Research on the dynamic evolution and convergence of collaborative capacity of pollution control and carbon reduction: from the perspective of whole-process governance.

Under the strategic goals of achieving peak carbon neutrality, deepening the battle against pollution, and building a beautiful China, improving the collaborative capacity of pollution control and carbon reduction is an important means to achieve comprehensive green and low-carbon transformation of the social economy. Starting from the essential requirements of improving the collaborative capacity of pollution control and carbon reduction, based on the whole-process governance perspective of "source-process-end-of-pipe," build an evaluation index system, measure the collaborative capacity, quantify the spatial differences, analyze the evolution characteristics, and explore the improvement path. The study found that China's collaborative capacity of pollution control and carbon reduction is characterized by homogeneous agglomeration and unbalanced regional development.

The impact of digital economy on total factor carbon productivity: the threshold effect of technology accumulation.

This research focuses on the impact of the digital economy on total factor carbon productivity. Based on the panel data of China's provinces from 2009 to 2019, this paper incorporates undesired output, namely carbon emissions, into the evaluation index system, and uses the SBM-ML index to measure regional total factor carbon productivity, and uses the RAGA-PP model to measure the digital economy development index, which includes three dimensions: digital infrastructure, digital industry development, and digital economic environment. Moreover, this paper incorporates the heterogeneous threshold of technological accumulation into the framework of the impact mechanism of total factor carbon productivity and builds a threshold model to examine the impact of the digital economy on total factor carbon productivity under different technological accumulation thresholds.

Research on the impact of energy technology innovation on total factor ecological efficiency.

Promoting sustainable economic development from the perspective of energy technology is crucial, given limited energy resources and severe environmental pollution. Based on the panel data of China's provinces from 2000 to 2017, we empirically explore the complex relation among energy technology innovation, regional economic growth, and total factor ecological efficiency. We innovatively introduce ecological footprint as one of the input indicators of total factor ecological efficiency measured using slack-based measure-data envelopment analysis, thereby comprehensively quantifying sustainable economic development.

Does renewable energy consumption contribute to the development of low-carbon economy? Evidence from China.

Stimulating renewable energy consumption has become a major strategic choice for China to both fulfill the international commitment to reduce carbon emissions and realize the high-quality growth of the domestic economy. On account of the provincial data during the period of 2000 to 2017, we creatively incorporate the ecological footprint into the measurement of low-carbon economy development level through super-efficient SBM model, so as to infer the coordinated development level of 3E system more precisely. Based on the factor substitution effect, energy path dependence effect, and scale effect, the complex nonlinear relationship between the two core research objects is further probed by constructing the threshold regressive model.

Application of Threshold Regression Analysis to Study the Impact of Clean Energy Development on China's Carbon Productivity.

Facing the pressures of international carbon emission reduction, the transformation into a low-carbon economy has become a common issue of all countries. The core of developing a low-carbon economy is to increase carbon productivity, which can be measured as the economic benefits of unit carbon emissions. Therefore, using province-level panel data in China from 2009 to 2017, we analyze the carbon productivity level of each region, and empirically investigate the threshold effect of clean energy development on carbon productivity under different technological innovation levels.
