摘要
运用基于跨期生产前沿的方向性距离函数(IFDDF)测度了2001-2014年中国各省份的绿色发展效率,并利用Tobit和2SLS法实证检验了进出口贸易对中国绿色发展效率影响的区域差异。整体而言,进口贸易显著提高了中国的绿色发展效率,但出口贸易对绿色发展效率改善存在阻碍作用;分地区看,东部和西部的进口贸易对绿色发展效率有显著正影响,中部的进口贸易对绿色发展效率有显著负影响,东部和中部的出口贸易对绿色发展效率是显著促进作用,而西部的出口贸易则抑制了绿色发展效率的提高。
The paper measured the green development efficiency of China's provinces in 2001-2014 based on the function Inter-temporal Frontier DDF,and empirically tested the effect of import trade and export trade on China's regional green development efficiency by estimation methods of Tobit and 2SLS.It found that the import trade can significantly promote the national green development efficiency,while the export trade is harmful to the improvement of the national green development efficiency.From the regional perspective,the import trade has a significant positive impact on the green development efficiency of the eastern and western of China,but has a significant negative impact on the central of China,while the export trade has a significant positive impact on the green development efficiency of the eastern and central of China,but has a significant negative impact on the western of China.
