Analysis On The Efficiency Of Air Pollution Prevention And Control From The Perspective Of Meta-Governance

The Yangtze River Delta region,as one of the key areas for joint prevention and control of air pollution in China,has attracted more and more attention from scholars in recent years.First of all,this research distinguishes four main stages of air pollution prevention and control in my country,namely,the administrative control period,the initial rule of law,the comprehensive prevention period,and the multi-subject participation in governance.It has a preliminary understanding of the background of the changes in air pollution prevention and control policies.Based on the guidance of meta-governance theory,the framework of the governance model for the prevention and control of air pollution in China has been constructed.Then,the texts of air pollution prevention and control policies in three provinces and one city in the Yangtze River Delta are analyzed in two dimensions:quantity and content.The results of the analysis are:2010 is the first year of air pollution control in the Yangtze River Delta,and the characteristics of the control modes of three provinces and one city are summarized separately.Shanghai adopts a comprehensive governance model based on bureaucratic governance,supplemented by market and network governance;Jiangsu Province adopts a comprehensive governance model featuring the balanced development of bureaucracy,market and network;Zhejiang province adopts a bureaucratic governance model,market comprehensive governance model used in conjunction with the network;while the comprehensive governance model adopted by Anhui Province is based on the combination of bureaucracy and the market,and network governance as a supplement.Taking 2010 as the demarcation point,two super-efficiency DEA models were established to evaluate the efficiency of air pollution prevention and control in the Yangtze River Delta.Model I measures the efficiency of air pollution prevention and control in the Yangtze River Delta from 2001 to 2010 from the perspective of manpower,material resources and capital investment.The results show that the air pollution prevention and control efficiency varies greatly among provinces and cities.Among them,Shanghai and Anhui provinces have higher air pollution prevention and control efficiency,while Jiangsu and Zhejiang provinces have lower efficiencies.There is redundancy in equipment and capital investment in the prevention and control of air pollution in Zhejiang Province,and there is also a problem of redundancy in personnel investment in Jiangsu Province.ModelⅡ selects representative variables to represent the input of the three governance models of bureaucracy,market,and network in air pollution prevention and control,in order to evaluate the value of air pollution prevention and control efficiency in the Yangtze River Delta from 2011 to 2017.The results show that the efficiency values vary greatly among provinces and cities.Anhui Province and Shanghai are still more efficient,while Zhejiang Province and Jiangsu Province have low efficiency values.Both non-DEA provinces have multiple governance model investment redundancy.Based on the above analysis,suggestions for improvement of air pollution prevention and control in the Yangtze River Delta include:First,improve the efficiency of project investment funds,streamline institutions and personnel,and upgrade equipment in a timely manner;Second,coordinate bureaucracy,market,and network,to improve the efficiency of meta-governance.
