摘　　要：为研究消化吸收调节下中国对外直接投资(outward foreign direct investment,OFDI)对母国绿色全要素生产率(green total factor productivity,GTFP)的影响,使用非径向、非角度的基于松弛的方向距离函数,结合曼奎斯特-卢恩伯格(Malmquist-Luenberger,ML)指数测算中国地区GTFP水平,并利用2003—2019年中国省级面板数据和面板门槛模型,实证分析中国OFDI对母国GTFP影响的门槛效应。结果表明:1)中国OFDI对母国GTFP存在显著的正向影响,并且该影响受到母国消化吸收能力的正向调节,即人力资本越丰裕,研发投入越密集,中国OFDI对母国GTFP提升的作用越明显。2)门槛回归结果显示,消化吸收在中国OFDI对母国GTFP提升的作用中存在非线性门槛效应,人力资本和研发投入均表现出正向且边际效率递增的非线性门槛规律。可见,OFDI正向驱动GTFP增长。本研究结果对中国改善经济环境,实现绿色经济转型具有借鉴意义。In order to study the effect of China’s outward foreign direct investment(OFDI) on home country’s green total factor productivity(GTFP) under the moderation of digestion and absorption,China’s regional GTFP level was guessed and estimated by applying the non-radial,non-angle,relaxation-based direction distance functions,combined with the Malmquist-Luenberger(ML) index,and then an empirical analysis was made into the threshold effect of China’s OFDI on home country’s GTFP by using China’s inter-provincial panel data from 2003 to 2019 and the panel threshold model.The results show that:1) China’s OFDI has a significantly positive impact on home country’s GTFP,and this effect is positively regulated by home country’s digestion and absorption capacity,that is,the more abundant the human capital and R&D investment is,the more obvious the promoting effect of China’s OFDI on home country’s GTFP is.2) Threshold regression results show that there is a nonlinear threshold effect of digestion and absorption on the effect of China’s OFDI on home country’s GTFP.Human capital and R&D investment both show a positive and increasing marginal efficiency of the non-linear threshold law.Thus,it is concluded that OFDI is the positive driver of GTFP.The results of this study can provide reference for China to improve the economic environment and to transform the green economy.
