【摘要】：新经济地理学是由鲁格曼(Paul Krugman)提出，核心观点是以规模经济、报酬递增和不完全竞争的假设前提来代替传统的报酬递减与完全竞争的假设，，因而对传统西方经济地理学提出了极大的挑战。新经济地理学关于经济活动的空间集聚核心内容主要集中在报酬递增、空间集聚和路径依赖三个方面。专业化、多样化的分析研究归根结底是关于集聚经济的研究。以往关于产业集聚发展的经验研究很多，而本文试图通过产业专业化、多样化的视角进一步丰富产业集聚发展的理论研究体系。基于前人的研究，本文通过理论构建了专业化、多样化与劳动生产率之间的相互作用关系，并运用空间计量经济学方法对2007-2012年广东省21个地区的面板数据进行实证分析。研究表明：（1）广东省各个地区劳动生产率之间存在空间依赖性和空间异质性，并且空间计量模型中的SEM模型和GWR模型更适合研究外部性与区域经济发展的关系；（2）专业化外部性、就业密度对劳动生产率具有正向促进作用，但专业化外部性对劳动生产率的作用程度会受产业性质以及地区的影响。第一产业专业化外部性与第三产业专业外部性对劳动生产率的作用程度高于第二产业专业化外部性；珠三角地区第三产业专业化水平对劳动生产率作用显著，而广东东西翼地区和广东山区第二产业、第三产业专业化水平的提高则有利于该区域劳动生产率的提高；（3）产业多样化水平对劳动生产率的作用效果不显著。这可能是由于多样化程度与产业增长之间存在着非线性关系；（4）珠三角地区的城市规模对于该区域的劳动生产率的作用效果不明显，而广东省东翼、西翼以及广东山区的城市规模对于该区域的劳动生产率的作用为正向显著。
[Abstract]:Neo-economic geography was put forward by Paul Krugman. The core idea is to replace the traditional assumption of diminishing and complete competition with the assumptions of economies of scale, increasing returns and incomplete competition. Therefore, it poses a great challenge to the traditional western economic geography. The core contents of the spatial agglomeration of economic activities in Neo-economic Geography are mainly focused on three aspects: increasing returns, spatial agglomeration and path dependence. The analysis and research of diversification is, in the final analysis, the research on agglomeration economy. There are a lot of experiences about the development of industrial agglomeration in the past. Diversification perspective further enriches the theoretical research system of industrial agglomeration development. Based on the previous studies, this paper constructs the interaction between specialization, diversification and labor productivity through the theory. The panel data of 21 regions in Guangdong Province from 2007 to 2012 are analyzed by using spatial econometrics. The results show that there is spatial dependence and heterogeneity among labor productivity in different regions of Guangdong Province. The SEM model and the GWR model in the spatial econometric model are more suitable to study the relationship between externality and regional economic development. The employment density has a positive effect on labor productivity. However, the effect of specialization externality on labor productivity is influenced by the nature of industry and the region. The externality of specialization in primary industry and tertiary industry has higher effect on labor productivity than that of specialization in secondary industry. The specialization level of the tertiary industry in the Pearl River Delta region plays a significant role in labor productivity, while the secondary industry in the east and west wings of Guangdong Province and in the mountainous areas of Guangdong Province, The improvement of the specialization level of the tertiary industry is beneficial to the improvement of labor productivity in the region. (3) the effect of industrial diversification level on labor productivity is not significant. This may be due to the existence of a relationship between the degree of diversification and the growth of industry. The effect of urban scale in the Pearl River Delta on labor productivity is not obvious. However, the urban scale in the eastern, western and mountainous regions of Guangdong Province has a positive effect on the labor productivity of the region.
