摘要
进入信息时代,信息化的不断推进正加速改变区位理论中过于依赖运输成本或劳动力成本的区位指向,产业区位的“运输指向”和“劳动力指向”逐步转为“信息指向”,信息化逐渐成为企业区位选择的核心因素之一,信息活动区位及其对经济活动区位的影响也由此成为破解区域发展不均衡的焦点。在新经济地理学“中心——外围”模型框架下建立三部门、两要素的空间D-S模型,分析由信息活动所引起的经济活动地理空间区位布局,就信息部门份额与信息边际投入变动对制造业外迁与回流所起的作用进行实证分析意义重大。研究发现,信息部门的出现,以及将信息作为生产要素参与到生产过程后,制造业部门的区位分布发生明显改变,信息部门份额的变动以及信息边际投入的提高或降低均能显著影响制造业的外流与回流。
In the information age,informatization promotion is accelerating the change of location theory,which is too dependent on transportation cost or labor cost.The“Transport Orientation”and“Labor Orientation”of industrial location gradually have turned to“Information Orientation”,and informationization gradually became one of the core factors for enterprise location selection.The location of information activities and its impact on economic activity location has become a theoretical problem that needs to be solved urgently.This paper establishes a three-sector,two-element Spatial D-S Model under the framework of the Core-peripheral Model,analyzes the geographic space location layout of economic activities caused by information activities,and conducts a model analysis on information sector share change and information marginal input change’s influence on the offshore and back-flow of manufacturing.It shows that after the emergence of the information sector and the participation of information as a production factor in the production process,the location distribution of the manufacturing sector has changed significantly.The change in the information sector share and the increase or decrease in the marginal input of information can significantly affect manufacturing.
