摘要
自20世纪90年代以来,藤田、克鲁格曼、维纳布斯等以迪克西特和斯蒂格利茨垄断竞争模型为基础,用不完全竞争、报酬递增和市场外部性等理念构建新的经济地理模型,掀起了一场“新经济地理学”革命。新经济地理学在理论基础、研究特点和方法等方面与传统经济地理学表现出明显不同,其理论创新受到经济学界和地理学界的普遍关注。但是,也有一些学者对它提出了同样引人注目的抨击。通过对新经济地理学与传统经济地理学进行比较,对一些重大理论假设、研究方法与特点进行简要分析,有助于廓清对新经济地理学与传统经济地理学之异同的正确认识,以期推动新经济地理学的理论研究与应用以及新经济地理学与传统经济地理学领域的学术交流。
From 1990s onwards, Fujita, Krugman and Venables et al. use conceptual tools of imperfect competition, increasing returns and pecuniary externality to construct theoretical models of new economic geography on the basis of Dixit-Stiglitz framework of monopolistic competition, which leads to a revolution of new economic geography. In terms of theoretical roots and research method, new economic geography exhibits noticeable difference from traditional economic geography. Its theoretical innovation attracts attention from academic circles of both economics and geography. However, new economic geography has been under severe criticism even since its emergence. While some criticism makes academic sense, unfortunately, owing to a lack of full understanding of the theoretical rationale of new economic geography, other criticism actually misses the point. This paper aims to making a comparative study of new economic geography and traditional economic geography in terms of theoretical assump- tions, research methods and their respective features. It is hoped that the discussion here will contribute to a clear understanding of the differences as well as similarities between new economic geography and traditional economic geography, which may forward the further research in and application of new economic geography as well as communication between circles of new economic geography and traditional economic geography.
