区域二重开放下的产业空间演进研究

产业的空间演进是产业为了实现利润最大化而对其空间区位进行选择及变换的过程.基于区域二重开放的经济现实,在新经济地理学分析框架之下构建两国三区域模型,比较垄断竞争条件下企业在各个区位的收益,推导出企业空间区位演变的判决条件,进而构建产业空间区位演进系统.分析表明:企业是否进行空间区位变换取决于其区位变换带来的收益与成本能否使企业实现利润最大化,而影响该收益与成本的关键因素则是贸易自由度、区域内的要素成本等区位因素.因此,一国政府可以通过调整和控制国家间以及区域间的贸易自由度来引导外商以及国内企业的区位演变,尤其是对于具有低工资优势的地区而言,加大该地区与国内其他具有高开放度地区之间的区际开放度,或者提升其直接对外贸易的开放度,都有利于吸引区外产业进驻该地区.

Research on the Industrial Space Evolution in Location Dual-open-economy

Industrial space evolution is the process of its space location selection and transformation to realize profit maximization. Based on the economic realization of regional dual-open-economy, under new economic geography analysis framework, a two-country-three-zone model has been constructed, the earnings of the enterprises at each location under the condition of monopoly competition is compared, the judging condition of space location evolution of the enterprises is derived and furthermore industrial space location evolution system is built. The analysis shows whether the enterprises can conduct space location transformation depends on whether the benefit and cost from their location transformation can make the enterprises realize profit maximization, however, the key factors affecting the benefit and cost are trade freedom degree, the factors and cost in the location and so on. Thus, the government of a country can guide the location evolution of foreign companies and domestic enterprises by regulating and controlling trade freedom degree, especially for those locations in which the workers earn low salaries, enlarge the open degree between the location and the location which has high open degree or raise its direct foreign open degree, all of which is conducive to attracting the enterprises to stay in the locations.
