The Impact of Environmental Regulation on Urban Green Efficiency—Evidence from Carbon Pilot

This article measures the green total factor productivity of 30 provinces (cities) in China from 2008 to 2018 based on the DEA superefficient nonexpected output model, utilizes the carbon emissions trading pilot policy as a quasi-natural experiment, and uses the multiperiod double-difference model and spatial econometric approach to test the effectiveness of carbon emissions trading policy. The results found that carbon emissions trading policies can significantly improve the GTFP of the pilot regions through three main approaches: adjusting the energy mix, improving resource misallocation, and promoting green technological innovation. The market mechanism measured by carbon price and the government administrative intervention measured by fiscal dependence will increase regional GTFP. The spatial and temporal evolution pattern analysis and DSDM show a “pollution refuge” effect in the initial stage of carbon emissions trading; however, the carbon trading pilot can form a demonstration effect in neighbouring areas and promote the improvement of GTFP in neighbouring areas afterwards. The study will help enrich the performance evaluation framework of carbon emission trading policies and further improve the institutional construction of the national carbon market

A comparative analysis on the factors promoting China's economic growth based on demand

AbstractBy applying co-integration test and variance decomposition to the quarterly data from Q1 2000 to Q3 2010, this paper conducts an empirical study on the demand factors that promote the economic growth of China. The conclusions are as follows: consumption, investment and net exports all have influence on China's actual output, among which, consumption makes a greater contribution to the economic growth than investment and net exports. In addition, by studying the time-varying effectiveness, we also notice that consumption has the most effectiveness on stimulating economic growth, while investment is the less and net exports is the least. Based on the above two theories, we put forward some suggestions how to promote China's economic growth continually
