中文摘要：

本文利用“义乌商圈”核心层8个区域1996～2006的相关数据进行的分析和计算结果表明：在不同区域共享一个大规模市场的条件下，由于市场不断拓展所产生的投资协同以及由此引致的规模报酬递增，导致相关区域基于各自的比较利益更容易围绕市场形成有效的分工。在市场拓展和区域分工的相互作用之下，随着市场所在地产业的向外转移和扩散，区域间的经济会向收敛的方向发展。

英文摘要：

Based on the data of eight core region in ＂Yiwu Business Circle＂, this paper studies the regional economic convergence and the results are as follows： in the condition of sharing a large-scale market among different regions, it is easier to create an effective division of labor around the regional market based on their comparative advantage because of investment synergies and the following increasing returns generated by the continuous expansion of the market. With the outward transfer and proliferation of industries, the regional economy would develop towards the convergence under the interaction effect of market expansion and regional division.
