FDI对中国服务贸易出口结构优化的实证研究

Empirical research on FDI’s optimization of Chinese service trade’s export structure

针对中国服务贸易结构竞争力有待提高的问题,基于FDI的视角,采用ADF检验、协整检验和格兰杰Granger因果检验等实证检验,分析服务业利用外商直接投资(FDI)对服务贸易出口结构竞争力的优化作用,分析表明:长期FDI增加1%,出口结构指数会上升44%;短期服务业的实际利用外商直接投资会偏离其与服务贸易出口结构优化的均衡关系,但是会以较快的速度拉到长期均衡上,其纠正速度系数为-0.944,外商直接投资能够优化中国服务贸易出口结构。

In view of the inadequate structure competitiveness of China’s service trade,an empirical analysis was made of the optimization function of FDI on service trade’s export structure competitiveness based on ADF test,co integration test and Granger causality test from the perspective of FDI.Findings show that the long-term 1% increase in FDI leads to 44% increase in the export structure index;the short-term utilization of FDI in service trade will send the trade diverging from its equilibrium relationship with service trade’s export structure optimization,but this short-term imbalance will return to the long-term balance at a faster speed with its correction rate coefficient at-0.944.Results indicate that an increase in FDI will optimize service trade structure.
