This paper studies the market demands of Floating Production Storage and Offloading (FPSO), presents a way to forecast the global FPSO market demands. By means of a method integrated with entropy, artificial neural network, random forest regression, ADABOOST regression, and ARMA model, this paper forecasts the global FPSO orders with the results showing that FPSO needs 9 ships in 2025, 10 in 2030 and 12 in 2035, suggesting a stable rising global FPSO market demand in the future ten years. China's ship manufacturers should pay close attention on the impacts of crude oil price on FPSO market demands and use new technologies in reducing carbon emission and increasing market shares.

Under extreme weather conditions, study on tourists' consumption preference in industrial heritage resorts is of significance for effectively converting/using industrial heritage resorts, and for compensating the current insufficient research in industrial heritage resorts under extreme weather conditions. This paper, based on a case study on Mentougou's “one-line-four-mines” industrial heritage resort, Beijing city, which had undergone an extreme storm on July 31 ^st , 2023, conducts two questionnaires by means of probability proportional sampling(PPS) and random sampling, recovers 964 valid questionnaires before the storm and 1106 after. All questionnaires, verified through confidence tests, are analyzed via Robust regression, gradual regression and mechanism analysis. Prior to the storm, the tourists understand “one-line-four-mines” more, the charge is more appropriate, the policies are more supportive and the transportation is more convenient, the tourists have a higher touring preference. After the storm, tourists' touring preference aren't largely influenced by their awareness, charge standards, and recognition of touring quality, impaired transportation, but outstandingly positive by their educational degrees. In mechanism analysis, recognition of values and costs plays a key mechanism before storm, and so does recognition of risks after the storm. This paper puts forward suggestions for governments on alerting and emergency response to extreme weather, for industrial heritage resorts on making appropriate charging standards, improving touring facilities and service quality, and supplying customized services for tourist with different educational backgrounds and personalities and increasing tourists' awareness on industrial heritage and eco-environmental protection, aiming at promoting a cointegration between ecological protection and economic development in industrial heritage resorts.

Household as the basic social unit is the major consuming entity. Carbon emission responsibilities established on consumption end are helpful to clarify the stakeholder-based dynamic mechanism for carbon reduction.  The present personal carbon management has a lot of issues, with unclear carbon emission boundary, complex personal carbon trading, personal carbon reduction entangling, and lack of stable management system, which can be resolved if household end as the trading base with urban-rural household carbon account being the core. This paper aims at establishing household carbon account framework on the basis of account range, margin, measurable methods and expandable linkage between urban carbon account and personal carbon sink. This paper summarizes the research situation of personal carbon account and household carbon account, and establishes a urban-rural household carbon account system including three sub-accounts of asset, equity and debits, and determines the measure margin, sampling method and calculation of household carbon account based on China’s featured carbon emission management system. Linkage of urban-rural household carbon account to urban carbon account has been further explained, and its methods have also been designed. Relation between urban-rural household carbon account and  individual carbon inclusion is differentiated. Combination of household carbon account with carbon market, “visible hand” carbon quota market with “invisible hand” carbon reduction equity market provides a new path for household consumption end carbon reduction, which may avoid overlapping responsibilities and easily link to China’s carbon management system. Urban-rural household carbon account can be a vital tool for China’s carbon management and carbon reduction, supporting carbon emission quota allocation, carbon reduction and trading, incentive mechanism design for carbon inclusion and mobilization of multi-level nested carbon reduction systems in cities.

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.

Shale gas was first discovered in southeast Chongqing, where is also the key place for shale gas exploration. Formation of shale gas reservoir is controlled by shale thickness, organic matters concentration, thermal evolution, porosity and preservation. Southeast Chongqing hosts two major shale units of rich organic matters, Niutitang formation of lower Cambrian and Wufeng-Longmaxi formation of upper Ordovician-lower Silurian, both bearing thick sediments, high organic matters concentration, high thermal evolution, especially in Wufeng-Longmaxi formation with favorable geology for potential economic shale gas, also in upper Proterozoic Doushantou formation, Permian Changxing formation, Longtan formatin (Wujiaping formation), and lower Silurian Shiniulan formation (Songkan formation), where shall be a good exploration target of shale gas.  

This paper uses DEA and input/output model to study their overall energy efficiency, variance and causes among 23 resourcesexhausted cities based on their 2010-2014 data, with results showing a general energy efficiency, but variable with areas. Energy efficiency is positively related to economy, high in developed area. In 2014, 50% of the resourcesexhausted cities are at rising their return stage, leaving big room to improve their energy use efficiency. Some cities bear input redundancy, which need to improve their energy efficiency.

Ore resources are a vital base for economic and social development. China’s fast economic growth requires a surging demand of ore resources, leading to a rising disturbance to environment. A balance between ore resources development and environmental protection can not be avoided. This paper, from legislation, execution and justice, analyzes the dilemma in environmental law construction of ore resources exploration, and presents approaches in publicizing laws and regulations, optimizing legislation, enhancing execution and justice, and improving management, which provide a theoretical suggestion for the sustainable development in economy and society, and also provide an index in monitoring and managing ore resources development and a guide in practice.
