服务业FDI对出口技术复杂度的影响研究——基于OECD国家和中国的经验数据考察

Research on the Effect of Service Foreign Direct Investment on Export Technical Complexity: Based on Empirical Data from OECD Countries and China

本文运用2000-2013年OECD 31个国家和中国的样本数据,检验服务业外商直接投资（FDI）与出口技术复杂度之间的关系。实证结果表明：服务业外商直接投资的增加将会促进出口技术复杂度水平的上升,服务业外商直接投资增加1%,出口技术复杂度将提高0.08%;国内技术进步水平、人力资本、基础设施、金融发展水平、制度质量、产业结构优化、服务业开放度和服务业对外直接投资都是促进出口技术复杂度水平提高的积极因素。本文以各国金融发展水平作为门槛变量构建了门槛回归模型,实证结果显示,服务业外商直接投资与出口技术复杂度之间存在双重金融发展水平门槛值,金融发展水平越高,服务业外商直接投资对出口技术复杂度的积极影响越大。

This paper uses the sample data from 31 OECD countries and China from 2000 to 2013 to test the relationship between service foreign direct investment and export technical complexity. The result shows that increase in service foreign direct investment will increase the level of export technical complexity. If service foreign direct investment increases by 1%, export technical complexity will increase by 0.08%. Meanwhile, domestic technological advancement, human capital, infrastructure, level of financial development, institutional quality, industrial structure optimization, service industry＇ s openness and service industry＇s outward direct investment are also factors that may help to raise the level of export technical complexity. This paper also constructs the threshold regression model which takes the level of financial development as a threshold variable.The empirical result shows that a dual threshold in financial development exists between service foreign direct investment and export technical complexity. With an improvement in the level of financial development, the impact of service foreign direct investment on export technical complexity will be greater.
