工业是中国最大的能源消费部门和环境污染的主要来源。提高产业生态效率对中国实现高质量发展具有重要意义。基于2006 - 2015年中国30个省份工业部门的面板数据，采用动态网络数据拟合分析方法评价工业部门生态效率，并运用面板Tobit回归模型考察产业政策对工业部门生态效率的影响。结果表明：（1）2006-2015年中国省级工业部门的总体生态效率为0.7581，工业生产过程的平均效率高于废物处理过程的平均效率。(2)各地区工业部门生态效率差异较大，东部地区最高，西部和中部次之，东北地区最低。(3)产业集聚阻碍了产业生态效率的提高，而产业结构合理化可以促进产业生态效率的提高。(4)产业集聚和产业结构合理化对工业废物处理过程效率的影响大于对工业生产过程效率的影响。本文的研究结果揭示了提高工业子过程效率的重要性，也为其他工业化国家提高工业生态效率提供了借鉴。
The industrial sector is the largest energy consumption sector and major source of environmental pollution in China. Improving the industrial eco-efficiency is significant for China to realize high-quality development. Based on the panel data of industrial sector in China's 30 provinces from 2006 to 2015, this paper first adopts a dynamic network data envelopment analysis to evaluate the eco-efficiency of industrial sector, and then uses panel Tobit regression model to investigate the impacts of industrial policies on the eco-efficiency of industrial sector. The results reveal that, (1) the overall eco-efficiency of China's provincial industrial sector is 0.7581 during 2006-2015, and the average efficiency of the industrial production process is higher than that of the waste treatment process. (2) The eco-efficiency of the industrial sector differs greatly by region, the eastern region is the highest, followed by the western and central regions, and the northeast is the lowest. (3) Industrial agglomeration impedes the improvement of industrial eco-efficiency, while industrial structure rationalization can promote industrial eco-efficiency. (4) The influence of industrial agglomeration and industrial structure rationalization on the efficiency of industrial waste treatment process is larger than that of the industrial production process. The findings of this paper reveal the importance of improving the efficiency of industrial subprocesses, and can also offer lessons for other industrialized nations to improve the industrial eco-efficiency.
