笔者尝试性地将对外开放的含义分为两个层面:规模层面(扩大对外贸易额、利用外资额的规模)、制度技术层面(引进吸收外来的先进技术、管理经验、先进制度)。选用1980~2013年时间序列数据,重新构建了对外开放度指标和市场化进程指标,利用Eviews7.2软件对两个变量进行了协整分析,在建立VAR模型基础上进行了Granger因果检验分析、脉冲效应分析、方差分解分析。实证结果揭示:市场化改革会促进对外贸易额和利用外资额规模的扩大,但对外贸易额和利用外资额规模的扩大,对市场化改革进程的促进作用微乎其微。 The author tentatively divides the meaning of opening to the outside world into two aspects: the scale (expanding the volume of foreign trade and the amount of foreign capital utilized) and the institutional technology (introducing advanced foreign technologies, management experience and advanced systems). Using the time series data from 1980 to 2013, we reconstructed the index of openness and the index of marketization process. Cointegration analysis was performed on the two variables using Eviews7.2 software. Based on the VAR model, Granger causality test was carried out. Impulsive effect analysis, variance decomposition analysis. The empirical results reveal that the marketization reform will promote the expansion of the volume of foreign trade and the amount of foreign capital used. However, the expansion of the volume of foreign trade and the amount of utilized foreign investment will have little effect on the marketization reform.
