, central and western regions of China to assess internal mechanism of governmental supports. China’s average values of green innovative efficiency of high-tech industries has risen to 0.611 from 0.511 during 2009 to 2020, with eastern higher the national average, and central and western lower. According to the Moran index test, the green innovation efficiency of China’s high-tech industry shows strong positive spatial correlation under the spatial weight matrix from 2009 to 2020. Governmental supports show an outstanding inverted U-shaped relation with green innovative efficiency of high-tech industries, which is positively contributed by environmental regulations, economic performance and foreign direct investment. Impacts of governmental supports vary with eastern, central and western. Governmental supports cast a directive role on green innovative efficiency, displaying an obvious inverted U-shaped relation with enterprises’ research & development investments. This paper presents suggestions that governments make appropriate subsidy range according to high-tech’s actual situation, with supportive policies varying with regions, industries and eco-environments.

In order to construct a green innovative system oriented by governments, operated by enterprises and public involved, all levels of governments issue series of supportive policies via governmental allowance in powering green innovation. It has been an important research topic to study the impacts of governmental allowance on green innovation, and to maintain it as a long-term drive. This paper clarifies the relation between governmental allowance and green innovation, selects 864 Chinese A-share listed companies in Shanghai and Shenzhen from 2016 to 2020 as the research sample, uses “resources-ability-action” model to incorporate the enterprise’s ESG performance into the analysis framework of governmental allowance and green innovation, explore the impacting mechanism of governmental allowance on green innovation from the perspective of enterprise’s ESG performance, verified by fixed effect model. The results show that governmental allowance have a significant positive impact on green innovation and can directly promote the green innovation of enterprises. Governmental allowance also plays an outstandingly positive role on enterprises’ ESG, encouraging enterprises to care about environmental protection,  to fulfil social responsibilities and to increase governance performance. Enterprises’ ESG plays a partial intermediary role between governmental allowance and green innovation. Governmental allowance can impact enterprises’ green innovation through their ESG in environmental responsibilities and governance performance, but enterprises’ social responsibilities do not play a media role between governmental allowance and green innovation. Compared with a lower ESG level, governmental allowance plays a stronger role in enterprises’ green innovation under a higher ESG level. Governments shall manoeuver allowance to reach a high-quality green development, which requires governments enlarge allowance in an appropriate way to improve ESG. Use of such allowance shall be under strict supervision through a sound ESG evaluation system. Governmental allowance is suggested to be differentiated based on enterprises’ ESG levels to increase the use efficiency of governmental allowance.

Yangtze River Economic Belt is the most active and economically most dense stream belt in China. China’s fast growing economy and urbanization results in water resources consumption and environmental pollution with an aftermath of low water resources green efficiency in this economic belt. This paper, based on provincial and municipal spatial scales and data of 9 provinces and 2 municipalities in the Yangtze River Economic Belt, uses non expected output ultra-efficiency SBM model to estimate its water resources green efficiency, and establishes a spatial Dubin model to study the impact of water conservancy construction investment on water resources green efficiency. The results show an overall low efficiency, most provinces/municipalities under the effective level. Temporally, the water resources green efficiency shows a fluctuated rising trend, characterized by “downstream>upstream>middle stream”. Spatially, it shows a “eastern high west low and northern high southern low” pattern, most provinces/municipalities in a transiting stage up to the medium green efficiency. Water conservancy construction investment largely improves the water resources green efficiency within the provincial/municipal ranges, with little influence on their neighboring areas. Among control variables, economic development level and industrial structure positively exert boost the water resources green efficiency, but urbanization level, water resources abundance and pollution play adversely, and knowledge level has no significant effect on the green efficiency of water resources. To promote the positive impact of water conservancy construction investment on water resources green efficiency in the Yangtze River Economic Belt, this paper presents suggestions for governments on holding of green development concept, combining water resources comprehensive governance with economic development, carry out green efficiency management of water resources in the Yangtze River Economic Belt according to local conditions, and diminishing its provincial variance for a coordinated and sustainable development on society, economy and ecology in the Yangtze River Economic Belt.

China’s rapid economic growth leads to environmental pollution since its openness 4 decades ago, of which waste water becomes a pressure on China’s ecological civilization. This paper, based on China’s 100 eastern cities’annual panel data, uses two-way fixed effects semiparametric variable coefficient model with different smooth variables and STIRPAT model to study the connection between industrial waste water discharge and GDP per capita, expenditure on local financial science undertakings, and number of industrial enterprises above designated size in eastern China. Economic growth has a positive U-shaped relation with industrial waste water discharge. The marginal impacting indicator of GDP per capita on industrial waste water discharge is -0.397 0 when the logarithm value of GDP per capita is 2.290 4, reaching the lowest point of the U-curve. The marginal impacting of the proportion of the secondary industry displays a non-linear U-shaped relation on industrial waste water discharge with expenditure on local financial science undertakings rises, first down and up. The marginal impacting of population density on industrial waste water discharge also shows a non-linear fluctuated rising U-shaped trend, first falling and then slightly rising with number of industrial enterprises above designated size are increasing. The marginal impacting indicator of the secondary industrial proportion on industrial waste water discharge is 0.683 3 when the logarithm value of expenditure on local financial science undertakings is 7.648 6. When the logarithm value of number of industrial enterprises above designated size is 5.315 5, the marginal impacting indicator of population density on industrial waste water discharge is -0.061 9, and both marginal impact values are the lowest points of the curve. It concludes that economic growth and expenditure on local financial science undertakings promote the industrial waste water discharge, the number of industrial enterprises above the designated size has the effect of inhibiting industrial waste water discharge first and then promoting it. The mean value of marginal impact is negative in the early stage, but with the increase of the number of industrial enterprises above the designated size, there will be an increasing trend from negative to positive. When the expenditure on local financial science undertakings increases by 1%, industrial waste water discharge will increase by 0.72% through the proportion of the secondary industry. When the number of industrial enterprises above the designated size increases by 1%, the industrial waste water discharge will decrease by about 0 013% in the early stage through the population density, but in the later stage, with the increase of the number of industrial enterprises above the designated size, the industrial waste water discharge will also increase gradually through the population density.

Ecological restoration is a way to comprehensively restore damaged environment with premium results at minimum costs. As China’s society and economy develop rapidly, the conventional restoration of “who made who restore”is low in efficiency, and below the objectives. To reach a quality ecological restoration, it is a good practice to approach in marketized way under guidelines of governments, which can fully fulfill the determination of markets in resource allocation, focus on key ecological domains, power the markets, maintain nation’s ecological security and push construction of “Beautiful China”. This paper establishes an evolutionary game model between government and ecological destruction enterprise with attention on both ecological and economic benefits, which is used to deeply explore the inevitable relation and evolutionary rules between government made ecological restoration objectives and marketized ecological restoration development, and discuss the factors, and uses data evolutionary simulation to validate the model. Key factors in the evolutionary game model include supervision costs in ecological restoration objectives, scale economic extent to be reached in professional restoration, and economic benefits. It concludes that governments can effectively boost the marketized development of ecological restoration by making high standards of ecological restoration objectives in developed areas. The government chooses a concise and clear way of ecological supervision and employs professional ecological assessment agencies to conduct ecological restoration assessment, which can decrease the supervision costs and increase the supervision efficiency, all favorable for a marketized ecological restoration development. Professionally ecological restoration enterprises shall intensify their green innovative abilities to minimize the restoration costs to realize scale economic benefits with gaining both restoration achievement and expected economic returns, further to reach a quality coordinated development of economic society and ecology.

Development in mining cities will result in lots of economic, social and ecological issues in environment and land use layout. For a green development of mining cities to promote a harmonious coexistence between human and nature, land use changes in mining cities need to be studied in its driving mechanism, which can provide a theoretical basis for boosting a quality sustainable development in mining cities. This paper, based on a case study in Guixi city, Jiangxi province, uses land use migration matrix and scenic pattern index to study its 1990 to 2018 land use structural changes. On the basis of 2010 land use situation, this paper applies CLUE-S model to study its 2030 land use pattern under three scenarios and compares the results. Guixi’s land use changes are mainly on the shift from farmland and forest land to mining land during 1990 to 2018, with reduced areas 15.75km² and 32.18km² respectively, and mining land increased by 41 54km², others remain little change. During 2000 to 2010, mining land use largely increased from 1 09km² to 25.01km². During 1990 to 2018, scenic patch of Guixi’s land use has an increase by 74, patch density increase by 0.03 count/km², morphology index increase by 1.44, Shannon diversity index increase by 0.08. The global scenic pattern shows a fragmented and small sized, and diversified, with rising disorder in farmland, forest and grass land uses, and water, construction, mining land uses showing an increasing combination and agglomeration on a simply intensive patch. The simulated results, under three scenarios, natural development, ecological protection and rapid development, Guixi’s farmland is continuously decreasing, the area of construction and mining land has increased. The ecological protection scenario is more consistent with the Guixi’s urban planning and development. Guixi shall clarify the land functionalities with focusing on appropriate land use structure, mitigate land use conflicts, and increase land use efficiencies. This paper presents suggestions on reclamation, separating mining areas, green development on mining land uses, and boosting industrial transformation, of significant for Guixi to reach a sustainable development of ecological environment and mineral resources and to be the title holder of green copper capital.

This paper aims at studying the structural evolution of urban construction land and its mechanism and at allocating appropriate construction land, and presents theoretical supports and policy suggestions for the Three Northeastern Provinces to make urban land planning. Urban construction land is divided into Category R (residential), Category M (logistic warehouse and industrial), Category C (public management and public services, commercial service, public infrastructure), Category S (road, green land and square land) according to “Urban Construction Statistics Yearly”. Information entropy and shift-share analysis are employed to study their construction land structural evolution in 34 Northeastern cities by means of GIS spatial analysis. Since 2002, their construction land size has been rising at a annual rate 4.14%,  most contributed by Categories C and S with increasement by 3.29% and 5.51%, respectively compared with 2002. Category R has a least increment among the four categories at a falling trend. Cities with shift effect positively adjusting role on share effect Categories M, C and S have significantly increased in counts, suggesting a rationalizing urban construction land structure in the Northeastern cities. Their construction land structure has had little change with a relatively stability in their proportions among the four categories since 2012. Improvements in industrial structural, urban transportation and urban residential conditions plays a strong role on construction land structural evolution in the Northeastern cities. Appropriate urban construction land structure may boost urban functionalities. Fulfilling comprehensive use efficiency of urban construction land can intensify a modern urban construction. This paper presents suggestions on making appropriate land use policies with priority on land types with growing advantages, diminishing excessive land types and activating the land stock for more rationalized construction land structure in the Northeastern cities.
