本文拓展了Badinger(2005)模型关于同质国家经济一体化影响经济增长的分析方法,比较了不同质国家间经济一体化通过削减关税和改变人力资本在研发部门比重共同影响经济增长的情况。通过对美国和墨西哥1986～2007年间相关时间序列数据的实证检验,发现美墨两国间的经济一体化对两国的经济增长效应具有不同的特点:①虽然经济一体化对美墨两国都具有长、短期的增长正效应,但短期水平效应要比长期增长效应更显著;②经济一体化对美墨两国的增长效应是不对称的,对墨西哥的总效应要比对美国的大;③经济一体化对墨西哥的增长效应是通过技术和投资两条路径传导的,且前者的效应比后者更为显著,而对美国增长效应的传导仅局限于投资这一条路径。
This paper expands on the Badinger (2005) model of economic integration in homogeneous countries that affects economic growth, and compares the effects of economic integration among different countries on economic growth by reducing tariffs and changing the proportion of human capital in the R & D sector. Through the empirical test of relevant time series data between the United States and Mexico from 1986 to 2007, it is found that the economic integration between the United States and Mexico has different characteristics on the economic growth effect of the two countries: (1) Although economic integration has both Long-term and short-term growth positive effects, but the short-term horizontal effect is more significant than the long-term growth effect; (2) the economic integration is asymmetric to the growth effect of the United States and Mexico, and the total effect on Mexico is larger than that on the United States; The effect of economic integration on Mexico’s growth is mediated by both technology and investment. The effect of the former is more significant than that of the latter. However, the transmission of the growth effect of the United States is only limited to the investment path.
