摘　　要：本文利用2000—2012年中国工业企业污染数据,从微观企业层面系统考察进口技术复杂度对企业能源效率的影响及其作用机制。研究结果显示,进口技术复杂度显著促进了企业能源效率的提升;在考虑样本选择性偏误、变量的内生性及使用不同的衡量指标后,核心结论仍然成立;进一步的异质性检验发现,进口技术复杂度对企业能源效率的促进作用在出口企业、外资企业、加工贸易企业及东部地区企业中更为显著。此外,机制检验表明进口技术复杂度通过技术外溢效应和竞争效应提高企业能源效率。Based on the pollution data of Chinese industrial enterprises from 2000 to 2012,this paper systematically examines the impacts of import sophistication on enterprises energy efficiency from the micro-enterprise level.The research results show that import sophistication significantly improves the energy efficiency of enterprises.The core conclusions of this article are still valid after sample selection bias and the endogenous nature of variables are taken into consideration and different measurement indicators are used.In addition,an intermediary effect model is constructed to examine how import sophistication affects the energy efficiency of enterprises.It is found that the“technology spillover effect”and the“competition effect”brought about by import sophistication are two channels to promote the improvement of enterprises energy efficiency.Import sophistication has a stronger role in promoting the energy efficiency of exporting companies than that of non-exporting companies.The possible explanation is that compared with the non-exporting enterprises,when exporting enterprises learn from foreign advanced technology and management experience to improve their energy efficiency,their higher productivity and familiar technical improvement methods are more adept at absorbing the advanced energy-saving technology.Therefore,import sophistication has greater impacts on improving the energy efficiency of exporting companies.Besides,import sophistication plays a greater role in promoting the energy efficiency of foreign-funded enterprises than that of domestic enterprises.The possible reason is that there is a generation gap between the foreign technology and the domestic technology grasped by domestic companies,thus it s hard for domestic companies to fully absorb the foreign advanced energy-saving technologies;whereas foreign-funded enterprises,inherently“foreign”without any technological gaps,can seamlessly connect with foreign advanced energy-saving technologies,so foreign-funded enterprises are better at
