新经济地理理论强调经济规模是地区贸易和国际贸易的驱动力,这种力量被克鲁格曼称为“本土市场效应”(home market effects)。本文直接从Fujita,Krugman and Venables(2000)一文中推导出经验检验模型,并把该模型与Davis and Weinstein(1996,1999)中的经验检验模型联系起来。使用这两个模型和中国1997年31个省(市、区)19个产业的生产、需求和资源禀赋资料,本文检验了中国各省生产和贸易类型到底是由比较优势决定还是由本土市场效应决定的问题。我们发现本土市场效应在决定中国地区间生产和贸易的类型上起着显著的作用。分产业的分析发现19个产业中至少有7个存在显著的本土市场效应。
The new economic geography theory emphasizes that the economic size is the driving force for regional trade and international trade, a force Krugman calls “home market effects.” In this paper, an empirical test model is derived directly from Fujita, Krugman and Venables (2000) and linked to the empirical test model in Davis and Weinstein (1996, 1999). Using these two models and the data of production, demand and resource endowment of 19 industries in 31 provinces (municipalities and districts) of China in 1997, this paper examines whether the production and trade types in various provinces of China are decided by comparative advantage or by local market effect The problem. We find that the local market effect plays a significant role in determining the types of production and trade in China. An analysis by industry shows that at least 7 of the 19 industries have significant local market effects.
