摘要
长江经济带是我国对外贸易的主要力量,其与中东欧的经贸联系与合作日益密切。为探究中东欧国家绿色发展对长江经济带出口贸易的影响机制及贸易效率,构建随机前沿引力模型,并结合熵权法选择贸易非效率模型中的绿色发展变量,得到变量的作用机制以及双边贸易效率,研究结果表明:中东欧国家绿色发展水平在整体上表现为对长江经济带出口贸易的促进作用,但不同解释变量作用方向不同;长江经济带对中东欧国家的出口贸易效率均值为0.568,国家之间差异明显,多数中东欧国家属于市场扩张型和发展型;波兰、罗马尼亚、捷克的贸易潜力较大,而波黑、摩尔多瓦的贸易潜力值偏小,贸易拓展空间巨大;长江经济带出口贸易效率有明显的空间异质性,上游和下游的出口贸易效率值较高。
The Yangtze River Economic Belt is a major force in China's foreign trade,and its economic and trade ties and cooperation with central and eastern Europe have become increasingly close.In order to explore the influence mechanism and trade efficiency of the green development of Central and Eastern European countries on the export trade of the Yangtze River Economic Belt,a stochastic frontier gravity model was constructed,and green development variables in the trade inefficiency model were selected by combining the entropy weight method to obtain the action mechanism and trade efficiency of the variables.The analysis showed that:On the whole,the green development level of CEE countries can promote the export trade of the Yangtze River Economic Belt,but different explanatory variables have different directions.The average export efficiency of the Yangtze River Economic Belt to CEE countries is 0.568,with significant differences among countries.Most CEE countries belong to the type of market expansion and development.The trade potential of Poland,Romania and the Czech Republic is large,while that of Bosnia and Herzegovina and Moldova is small,with huge space for trade expansion.There is obvious spatial heterogeneity of export trade efficiency in the Yangtze River Economic Belt,with higher export trade efficiency values in the upper and lower reaches.
