基于Johnson的理论模型,本文分解了我国出口贸易的二元边际,实证发现企业资金依赖度严重制约着企业外延边际的扩张,对内延边际则相对作用较小;抵押品对内延边际有更加良好的促进作用。研究表明当前世界经济正处于“缓增长,慢萧条”态势,政策上我国需要重视内需并鼓励金融改革,鼓励企业选择多元化地理市场,促进外延边际发展。
Based on Johnson’s theoretical model, this paper decomposes the dual marginal of China’s export trade. It is found that the dependence of enterprise’s funds severely restricts the expansion of the enterprise’s extension of the external margin, while the relative contribution to the internal extension of the margin is relatively small. A good role in promoting. The research shows that the current world economy is in a situation of “slow growth and sluggish growth.” In terms of policies, China needs to pay attention to domestic demand and encourage financial reform. Enterprises should be encouraged to choose a diversified geographic market and promote the development of the expansion of the externalities.
