GVC嵌入与我国服务业技术进步：机理与实证研究

基于GVC理论和内生增长理论，运用《中国统计年鉴》和UIBE的GVC指标数据库，采用前后向关联测算的GVC长度、参与度与地位指标及数据包络分析对技术进步的测算方法，审视GVC嵌入对服务业技术进步的作用。研究发现：虽然我国服务业及其细分行业呈现一定的规模效应，但技术进步对其发展的促进作用有限，服务业技术进步、技术效率仍需提升；基于前后向关联的GVC长度、参与度及地位与我国服务业技术进步均呈现正U型非线性关系，并位于曲线左侧，即GVC嵌入对我国服务业技术进步有一定的推动作用，正在接近但尚未跨越由抑制作用变为推动作用的底端“拐点”，GVC嵌入对服务业技术进步仍存在较大的上升空间，这也与我国服务业发展还具有较大发展空间的经济现实一致。

Global value chain embeddedness and technical progress in China's service industry: Mechanism and empirical research

Based on the global value chain theory and endogenous growth theory，using the Chinese Statistical Yearbook and the UIBE database issued by the Institute of global value chains of University of International Business and Economics concerning the global value on the forward and backward correlation, we reexamine the mechanism of the effect of Global Value Chain Embeddedness on the technical progress of service industry. The empirical research finds that although China's service industry and its sub-sectors have certain industry-scale effects, technical progress has a limited promotion effect, and technical progress and technical efficiency of service industry still need to be further improved; the length, participation and position indicators of global value chain based on forward and backward linkages have a positive U-shaped nonlinear relationship with China's service industry technical progress, and are located on the left side of the curve now, that is, the global value chain embeddedness has a certain role in promoting the technological progress of China's service industry, it is approaching but has not yet crossed the “inflection point” from inhibition to promotion, and the global value chain embeddedness still has a large room for improvement in the technical progress of the service industry, which is also consistent with the economic reality that the development of China's service industry still has a large development space .
