制造业投入服务化、融资约束与企业污染减排

Manufacturing Input Service,Financing Constraint and Enterprise Pollution Reduction

制造业投入服务化作为企业转型升级的重要途径之一,在给实体部门带来经济绩效的同时,也越来越多地发挥出绿色价值。利用2000—2013年中国工业企业数据库、工业企业绿色发展数据库和世界投入产出表,测度制造业各部门投入服务化水平和工业企业污染排放强度,研究制造业投入服务化与企业污染排放之间的关系及内在作用机制。结果表明:制造业投入服务化可以通过优化企业要素结构、提升企业技术创新水平来降低企业污染排放强度。此外,对制造业投入服务化过程中融资约束的作用进行探讨,发现缓解融资约束有利于减排效应的释放。异质性检验表明,低能耗企业的投入服务化更能发挥出污染减排效应;制造业投入服务化过程中投入国内服务要素更有利于企业实现污染减排,知识密集型服务要素投入带来的减排效应更高。因此,企业应积极将制造业投入服务化理念纳入生产经营活动之中,努力推进制造业绿色转型升级,实现实体经济绿色、高效、可持续发展。

As one of the important ways of enterprise transformation and upgrading,manufacturing input servitization brings economic performance to the real sector,but also plays more and more green value.Using the database of Chinese industrial enterprises,the database of green development of industrial enterprises and the world input-output table from 2000 to 2013,this paper measures input servitization level of various manufacturing sectors and the pollution emission intensity of industrial enterprises,and studies the relationship between input servitization of manufacturing industries and pollution emission of enterprises and its internal mechanism.The results show that the input servitization can reduce the emission intensity of enterprises by optimizing the structure of enterprise factors and improving the level of enterprise technological innovation.In addition,the role of financing constraints is also discussed,and it is found that easing financing constraints is conducive to the release of emission reduction effect.Heterogeneity test shows that the input servitization of low energy consumption enterprises can exert the effect of pollution reduction more effectively.In the process of input servitization,it is more beneficial for enterprises to realize pollution reduction.The input of knowledge-intensive service elements has a higher emission reduction effect.Therefore,enterprises should actively incorporate the concept of manufacturing into their production and operation activities,strive to promote the green transformation and upgrading of the manufacturing industry,and achieve the green,efficient and sustainable development of the real economy.
