China is entering a new era with its economy turning to quality development from rapid growth. JJJ, as a new capital economic zone, plays a key role in demonstrating city cluster’s quality development. This paper, aiming at JJJ’s coalition in developing strategy for a quality city cluster’s quality development, this paper, based on JJJ"s 13 perfectures’ 2011 to 2020 data, uses the contents of quality development to establish a comprehensive evaluation index system for JJJ city cluster’s quality development, and employs entropy-TOPSIS model to estimate JJJ city cluster’s 2011 to 2020 quality developing index, and applies coupling coordination model & spatial autocorrelation model to study its coupling coordinating level, temporal-spatial evolutionary trend and spatial concentrating effect.The coupling coordination of JJJ city cluster’s quality development shows a weak-then-strong trend, with major cities in coordination in 2011 to 2015 changing to developing cities, at a decreasing coupling coordination, but rising after 2015. The coupling has been steadily rising, 84% of JJJ’s cities are rising in their coupling, most with strong correlation among economy, eco-environment, innovation, and civilian welfare. Temporal-spatial pattern of coordination has not changed, Cangzhou, Tianjin, Tangshan and Qinhuangdao have always been at the tier 2 except Beijing seats atop. Spatial evolutionary pattern of quality development suggests Beijing, Tianjin and Langfang are in the core area of city cluster’s quality development, radiating outward to southeast, falling toward northeast. Economy, eco-environment innovation and civilian welfare are the same. JJJ’s city cluster’s quality development has a positive overall auto-correlation, cities of high quality development are geographically closer, with outstanding spatial heterogeneity, their capitals are mainly located in the promoting area, Cangzhou, Hengshui and Qinhuangdao in the transition zone, and Langfang in the radiation zone, negatively correlated. A key mission for JJJ’s city cluster’s quality development is to make up the regional developing gap. This paper presents suggestions on accelerating industrial transformation to diminish regional gap, intensifying environmental cooperation to promote green development, activating regional resources to drive innovation, and jointly constructing public services to share the dividends.

This paper, based on 2015—2019 panel data of China's 163 listed new energy companies, uses fixed effect model to study the impacts of governmental subsidies on operating performance of new energy companies, and discusses the adjustment of governmental subsidies on commercial operating performance under enterprises life circle, and uses grouped regression to check the effect of governmental subsidies on commercial operating performance amid different ownerships and marketization. Results show an upside-down U-shaped relation between governmental subsidies and commercial operating performance in new energy industry, outstandingly for growing companies, private companies, and in highly-marketized regions. Property ownership exerts a large adjustment.

As China's economic structure is being adjusted, resources based cities transformation has become a significant part of China's economic sustainable development, in which transformation policy plays a key role in transformation speed, direction and size. This paper uses policy tool classification, coding and frequency statistics to quantitatively analyze 47 pieces of transformation policies regarding resources\|based cities in China by means of PMC model. All levels of policy tools are of structural imbalance with governmental preference for environmental policy tools. Policy tools use is inconsistent, with policy supervision and evaluation missing. PMC index of 47 pieces of policies are qualified, but some get low scores in a few evaluation variables. Balancing policy tool structures and multiple-dimensional evaluation of policies may promote the transformation of resources based cities.

This paper, based on panel data of 16 cities of 2007, 2012 and 2017 in Shandong province, establishes a coordination model of population-economy-environment based on entropy and physical coupling model, which is used to study the temporal-spatial evolution of population-economy-environment system coupling coordination and to estimate their spatial Moran's indexes, and presents suggestions for Shandong's future development. Among 16 cities in Shandong province, their coupling coordination is improving thanks to a rising comprehensive development. The western inland is far behind the eastern and central in economy and population. A low spatial autocorrelation exists in their economy-population-environment development, but weakly positive between comprehensive development and coordination. Regional coordinated potential needs to be further developed.

This paper uses the three industries data and input & output model to analyze the overall industrial structure level and industrial correlation in Xinjiang, and finds out that Xinjiang is positioning at the para-industrialization stage led by the second industry, with a good developing trend, gaining some achievements in industrial structural adjustment. Issues are marked by irrational developing direction of the three industries that the first industry has a poor basis, easily subject to other industries, the second industry is still high-energy-consuming, high-pollution, low-technology without supports by high-technical industries, the third industry is lagging with low technicians. This paper presents suggestions on boosting the first industry, adjusting the second industrial structure, and developing the potential of the third industry, aiming at optimizing the third industrial structure and realizing long-term stable economic development in Xinjiang. 

This paper, based on Yili river valley's industrial development, discusses the path selection of its tertiary industries, and uses industrial linkage measurement model to evaluate the linkage effect among the first, second and third industries. The absolute linkage extent between the first and the third industries is far above the firstsecond and secondthird industries. The relative linkage extent in the secondthird industries has a rising trend except the firstsecond and firstthird industries. The overall linkage in the firstthird industries is far above the firstsecond and secondthird industries. This paper presents six modes and paths for industrial linkage development, and gives suggestions in promoting a bigger linkage effect among the tertiary industries in Yili river valley from industrial planning, industrial structure adjustment, and infrastructure optimization.

This paper classifies mines with mining rights into constructing mine, producing mine and residual mine. Mining right assessment on constructing mines is focused on recoverable reserve and investment validation, and that on producing mines is on remaining recoverable reserve and depreciation validation on gallery and ground construction, and that on residual mines is on reserve balance, remaining recoverable reserve, new resource estimation, and depreciation on gallery and ground construction. The residual mines deserve investment, including those ore remained which are difficult in mining and processing, of potential in finding new resources located in favorable mineralization zones. The overseas investment bears risks in exchange ratio, reserve, security and costs, which need serious evaluation before investing.

This paper, based on a brief introduction to the geography, geology and water resources in inland basins in Northwest China, gives a summary of issues in developing the groundwater resources, and analyzes the impact to the ecological environment. The unconscionable development and lowly-efficient utilization is one of the four key causes. This paper presents a strategy to develop the water resources in inland basins and to protect the ecological environment: to set up an scientific idea to develop the water resources and to protect the ecological environment; to optimize the drainage works investment policies so as to boost a rational development of water resources; to develop the groundwater in the middle-stream by making full use of underground reservoirs and to limit the development in the down-stream area; and to reinforce the land consolidation so as to decrease the water quantity of agricultural irritation.
