| Nowadays,under the background of China's economic development entering the new normal,we are not only facing the requirements of a doubling of GDP and per capita income of urban and rural residents by 2020 compared with 2010,achieving the all-round well-off,but also facing severe environmental pollution problems.At the same time,the voice of meeting the people's beautiful ecological environment needs and deepening the relevant mechanisms of green development in the report of the 19th National Congress of the Communist Party of China is still around the ear,so how to balance the relationship between economic development and environmental improvement has become an urgent problem to be solved.The emission trading system is based on the coordinated development of the environment and the economy,therefore,it is necessary to study the relationship between emissions trading and green development based on market-encouraged environmental regulations.This paper first makes a detailed introduction to the emissions trading system and its specific contents,reviews the development course of emissions trading system,and describes its development status from the trading target,distribution and trading situation.Then this paper takes the pilot of the SO2 emission trading system as an example,and visually analyzes the changes in the environmental quality and total industrial output value of the pilot area after the implementation of the SO2 emission trading system from the perspective of"quantity“,and it is found that while the environmental quality has improved,the total industrial output value has continued to grow.Then,this paper takes the panel data of 30 provinces and cities in China from 2002 to 2017 as examples to construct a PSM-DID model.The pilot areas identified in2007 are used as treat groups,and other areas are used as control groups,then the green development effect is divided into economic effect and environmental effect,and the economic effect is measured by the green development score measured by entropy,the environmental effect is measured by the intensity of SO2 emission,and the green development effect of SO2emission trading system is empirically studied.Through empirical research,it is found that the implementation of the SO2 emissions trading system has indeed brought about green development effects,that is,the economic and environmental effects of the pilot area have been improved compared with non-pilot areas,but the effect has decreased with the pilot time is getting longer and longer.The increase in the intensity of R&D investment,marketization index and environmental regulation intensity,and reduction in industrialization can lead to an increase in green development scores and a reduction in the intensity of industrial sulfur dioxide emissions,bringing the significant economic and environmental effects.In the end,this article gives the relevant policy suggestions to improve the green development effect of the emissions trading system,including continuing to optimize the trading mechanism of emissions trading,increasing investment in research and development,giving more autonomy to the market,and establishing an environmentally-oriented government to help green development. |
