服务业FDI、技术溢出与地区吸收能力——基于非线性面板平滑转换模型

FDI in Service,Technology Spillover and Regional Absorptive Capacity——Based on the Panel Smooth Transition Regression Model

利用2004—2014年我国服务业省际面板数据,以经济发展水平、对外开放程度、研发投入强度和法律保护作为地区吸收能力的衡量指标,采用面板平滑转换(PSTR)模型,研究中国服务业FDI技术溢出的非线性效应。结果表明,以上4个指标衡量的吸收能力对服务业FDI技术溢出皆存在门槛效应。当转换变量所代表的吸收能力跨过门槛值之后,服务业FDI具有较为显著的技术溢出效应,不同地区的服务业FDI技术溢出存在明显的非均衡性。

This paper selects China＇s provincial panel data of service industry from the years 2004 to 2014, takes level of economic de- velopment, level of opening, R＆D intensity and legal protection as measuring index of regional absorptive capacity, and adopts panel smooth transition regression （PSTR） model to study the nonlinear effect of FDI technology spillover in China＇s service industry. The research results show that there exists threshold effects among the four above indexes of absorptive capacity to the FDI technology spillover in service industry. When the absorptive capacity represented by the transition variable is beyond the threshold value, the FDI in service industry has a significant technology spillover effect; and the FDI technology spillovers in service industry in different regions are obviously unbalanced.
