摘要
文章采用2003—2011年中国31省市面板数据分析了贸易开放条件下产业集聚对能源效率的影响,并运用门槛面板模型和线性模型对两者之间的关系进行了实证检验。研究结果表明,我国产业集聚对能源效率的影响存在贸易开放三门槛效应,当贸易开放水平处于较低水平时其影响不显著,只有在贸易水平超过一定门槛值后该影响效果才会显著,并且随着贸易水平的不断提高而增大。同时,本文的政策建议侧重于两个方面:一是提高对外开放水平,二是提高产业集聚水平。
Based on the panel data of China' s 31 provinces and cities from 2003 to 2011, the paper analyzes the impact of industrial agglomeration on energy efficiency under the conditions of trade openness and makes an empirical study of the relationship between industrial agglomeration and energy efficiency with the threshold panel model and linear model. The results show that as far as the impact of industrial agglomeration on energy efficiency is concerned in China, there exist three threshold effects in trade openness. When trade openness is at a low level, the impact is not remarkable. Only when trade openness is above a certain threshold level, will the impact become remarkable. Furthermore, the impact will increase constantly with the improvement of trade openness. Meanwhile, the paper puts forward the suggestions of improving the level of both trade openness and industrial agglomeration in two aspects.
