中国全行业本地市场效应实证研究——从新经济地理角度诠释扩大内需

本文重新构建Krugman(1991)核心—边缘模型,从理论研究中推导出规模报酬递增行业中本地市场效应的存在。根据全国30个地区2002年截面数据研究显示,我国42个行业中至少有11个行业存在着明显的本地市场效应,另有14个行业的超额需求系数接近于1。其中,纺织等劳力密集型行业不存在本地市场效应,我国的出口仍然是以产业间贸易为主。因此,扩大内需对于我国经济增长具有举足轻重的作用,在优化产业结构和调整出口产品结构方面具有一定的导向性。

Empirical Research on Home Market Effect of Overall Industry in China:Explanation of Expanding Domestic Demand from the View of New Economic Geography

The paper reconstructs the core-periphery model raised by Krugman in 1991,and derives the existence of home market effects in industries with increasing returns to scale from theoretical study.Using the cross-section data of 30 regions of China in 2002,it finds that at least 11 industries in all 42 industries have significant home market effects.In addition,excess demand coefficients of 14 industries approach to 1.While some labor-intensive industries such as textile industry have no home market effects,mos...
