中国产业内贸易水平测度及影响因素研究——基于中国与RCEP部分成员国数据

Research on the Measurement and Influencing Factors of China's Intra Industry Trade Level

基于2010—2019年的面板数据对中国与文莱、柬埔寨、老挝、新加坡、泰国、越南、日本、新西兰和澳大利亚等9个RCEP成员国的产业内贸易水平、变化及其影响因素进行实证分析。结论认为,在样本期内中国与9个RCEP成员国的产业内贸易水平相对较低,平均IIT指数为0.2,充分利用RCEP合作平台,推动中国与其成员国的产业内贸易;从产业内贸易的影响因素看,市场规模差异、人均收入差异对产业内贸易呈负相关关系,贸易平衡程度、贸易开放程度以及外国直接投资则对产业内贸易具有正向影响,其中,两国的市场规模差异与贸易平衡程度是产业内贸易最重要的两个影响因素。

Based on the panel data from 2010 to 2019,this paper conducts an empirical analysis on the level,changes and influencing factors of intra-industry trade between China and 9 RCEP member countries,including Brunei,Cambodia,Laos,Singapore,Thailand,Vietnam,Japan,New Zealand and Australia.The basic conclusions are:During the sample period,the level of intra-industry trade between China and the 9 RCEP member countries was relatively low,with an average IIT index of 0.2,making full use of the RCEP cooperation platform to promote intra-industry trade between China and its member countries;From the perspective of the influencing factors of intra-industry trade,differences in market size and per capita income have a negative correlation with intra-industry trade,while the degree of trade balance,trade openness and foreign direct investment have a positive impact on intra-industry trade.Among them,The difference in market size between the two countries and the degree of trade balance are the two most important influencing factors of intra-industry trade.
