摘要
本文基于区际贸易的视角,通过建立多地区多产业的李嘉图模型首次系统研究了国内市场分割对中国区域发展不平衡的影响。本文将国内市场分割的成因区分为地方保护和运输成本,并基于模型估计出地方保护和运输距离对市场分割的影响。数值模拟分析表明,在中国区域发展不平衡的成因中,市场分割至少是和传统的资本禀赋差异、技术差异同等重要的因素,降低市场分割程度能有效解决区域发展不平衡问题。在通过降低地方保护水平促进区域发展平衡时,应注意大幅降低落后地区的地方保护程度;通过改善交通基础设施来降低运输成本也能起到促进区域发展平衡的作用。另外,缩小地区间资本禀赋和技术差异并不总是能促进区域发展平衡,在采取政策手段时,应该定位于大幅提升落后地区和中等收入地区的资本禀赋和技术水平。
This paper studies the impact of domestic market segmentation on the unbalanced regional development in China by establishing a multi-region and multi-industry Ricardian model from the perspective of interregional trade.The origin of domestic market segmentation is differentiated into local protection and transportation cost,and the influence of local protection and transportation distance on market segmentation is estimated based on the model.In the cause of unbalanced development in China,market segmentation is at least the same as the traditional capital endowment difference and technical difference,and reducing the market segmentation can effectively solve the imbalance of regional development.In order to promote regional development balance by reducing the level of local protection,attention should be paid to reducing the degree of local protection in backward areas,and reducing transport costs through improved transport infrastructure can also play a role in promoting regional development balance.In addition,the narrowing of regional capital endowments and technical differences does not always contribute to the balanced development of regions,and in adopting policy instruments,it should be located in raising the capital endowment and technical level of backward and middle-income areas.
