摘要
雾霾治理作为污染治理攻坚战的"重中之重",通过加大政府环保支出、提升绿色技术创新有效进行雾霾污染治理,是当前学界关注的重要问题。在对政府环保支出、绿色技术创新和雾霾污染作用机制进行系统梳理,提出相应研究假说的基础上,利用2008—2016年中国216个或104个城市的研究数据,采用面板空间联立方程、动态面板门槛等估计方法,本文较为系统的考察了地方政府环保支出、绿色技术创新对雾霾污染的影响效应。研究发现:本地和邻地政府环保支出均能直接减轻本地雾霾污染,本地政府环保支出还能通过刺激绿色技术创新而间接减轻本地雾霾污染,但邻地政府环保支出的间接治霾效果不显著。此外,政府环保支出对雾霾的治理效果存在门槛效应:当地区绿色技术创新水平较高时,政府环保支出对雾霾污染的抑制作用十分显著;反之则反是。时段比较发现,生态文明建设纳入地方官员政绩考核体系后,政府环保支出的治霾效果显著提升;地区比较发现,除了当地政府环保支出治霾效果面临技术约束外,重点区域政府环保支出对雾霾污染的抑制作用更加明显。
Since the reform and opening up, China′s economy has achieved rapid growth, and the process of urbanization and industrialization has also brought serious ecological and environmental problems. The smog pollution problem represented by PM2.5 is particularly serious, which not only threatens people′s physical and mental health, but also hinders the sustainable development of the economy and society. As regional compound air pollution, smog pollution has the characteristics of spatial agglomeration, especially in key cities with relatively developed economies such as Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta. In order to achieve green development, the government has increased environmental protection spending, but the smog pollution situation has not been effectively curbed. Green technology innovation, as an important means to achieve economic growth and environmental protection, also plays an important role in reducing smog pollution. In addition, government environmental protection expenditures can promote the development of green technology innovation from a regulatory and incentive perspective to improve smog pollution. Therefore, smog control is the top priority of the "tough battle of pollution control". By increasing government environmental protection expenditures and improving green technology innovation, the effective management of smog pollution is an important issue of current academic concern.Based on the data of 216 or 104 cities in China from 2008 to 2016, this paper uses panel space simultaneous equation estimation, dynamic panel threshold methods to systematically investigate the impact of local government environmental protection expenditure and green technology innovation on smog pollution. The main conclusions are as follows:(1) Increased local government environmental protection expenditures in local and neighboring areas can directly reduce local smog pollution;increased local government environmental protection expenditures can also indirectly reduce local smog po
