摘要
ICT产品进口作为企业投入数字化的重要表现形式,可以为企业污染减排提供重要支撑。文章基于2002—2012年中国海关贸易数据库、中国工业企业污染数据库和中国工业企业数据库的合并数据,利用双重差分法识别ICT产品进口对企业污染减排的影响。结果显示,ICT产品进口能够显著降低企业污染物排放强度,且经过一系列稳健性检验后该结论仍然成立。机制检验表明:一方面,ICT产品进口通过提升全要素生产率,促进企业产出规模增长,进而降低企业污染物排放强度;另一方面,ICT产品进口通过优化能源结构、提高能源效率,降低企业污染物排放规模,进而降低企业污染物排放强度。此外,ICT产品进口对大规模企业、技术密集型行业企业和数字经济发展水平较高地区企业的污染减排效应更为明显。基于研究结论,未来可通过鼓励和扩大ICT产品进口、推动ICT产品核心技术研发创新、拓展ICT产品应用场景等途径,实现企业数字化转型与污染减排协同发展。
The import of ICT products,as an important form of enterprise input digitalization,can provide im-portant support for enterprise pollution reduction.Based on the combined data of China Customs Trade Database,China Industrial Enterprise Pollution Database and China Industrial Enterprise Database from 2002 to 2012,this pa-per uses the DID to identify the impact of ICT product import on enterprise pollution reduction.The results show that the import of ICT products can significantly reduce the intensity of pollution emissions of enterprises,and the conclusion is still valid after a series of robustness tests.The mechanism test shows that:On the one hand,the im-port of ICT products can promote the growth of enterprises’output scale and reduce the intensity of enterprises’pollutant emissions by improving total factor productivity;on the other hand,the import of ICT products can reduce the scale of enterprise pollutant emissions by optimizing the energy structure and improving energy efficiency,thus leading to a decline in the intensity of enterprise pollutant emissions.In addition,the import of ICT products has more obvious pollution reduction effect on large-scale enterprises,technology-intensive industry enterprises and en-terprises in regions with higher development level of digital economy.Based on the research conclusion,the collab-orative development of enterprise digital transformation and pollution reduction can be realized by encouraging and expanding the import of ICT products,advancing R&D innovation of core technologies of ICT products,extending application scenarios of ICT products,etc.in the future.
