生產性服務業(yè)投入對中國服務業(yè)全球價值鏈長度的影響

摘要： 隨著中國服務業(yè)參與國際分工程度的深化,生產性服務業(yè)作為主要的中間投入,對于服務業(yè)全球價值鏈長度的影響逐漸加深。本文借助2016年WIOD公布的世界投入產出表,對2000—2014年中國服務業(yè)的全球價值鏈長度和生產性服務業(yè)投入情況進行測算,并構建動態(tài)面板數據,應用系統(tǒng)GMM模型對兩者之間的關系進行實證分析。結果顯示生產性服務業(yè)投入對中國服務業(yè)全球價值鏈長度具有顯著的正向影響。另外,服務業(yè)價值鏈前期狀態(tài)和高技術勞動力均對服務業(yè)全球價值鏈長度的延伸有促進作用,相反,研發(fā)投入的提高則起到了壓縮的效果。
As China's service industry participates in the deepening of international division of labor,the productive service industry as the main intermediate input, the impact on the service industry's global value chain length has gradually deepened. With the World Input-Output Table published by WIOD in 2016,we will measure the global value chain length of China's service industry and the investment in the productive service industry from 2000 to 2014, and construct dynamic panel data,and apply the system GMM model to empirically analyze the relationship between the two. The results show that the investment in productive services has a significant positive impact on the length of the global value chain of China's service industry. In addition,the early stage of the service industry value chain and the high-tech labor force have promoted the extension of the service industry 's global value chain length. On the contrary, the improvement of R&D investment has played a compressive effect.
