Research On Pharmaceutical Industry Green Total Factor Productivity In China Under The Background Of Environmental Regulation

After the reform and opening up,China gained the leading position as a world power with the rapid economic growth,while the rapid economic growth was caused by the large consumption of resources and the aggravation of the bad environment.While rapid economic growth is to be celebrated,resource and environmental constraints cannot be ignored.As an important part of the national economy,the pharmaceutical industry is closely related to the lives of the Chinese people.Facing the challenge of balanced development under this situation,we should accelerate the green transformation and upgrading of the industry.The study of green total factor productivity added energy and environmental factors on the basis of the original total factor productivity,which can provide some reference for the scientific evaluation of the quality of economic development,and the related analysis and research of green productivity in the pharmaceutical industry can provide key guidance for the industry to adapt to sustainable development.This paper builds a green production function model based on SBM model and Luenberger productivity index theory,and conducts an empirical analysis on the relevant data of green total factor productivity of pharmaceutical manufacturing industry in 30 provinces and cities in China.The study found that the average annual green total factor productivity of China's pharmaceutical manufacturing industry was about 8.59%,and the overall green production level of China's pharmaceutical manufacturing industry was on the rise.The change of pure technology makes the main contribution to the growth of green total factor productivity,the other two components are not prominent.There is a certain correlation between the level of green production and the level of regional economic development,and the order from high to low is the east,central and west regions.The regional green development is unbalanced,and the eastern region and the central and west regions show an obvious development imbalance.The study points out that the technical level is the leading factor of green production level,and the pharmaceutical manufacturing industry must increase technological innovation and consider the optimal development of industrial aggregation if it wants to enter the greenproduction road quickly.Resource and environment system plays a fundamental role in promoting the growth of green total factor productivity and sustainable economic development.Secondly,the comprehensive environmental regulation intensity index containing three pollutants was constructed,and then the regression test model based on porter hypothesis was established.Finally,the relationship between environmental regulation and green total factor productivity and its decomposition terms in the pharmaceutical industry was analyzed from the perspective of productivity.The regression results show that the intensity of environmental regulation in eastern China presents an "inverted u-shaped" image in the regression analysis of green total factor productivity and components of the pharmaceutical manufacturing industry,which denies the existence of porter hypothesis.In the estimation of green total factor productivity,efficiency and technology,the central and western regions and the whole country are in the left end of a "u-shaped" development state,while in the estimation of scale efficiency,they are in the left end of an "inverted u-shaped" development state.The former supports porter hypothesis,while the latter denies porter hypothesis.In general,the regression test of environmental regulation and green total factor productivity and components of China's pharmaceutical manufacturing industry cannot support the content of porter hypothesis consistently.
