基于行业数据的新型工业节能减排效率与技术创新研究

A Research on Industry Energy Saving and Emission Reduction Efficiency and Technology Innovation

本文构建一种基于生产率的新型节能减排指数,测度2007～2013年我国36个工业行业的节能减排效率,并重点分析企业自主创新、国内创新溢出和国外技术引进对工业节能减排效率的影响。研究发现：我国战略性新兴产业、高新技术产业节能减排效率普遍较高,资源、资本、劳动密集型行业节能减排效率普遍较低;企业自主创新对高效率行业作用更明显,国外技术引进对低效率行业影响更突出,国内创新溢出对各行业效率的影响力度基本一致;环境规制、行业企业规模等也是影响节能减排效率的因素之一。

This paper proposes a new ESER index and examines the ESER efficiency of 36 industries of China between 2007 and 2013. Moreover, comprehensive analyses will be focused on the impacts on industrial ESER efficiency brought by enterprise indigenous in- novation, domestic innovation and technology imports. Research shows that strategic emerging industry and hightech industry have higher ESER efficiency, while resource- , capital - and labor - intensive industries display considerably lower efficiency. Although the overall ESER efficiency has been gradually improved, significant polarization could be seen among different industries. Technology innovation plays a positive role in increasing ESER efficiency. The effect of indigenous innovation is more significant in high efficiency industries, while that of technology imports is more noticeable in low efficiency industries. The degree of domestic innovation impacts is similar among different industries. Additionally, environmental regulation and enterprise scale are other important factors in regard to ESER efficiency.
