对外直接投资、结构转型与绿色全要素生产率

Outward Foreign Direct Investment (OFDI), Structure Transformationand Green Total-Factor Productivity

在理论分析基础上,基于2003—2017年中国省际面板数据,利用Global Malmquist-Luenberger(GML)生产率指数测算了各省份的绿色全要素生产率,并通过构建动态面板模型和面板门槛模型深入探讨对外直接投资(OFDI)、结构转型与绿色全要素生产率之间的关系。研究结果表明,OFDI对绿色全要素生产率的逆向技术溢出效应尚未显现;结构转型促进了绿色全要素生产率的提高;OFDI与结构转型对绿色全要素生产率存在协同提升效应。OFDI、结构转型对绿色全要素生产率的影响存在时空差异。进一步研究发现,当OFDI为门槛变量时,结构转型对绿色全要素生产率的影响起到先抑制后促进的作用。基于以上结论,中国应当深化对外开放,进一步实施"走出去"战略,优化产业结构,从而助推中国经济实现绿色转型。

On the basis of theoretical analysis,with China s inter-provincial panel data from 2003 to 2017,the Global Malmquist-Luenberger(GML)productivity index is used to measure the green total-factor productivity of each province,and a dynamic panel model and a panel threshold model are built to explore deeply the relationship between OFDI,structure transformation and green total-factor productivity.The research results show that:(1)The reverse technology spillover effect of OFDI on green total-factor productivity has not yet appeared,structure transformation has promoted green total-factor productivity,and OFDI and structure transformation have a synergistic effect on green total-factor productivity.(2)There are temporal and spatial differences in the impact of OFDI and structure transformation on green total-factor productivity.(3)Further research has found that when OFDI is set as the threshold variable,the impact of structure transformation on green total-factor productivity shows the feature of“first restrained and then promoted”.Based on the above conclusions,China should deepen its opening to the outside world,further release its“Going Out”strategy,and optimize its industrial structure,so as to promote the green transformation of economy in China.
