生产性服务业FDI对我国制造业效率的影响——基于交通基础设施水平的门槛效应

The Impact of Productive Service Industry FDI on China's Manufacturing Efficiency——Threshold Effect Based on Traffic Infrastructure Level

生产性服务业FDI对制造业效率具有一定的促进作用,但二者的关系受到一系列东道国区域发展因素的影响。从区域交通发展水平对二者关系的影响视角出发,利用2006～2015年中国21个省级单位的面板数据对交通基础设施水平的门槛效应进行实证检验,结果表明:生产性服务业FDI对制造业效率的影响作用因区域交通基础设施水平的不同而呈现出差异的区间效应,表现为交通基础设施水平较低时,生产性服务业FDI对制造业效率的促进作用相对较弱;当交通基础设施水平突破门槛值后,生产性服务业FDI对制造业效率的促进作用显著变强。此外,考虑到区域差异性后发现,各地区交通基础设施水平对二者关系的影响强度具有明显差异,西部地区通过改善交通基础设施水平从而提升二者正向关系的幅度最大,中部地区最小,东部地区居中。

Productive service industry FDI can improve manufacturing efficiency to some extent,but the relationship between them is influenced by a series of regional development factors of the host country. From the perspective of the impact of regional transportation development level on the relationship between productive service industry FDI and manufacturing efficiency,an empirical study is conducted in this paper to test the threshold effect of the transportation infrastructure level based on the panel data of 21 provincial-level units in China from2006 to 2015. The result indicates that the impact of FDI on the efficiency of manufacturing services varies due to the different levels of regional transportation infrastructure,and the internal effect arises. The productive service industry FDI has a relatively weak effect on manufacturing efficiency when the level of transportation infrastructure is low. When the level of transportation infrastructure exceeds the threshold,the productive service industry FDI has a more significant effect on manufacturing efficiency. In addition,when the regional difference is taken into consideration,it is found that the impact of the level of transportation infrastructure in each region on the relationship between them has significant differences. In the western region,the positive relationship is promoted to the maximum by improving the level of transportation infrastructure. The positive relationship is to the minimum in the central region. The positive relationship in the eastern region is at an intermediate level.
