服务业双向投资开放提高了制造业碳生产率吗?

Does Opening up of FDI and OFDI in Services Improve Carbon Productivity in Manufacturing?

在构建服务业双向投资开放影响制造业碳生产率的理论框架基础上,利用DDF-GLM指数、投入产出方法测算制造业碳生产率以及服务业双向投资开放指数,并使用中国2004—2016年行业层面数据进行实证检验。研究发现:服务业FDI开放会显著提升制造业碳生产率,服务业OFDI开放对制造业碳生产率具有抑制效应;服务业FDI开放更有利于提高低煤炭消耗行业的碳生产率,服务业OFDI开放对低煤炭消耗行业碳生产率的抑制效应更强;与间接使用相比,制造业对服务业FDI的直接使用更有利于提升制造业碳生产率,制造业对服务业OFDI的直接使用对制造业碳生产率的抑制效应更强;服务业FDI开放会通过绿色技术溢出效应、制造业投入服务化效应和成本降低效应显著提升制造业碳生产率;服务业OFDI开放未能通过上述渠道提升制造业碳生产率。

Using DDF-GLM index and the input-output method to measure the manufactories carbon productivity and the services two-way investment opening index, and use China’s industry-level panel data from 2004 to2016 to empirically examine the impact and internal mechanism of services two-way investment opening on services carbon productivity. We have found that: the services FDI opening will significantly increase the services carbon productivity, and the services FDI opening is reflected as the inhibitory effect in the manufactories carbon productivity;the services FDI opening is more conducive to improving the low-coal consumption industries carbon productivity. The low-coal consumption industries have a stronger inhibitory effect. The services FDI will significantly improve the China’s manufactories carbon productivity through green technology overflowing effects, manufactories input servitization, and cost reduction effects;the services OFDI fails to improve the carbon productivity of China’s manufacturing industry through the above channels.
