| Since the forty years of reform and opening up,China’s economy has made rapid development,with a total GDP of 900390 trillion yuan in 2018 and aper capita annual income of 9732 US dollars,which is higher than the average level of middle-income countries.But high-speed economic growth is achieved through high-input,high-energy consumption,high-pollution,low-efficiency modes of production formed by excessive dependence on energy and resource consumption.In 2017,only 99 of the 388 cities at the prefectural level and above reached the standard.The average annual concentrations of PM2.5 and PM10 in domestic cities μg/m3 44 and 80,respectively far exceeds the safety standards published by the World Health Organization.Environmental problems not only become an important factor restricting the sustainable development of our economy,but also become an important killer of citizens’ health.Total factor productivity,as an important index to measure the level of economic develop ment,is an important basis for judging the transformation of economic develop ment mode,improving economic quality and promoting green and sustainable economic development.Therefore,it is indispensable to adopt environmentalreg ulation policy to deal with the severe ecological environment problems brought by China’s rapid industrialization.At the same time,if environmental regulation policies can force enterprises to change the mode of production and improve their total factor productivity,then ring Environment regulation can also be an institutional arrangement to achieve high-quality development.However,most of the previous studies on the impact of environmental regulation on production efficiency are based on the overall macroeconomic data,or industrial level data,and lack of micro-base,and the results of empirical analysis are difficult to be used as the basis for scientific decision-making.Two aspects of this paper are improved: first,using the micro data of China Industrial Enterprise Database to estimate the total factor productivity of enterprises;second,using a variety of methods to estimate the micro total factor productivity of enterprises.As one of the important industrial manufacturing sectors,cement industry plays an important role in infrastructure construction,and is also the main industrial sector of the source of environmental pollution.In this paper,using the micro data of 55 cement industry enterprises in China Industrial Enterprise Dat abase from 1998 to 2008,the comprehensive index is constructed first,and the environmental regulation intensity of cement industry is quantitatively evaluated by using the rate of wastewater reaching the standard,the removal rate of sulfur dioxide and the utilization rate of solid waste.The second is to use ordinary least square method,OP method,LP method and ACF method to calculate the total factor productivity of micro enterprises in cement industry.Final Based on the strength of environmental regulation in cement industry and total factor productivity of enterprises,a econometric analysis model is constructed to evaluate the impact of environmental regulation on total factor productivity of enterprises.The results show that: first,the intensity of environmental regulati on in China’s cement industry shows a "W" trend;second,the total factor productivity of enterprises in China’s cement industry shows a fluctuating upward trend;third,there is a " U" relationship between the intensity of environmental regulation and the total factor productivity of enterprises;fourth,the R & D in vestment,profit margin and labor ratio of enterprises have a positive impact on the total factor productivity of enterprises;fifth,the impact of environmental regulation intensity on the productivity of enterprises showing significant regional differences.Based on the above empirical results,this paper puts forward the following policy suggestions: first,improve the environmental regulation policy of cement industry,and ensure the cement industry to achieve industrial structure optimization and upgrading.Second,speed up the establishment of nationwide cem ent industry environmental regulation joint defense joint control mechanism.Third,give full play to the role of the government to make use of the "double dividend" of environmental regulation policy to improve the support for the trans formation of production mode in cement industry.Fourth,the cement industry itself should improve its own R & D investment,improve its own production efficiency. |
