近年来,非正式部门对国际贸易的影响是国际经济研究的新话题。现有研究认为非正式部门的存在阻碍了中国与发达国家整体对外贸易的发展。当前,中非经贸关系迅猛发展,在非洲经济活动中占重要地位的非正式部门又会对中非贸易产生怎样的影响呢?文章使用中国对非洲45个国家2003~2012年的贸易相关数据建立引力模型,检验非正式部门对中非贸易的影响。研究结果表明,非正式部门的存在短期内阻碍了中非贸易的发展,而长期影响并不显著。
In recent years, the impact of the informal sector on international trade has been a new topic in international economic research. Existing research suggests that the existence of the informal sector hinders the overall development of foreign trade between China and the developed countries. At present, the rapid development of China-Africa economic and trade relations and the informal sector that plays an important role in African economic activities will have an impact on the trade between China and Africa. Using China’s trade-related data on 45 countries in Africa from 2003 to 2012 Gravity model examines the impact of the informal sector on China-Africa trade. The results show that the existence of the informal sector has hindered the development of trade between China and Africa in the short term, but the long-term impact is not significant.
