社区变迁对区域经济的影响分析

社区变迁影响着区域经济的发展,社区在发展过程中所形成的固有优势影响着社区的进一步发展,社区的规模和制度创新引导着资源向城市、社区的流动,资源流动和资源优势使区域经济发展出现新的格局,区域经济的发展依赖于城市群经济和海洋经济的发展。     

长株潭"3+5"城市群产业目标结构研究

通过对长株潭"3+5"城市群产业结构现状与同等收入水平的国际"标准"产业目标,发现长株潭"3+5"城市群的产业结构现状与国际"标准"产业目标结构差距较大,国际"标准"产业目标结构不宜作为其产业调整的近期目标结构.最后,结合长株潭"3+5"城市群内各市的发展现状,制定了各市产业调整的近期目标结构.

Spatial externalities and agglomeration in a competitive industry

We introduce spatial spillovers as an externality in the production function of competitive firms operating within a finite spatial domain under adjustment costs. Spillovers may attenuate with distance and the overall externality could contain positive and negative components with the overall effect being positive. We show that when the spatial externality is not internalized by firms, spatial agglomerations may emerge endogenously in a competitive equilibrium. The result does not require increasing returns at the private or the social level, increasing marginal productivity of private capital with respect to the externality, or location advantages. In fact agglomerations may emerge with decreasing returns to scale, declining marginal productivity of private capital with respect to the externality, and no location advantage. The result depends on the interactions between the structures of production technology and spatial effects as shown in the paper. No agglomerations emerge at the social optimum when spillovers are internalized and diminishing returns both from the private and the social point of view prevail. Numerical experiments with Cobb–Douglas and CES technologies and an isoelastic demand confirm our theoretical predictions.     

Entrepreneurship: The Role of Clusters Theoretical Perspectives and Empirical Evidence from Germany

This paper is about the impact of clusters on entrepreneurship at the regional level. Defining entrepreneurship as the creation of new organisations and clusters as a geographically proximate group of interconnected firms and associated institutions in related industries, this paper aims to answer three research questions : first, do clusters matter to entrepreneurship at the regional level? Second, if clusters are associated with different levels of entrepreneurship, what explains those differences? Third, what do the answers to the previous questions imply for academics and policy makers? To answer these questions, this paper distinguishes between clusters and industrial agglomerations and advances a theoretical model and empirical research to explain the impact of clusters on entrepreneurship at the regional level. This paper uses the 97 German planning regions as units of analysis to test the hypotheses. Using hypotheses testing and OLS fixed-effects model, this paper finds that clusters do have an impact on entrepreneurship at the regional level, but industrial agglomerations do not. Implications for academics and policy makers and suggestions for future research are given in the concluding section.     

BIBLIOMETRIC ANALYSIS OF THE QUANTITATIVE METHODS APPLIED TO THE MEASUREMENT OF INDUSTRIAL CLUSTERS

Literature on methods for analysing interindustry interdependence and geographical concentration of firms began to multiply since the 1990s. The aim of this paper was to systematize the literature on methods and measures applied to the analysis of industrial clusters, as well as to identify trends in this knowledge field. The method used was bibliometrics, which consisted of a frequency evaluation of the publications and the relationship network between them. It was verified an exponential increase in the number of papers that composed this area, based mainly on the theories of New Economic Geography. Recently, the literature has focused on the geographic location in relation to interindustry linkages, and the frontier of knowledge has shifted from traditional methods of regional science to areas such as spatial statistics, econophysics and artificial intelligence. There are still relevant questions being explored, as Modifiable Area Unit Problem (aggregation bias), nevertheless, spatial anisotropy (directional bias) is still neglected and indicates a new research path.

中部地区城市群利用外资态势及其困境摆脱

对中部城市群2002~2009年期间利用外资的总体状况如利用外资的规模、利用外资的方式、利用外资的结构(包括来源地结构和产业结构)进行分析,设计中部城市群利用外资效率和潜力动态综合评价指标体系,在说明理论模型的基础上,采用deap2.1软件,求解Malmquist指数的DEA模型,从中部城市群整体、中部城市群内部以及核心城市三个维度进行实证分析。结果表明,必须从中部城市群整体和六大城市群自身角度考虑,提高利用外资效率和潜力水平。
