It is of theoretical and practical significance to study the impact of mixed-ownership reform, the core measure of stateowned enterprise (SOE) reform, on the green innovation of SOEs. Using the data of SOEs listed in the China A-share stock market from 2010 to 2019, this study empirically tested the impact, mechanisms, and heterogeneous impact of mixed-ownership reform on the green innovation of SOEs through a Propensity Score Matching+Difference-in-Differences (PSM-DID) model based on the shareholding ratio of non-state-owned shareholders among the top ten shareholders of state-owned enterprises. On this basis, this paper further explored the spillover effect of mixed-ownership reform on the green innovation of SOEs. The results showed that: ① Mixed-ownership reform could effectively promote the green innovation of SOEs. After using the placebo test and instrumental variable method to alleviate the endogenous problem and replacing the matching basis for the robustness test, the conclusion was still valid. ② The mechanism test showed that the improvement of corporate governance level and the knowledge spillover effect were important channels for mixed ownership reform to promote the green innovation of SOEs. The profit-seeking nature of non-state-owned shareholders might have a dampening effect on the green innovation of SOEs in mixed-ownership reform. ③ The heterogeneity analysis of industry characteristics showed that in competitive industries and environmental protection industries, mixed-ownership reform had a more obvious impact on promoting the green innovation of SOEs. ④ Although the mixed-ownership reform promoted the green innovation of SOEs, it was not the higher the better in terms of the proportion of non-state-owned shareholders. When non-state-owned shareholders accounted for 15% to 30%, the promotion effect on the green innovation of SOEs was most obvious. ⑤ The mixed-ownership reform had a spillover effect on the green innovation of unreformed SOEs, effectively promoting the substantive green innovation of these SOEs in the same industry. Therefore, the study proposes that the important role of mixed-ownership reform in green development should be fully recognized and the mixed-ownership reform of SOEs should be further promoted. We should promote the formation of a mutually balanced equity structure and rationally allocate the proportion of non-state-owned capital. At the same time, we should avoid the ‘one-size-fits-all’ mixed-ownership reform and adhere to the classification and stratification of orderly progress. [ABSTRACT FROM AUTHOR]

The system as a whole is composed of various interrelated sub-systems. The effect of a system will be affected by the coordination of other systems associated with it. Only when the complementarity and coordination between systems increase can the implementation effect of the system be fully brought into play. As an informal system, social trust can affect the implementation effect of formal environmental regulations, but there are few studies on the moderating effect of social trust on the impact of environmental regulations on carbon emissions. Based on this, the panel data of 281 prefecture-level cities in China from 2010 to 2019 were selected as research samples. The moderating effect model and mediated moderating effect model were used to study the moderating effect and mechanism of social trust on the impact of environmental regulations on carbon emissions. In addition, the heterogeneity of this moderating effect was tested by region. The results showed that: ① The impact of environmental regulations on carbon emissions showed an inverted Ushaped nonlinear relationship, and the promotion effect of environmental regulations on carbon emissions was dominant in the present stage. FDI, the upgrading of industrial structures, and R&D innovation were important mediating channels for environmental regulations to affect carbon emissions. ② As a moderating variable, social trust positively moderated the impact of environmental regulations on carbon emissions and accelerated the arrival of the inflection point of the inverted U-shaped curve. ③ In terms of the mediating effect, the moderating effect of social trust on the impact of environmental regulations on carbon emissions was realized through the mediating effect of FDI, the upgrading of industrial structures, and R&D innovation, and the impact of social trust on the inflection points of the three intermediary channels was heterogeneous. ④ The moderating effect of social trust had regional heterogeneity. In small cities, the impact of social trust on environmental regulations on carbon emissions was greater than that in large and medium-sized cities. The moderating effect of social trust was greater in the cities without environmental protection than in the cities with environmental protection. The above conclusions were still valid after a series of robustness tests. It is hoped that this paper can enrich the relevant research on environmental regulations and social trust and be helpful for local governments to formulate relevant policies according to local conditions, improve the carbon emission reduction effect of environmental regulation, and accelerate the green development and transformation of Chinese cities.

The energy endowment characteristics of "relatively rich in coal, poor in oil, less natural gas, and uranium deficiency"in China result in that the coal resources as the China’s main energy will not change in the short term.Meanwhile, the relatively abundant coal resources are still the most stable and cost-effective competitive minerals in China.There should be a clear understanding that it is unrealistic, unwise and unscientific to abandon the actual energy choices based on coal to solve China’s energy problems. However, it should be noted that the coal resources have brought about environmental pollution, ecological damage, waste of resources, and high emissions in the whole process from geological exploration to development and utilization.Therefore, the development of the coal industry in China will certainly undergo some significant changes in the new era.Implementing scientific exploration and development, clean utilization, and low-carbon consumption, characterized by science, safety, ecology, high efficiency, standardization, digitization, and intelligence, is the only way to realize the sustainable development of China’s coal industry.Aimed at the challenges and opportunities for the coal industry in China, the present situation and existing problems of coal resources in the whole process from geological exploration to development and utilization is analyzed, and the strategic thinking of building an upgrade version of main energy( coal) industry in China is proposed.In this paper, the authors focus on 11 key scientific and technological problems faced in the process of realizing the upgrade version of China’s main energy( coal) industry, namely the problems of comprehensive coordination, green exploration, deep exploration, and intelligent exploration for coal resources in the process of geological exploration; the problems of green, safety, recovery rate, occupational health, and high benefit in the coal development process; the clean and low-carbon problems in the process of consumption and utilization.Meanwhile, the corresponding exploratory solutions are put forward.It is of great theoretical significance and practical value to promote the transformation and upgrading for China from a large coal producing country to a powerful coal industrial country, and also to address the sharp contradiction between China’s current economic and social development and the protection of ecological environment.
