文章以技术扩散的部门差异解释发展中国家工业部门和服务业部门追赶发达国家速度的差异,认为由于贸易开放程度和人力资本积累较低,发展中国家的服务业部门接受技术扩散的程度小于工业部门,因此随着服务业的扩张,发展中国家整体上接受技术扩散的能力也在降低,从而带来其增长的减速。文章以中国1994年到2012年的面板数据,通过双向固定效应模型,得出第三产业占比与国外技术扩散的交互项系数显著为负的结论,从而证明了结构调整对技术扩散影响系数的拉低作用。采用内部工具变量和外部工具进行IV估计,以及采用动态面板模型进行GMM估计,并不改变结论 。
The article explains the differences in the rates of industrial and service sectors in developing countries catching up with developed countries by referring to the sector differences in technology diffusion. It considers that due to the low degree of trade opening-up and the low level of human capital accumulation, the service sector in developing countries is receiving less technical diffusion than the industrial Sectors, developing countries have also been reduced in overall ability to accept technology proliferation as service industries expand, resulting in a slowdown in their growth. Based on the panel data from 1994 to 2012 in China, through two-way fixed effects model, the article draws a conclusion that the coefficient of the interaction between the proportion of the tertiary industry and the diffusion of foreign technology is significantly negative. This shows that the effect of structural adjustment on the coefficient of technological diffusion Low effect. IV estimation using internal and external tools, and GMM estimation using a dynamic panel model do not change the conclusions.
