边际地区边际化机制解析——古浪县、宁海县的实证研究

区域差异与空间非均衡一直是地理学关注的核心问题之一,空间经济非均衡发展中的空间边际化是空间极化与空间边际化耦合作用的结果.文章建立了四大作用力、四种效应、四个测度分量的理论分析框架,基于古浪县农民人均纯收入数据进行了实证分析.研究表明:内部边际化是导致边际地区空间边际化差异的主要原因,农业发展的自然环境和灌溉条件起着关键性作用;受自然环境及其弱化的经济环境的双重约束,内部边际化以一种持恒的力量阻滞着边际地区的内生增长,并具有难以逆转的刚性特点;外部边际化是驱动边际地区与发达地区农民收入差距扩大的主要动因;在经济全球化、经济转型、多级城市经济极化背景下,不同地区非农产业发展环境和发展水平迥然不同,中国空间经济呈现出持续而强烈的梯度差和边际化特征.

Research on marginal mechanism in marginal region: Case study of Gulang County and Ninghai County

Regional disparity and unbalanced spatial distribution is the core issue in geography, the marginalization of unbalanced spatial economy development is due to spatial polarization and spatial marginalization. In order to deconstruct the marginal mechanism of marginal region, a theoretic analysis framework which includes four forces, four effects and four measure components is set up, and an empirical analysis on rural per capital net income is made. Firstly, the natural environment and irrigation condition are the main reasons of the internal marginalization of marginal region. Secondly, the development of marginal region is blocked by internal marginal force with irreversible rigid feature, because of the double restrict of natural and weak economic environment. Thirdly, external marginalization is the main reason that widens the gap of peasant''s income between marginal region and developed region. Finally, under the background of economic globalization, economic transition and economic polarization of multi-level city, there are big differences of the develop environment and developing condition of nonfarm economy between different regions, thus presents the feature of persistent and strong gradient difference and marginalization of spatial economy in China. Furthermore, the future research issues and directions in this field are addressed.
