通过利用面板协整方法研究贸易开放、收入不平等和经济增长之间的关系,研究发现当收入不平等程度较低时,贸易开放有利于经济增长;而当收入不平等程度较高时,贸易开放则会不利于经济增长。由于我国当前收入不平等程度较大,贸易开放将阻碍经济增长。一方面我国各地区政府应慎行贸易开放政策,另一方面缩小收入差距已成为当务之急。 By using the panel cointegration method to study the relationship between trade openness, income inequality and economic growth, we find that when the income inequality is low, trade liberalization is good for economic growth. When the income inequality is high, trade Opening up will be detrimental to economic growth. Due to the current level of income inequality in our country, the opening up of trade will hinder economic growth. On the one hand, the government of all regions in China should make its trade liberalization cautious. On the other hand, narrowing the income gap has become a top priority.
