生态工业园区促进城市经济增长了吗?——基于双重差分法的经验证据

Does national eco-industrial park boost urban economic growth?Empirical evidence based on DID

作为绿色发展理念在工业领域内的一种具体实践形式,生态工业园区是解决生态环境恶化和促进区域经济可持续发展的重要途径之一。生态工业园区强调绿色、低碳和循环的发展模式,在兼顾经济发展的基础上,更多强调对生态环境的保护,符合我国建设资源节约型和环境友好型社会的发展目标。利用全国范围内获批的生态工业园区这一准自然实验,运用全国283个城市经济社会统计数据,实证检验了生态工业园区对其所在城市经济增长的影响。实证研究发现:生态工业园区显著促进了所在城市的经济增长,在利用夜间灯光亮度以及改变实证策略等稳健性检验下该结论保持稳健。进一步研究表明,生态工业园区通过促进地区产业结构升级、加剧政府间竞争以及提高地区经济集聚水平等机制影响了城市经济发展。研究结论表明,生态工业园区对城市经济增长有显著的促进作用,绿水青山带来了金山银山。

As a concrete practice form of the green development concept in the industrial field,the national eco-industrial parks are one of the important ways to cure the deterioration of the ecological environment and promote the sustainable development of the regional economy.EIP encourages a green,low-carbon and circular development model.It gives consideration to economic growth;more importantly,it places more emphasis on protecting the ecological environment,which is in line with China’s development goal of building a resource-saving and environment-friendly society.Adopting a quasi-natural experiment of approved national eco-industrial parks across the country,and then using economic and social statistics from 283 cities nationwide,this paper empirically examines the impact of national eco-industrial parks on urban economic growth.The empirical study finds that the national eco-industrial parks significantly play a significant role in urban economic growth.The conclusion remains robust under robustness tests such as using night-time lighting brightness and changing the empirical strategy.Further research shows that the national eco-industrial parks have affected urban economic development by promoting the upgrading of regional industrial structures,increasing inter-governmental competition and raising the level of regional economic agglomeration.The conclusions of this paper indicate that the national eco-industrial parks make a great contribution to urban economic growth,and lucid water and lush mountains indeed bring invaluable assets.
