Research On Interregional Input-output Model Based On Spatial Linkage Of The Jingjin-regional Economies

Doubtlessly, the potential of the Bohai Delta's economic development is huge. Beijing and Tianjin are the hard-core of the Bohai Delta. The cooperation of the two cities has played a critical role of speeding up the Bohai Delta's economy growth. Except for the self-improvement, the development of regional economy depends on the interregional cooperation. In order to improve the industry structure and the technology level and benefit the region economy growth, Beijing and Tianjin should strengthen the trade exchanges of production-stuff and goods with other regions. It is the introducing of the spatial concept into the regional economics that illustrate the research of the regional economics. Therefore we use the methodology of Input-Output analysis to research on the spatial linkage of multi-regional economies so as to put forward some sound suggestions on the improvement of the interregional cooperation.To begin with, we study the theory of Interregional Input-output Model Based on Spatial Linkage of the Multi-regional Economies.Secondly, this article makes an empirical analysis on the level of the influence of interregional economy and some critical industries and discusses the economic meanings of the two important measures of the interregional multiple effect, the spillover effects and feedback effect.Moreover, on the basis of the analysis of the level of interregional feedback effect, we explore the feedback loops and interregional hierarchies of China spatial economic structure and make a brief conclusion on the different characters of the feedback loops.Finally, we tried to put forward to some policy suggestions on the basis of the characters of the feed back loops so as to promote the cooperation of Beijing and Tianjin and other regions.
