集聚外部性、环境技术效率与节能减排

Agglomeration Externality,Environmental Technology Efficiency and ESER

利用2001～2008年中国制造业面板数据,实证分析了由专业化集聚带来的马歇尔外部性和由多样化集聚带来的雅各布斯外部性对环境及工业协调性的影响,试图寻求新的节能减排的政策着力点。研究发现:马歇尔外部性和雅各布斯外部性都与代表环境及工业协调性的环境技术效率呈"倒U型"曲线关系;马歇尔外部性和雅各布斯外部性会对环境及工业协调性共同起作用。建议政府积极利用这两种外部性正效应实现节能减排。

Using the penal data of Chinese manufacturing industries from 2001 to 2008, this paper analyzes the influ- ences, posed by the Marshallian externalities brought by specialized agglomeration and Jacob＇ s externalities brought by diversified agglomeration, on the environmental and industrial coordination. It tries to find out the new policy-making support for ESER. The conclusion shows： both Marshallian externalities and Jacob＇ s externalities show an reversed U curve with environmental technology efficiency; Marshallian externalities and Jacob＇ s externalities both work on the envi- ronment and industrial coordination. Policy-makers should make use of the beneficial factors of two different externalities to realize ESER.
