资源约束下两区域的增长

多区域增长溢出与资源约束下的可持续发展是区域增长研究领域两个非常重要的课题,但是,多区域增长溢出的研究往往忽略了资源的约束,而可持续发展研究往往缺少了对多个区域的考虑。论文将区域增长、资源贸易以及资源开发的溢出等因素结合起来,构建了两区域的增长模型,其中一个区域出售部分自身资源,另一个区域利用其他区域资源。在模型基础上,论文通过调整模型各参数进行了模拟分析,研究发现在区域内部技术溢出不足时,落后区域适合出售资源,在区域内部技术溢出很强烈的情况下,落后区域将资源投入生产比出售资源获得的收入大。两区域经济系统通过调整区域出售资源的比例,可以获得双赢的结果。

A Simulation to Economic Growth of Two-Region under Resources Restriction

Multi-regional growth spillover and sustainable development subject to resource limits are two important problems in regional growth study.Many models were developed in these two fields. But resources restriction was ignored in the study on the multi-region growth spillovers and report on the study of sustainable development considering of multi-regions is seldom seen. In this article,a two-region growth spillovers model is built for the study of this problem in terms of regional growth,resources development and resources trade. In the model, one of the two regions sells part of its resource to the other region.The parameters of the model are altered to analyze the outcomes of the two regions respectively.It is found that it is better to sell natural resource for the relatively backward region when the FTP is slowly.However, the relatively backward region will achieve more income by inputting its resources to production than by selling them when it has strong internal knowledge spillover.It is also found that the two regions can both get positive spillover through resource trade if the ratio is set carefully.Regional growth spillover and sustainable development problem in growth study are reviewed in the first section of the paper.Models are given in the second part.In third section the impact of parameters alteration on both regions are studied in detail.Discussions and conclusions are given in the fourth part.
