在平衡中推动绿色发展:偏向西部的区域协调发展是否促进污染物减排?

Promoting Green Development in Balanced Development:Does the Regional Coordinated Development of the Western Region Lead to Pollutant Emission Reduction?

本文以西部大开发为例,研究发现,为实现区域协调发展的政策存在显著的绿色发展效应,经过一系列稳健性检验后结果依旧成立。机制分析表明,区域协调发展政策主要通过技术溢出的方式促使企业提升自身技术效率而降低污染排放,同时还发现清洁产业结构调整以及资源再配置也是推动绿色发展的重要途径。进一步研究发现,高产出水平的企业选择通过提升技术效率的方式进行污染减排,而低产出水平的企业则可能更注重增加污染治理投资。

Taking the"Great Western Development"as an example,it is found that there is a significant green development effect of the policy of achieving coordinated regional development,and the results are still valid after robustness tests.Mechanism analysis shows that technology spillover effect promotes enterprises to improve their own technical efficiency,resulting in pollution emission reduced.Meanwhile,industry restructuring and resources reallocation are also important paths to promote green development.Further research reveals that companies with high output levels choose to reduce pollution by improving technical efficiency,while companies with low output levels may prefer to increase pollution abatement investment,
