区域外部性的基础理论及其研究意义

The Theoretical Basis and the Research Significance of Regional Externalities

当前国内外关于区域外部性研究比较零散,尚缺乏一套行之有效的理论体系。据此,从区域外部性存在的充要条件、理论基础、研究内容和研究意义等方面进行了系统梳理。研究结果表明,区域性与区域差异性、区域关联性和区域作用的单向性是其存在的充要条件,区域空间关联理论、地理运动理论、公共规制理论等是其分析的理论基础;区域外部性的基本内涵、主要表现形式、地理运动格局、作用机理、内化途径等是其主要研究内容;至于区域外部性问题的研究意义,认为在全球变化问题上,区域关系是焦点问题和热点问题,区域外部性研究是揭示区域关系的一个重要的认识工具,是对地理学区域研究的发展,其将丰富和发展地理学的空间相互作用理论,对促进我国的区域协调发展具有重要的实践意义。

Based on the current study of regional externalities both in domestic and foreign, this article made a systematical combing from the aspects of the necessary and sufficient condition, basic theories, research contents of the regional externalities and its research significance. The results show that the regional differences, the regional interaction and the one-side directivity are the necessary and sufficient condition of the regional externalities ; while the research contents of regional externalities refer to its basic connotation, the main manifestation, the pattern of the geography movement about the surface material, the mechanism of the regional externalities formation, the ap- proach of internalization and the internalization of the theory analysis; As to the research significance, this article makes a conclusion that the research of regional externalities has an obvious scientific significance. In the global change issues, the regional relationship has become the focus and hotspot issues; It is an awareness tool to reveal the regional relationship, a development of regional study in geography , which will enrich and develop regional in- teraction theory in the field of geography studying, also has important practical significance to promote coordinated regional development in China.
