金融业的一个重要特征是金融集聚。本文基于2010-2020年我国31个省的面板数据,通过计算全国金融业的莫兰指数来确定金融三大产业银行业、保险业和证券业集聚的空间依赖性,运用空间杜宾模型研究金融集聚对收入增长溢出效应的区域异质性。结果表明,银行业集聚对三大区域收入增长的空间溢出效应显著为正;保险业集聚存在对东部地区与中部地区正向的收入溢出效应,对西部地区的溢出效应显著为负;证券业集聚存在对东部与西部地区负向的收入溢出效应,对中部地区的溢出效应为正但不显著。因此,差异化的政策引导与区域间协调的金融资源配置对区域收入稳定增长意义重大。 相似文献

云南省经济空间结构正处于核心—外围二元结构的空间演化阶段,集聚尤其是中心城市集聚占主导地位,但有向外扩散的趋势。要注意协调好核心地带与其他地区的关系,发展相互间的经济技术合作,在重点发展核心地带的同时,充分发挥核心地带的扩散作用,带动全省经济社会的全面进步。 相似文献

随着我国社会经济的不断发展,城市本身也在向前发展.然而我们的城市景观,在这种迅猛发展的过程中,正逐渐丧失其地域性和文化性的特色,趋向雷同.本文针对当前国内城市景观设计中普遍存在的文化失语现象,提出应该对城市景观空间进行整合;并在继承优秀传统文化同时,还需引进先进设计理念. 相似文献

This article details the evolving social and spatial dynamics of a planning approach that is now being used to regulate irregular or informal settlements in the conservation zone of Xochimilco in the Federal District of Mexico City. As part of the elaboration of ‘normative’ planning policies and practices, this approach counts, maps and then classifies irregular settlements into different categories with distinct land‐use regularization possibilities. These spatial calculations establish a continuum of ‘gray’ spaces, placing many settlements in a kind of planning limbo on so‐called ‘green’ conservation land. The research suggests that these spatial calculations are now an important part of enacting land‐use planning and presenting a useful ‘technical’ veneer through which the state negotiates competing claims to space. Based on a case study of an irregular settlement, the article examines how the state is implicated in the production and regulation of irregularity as part of a larger strategy of spatial governance. The research explores how planning ‘knowledges’ and ‘techniques’ help to create fragmented but ‘governable’ spaces that force communities to compete for land‐use regularization. The analysis raises questions about the conception of informality as something that, among other things, simply takes place outside of the formal planning system. 相似文献

The issue of what to promote in total factor productivity (TFP) in urban areas has been widely discussed in academia and housing prices and population density are confirmed to be two of the most essential driving factors. However, research into the interaction of housing prices and population density with TFP has been neglected, with no previous studies taking spatial factors into consideration, which may bias the results. From this perspective, using spatial panel data models and employing instrumental variables to solve the endogenous problem, this study examines the impact of housing prices on TFP through the mediating effect of population density for 283 Chinese cities during the period 2000–2013, and confirms that the mediating effect accounts for 18.70 % of the total effect. The results show the positive and significant association of housing prices with TFP and the inverted U-shape of population density. The underlying logic is that housing prices change population density by attracting people with high purchasing power and discouraging those unable to afford housing, whereas increased density helps to promote productivity since the settled inhabitants always have highly developed work skills and are well educated. The influencing mechanism of housing prices on TFP through population density is analyzed, namely the spillover effect. We find that the spillover effect exists in the eastern and central regions, as well as first, second, and third tier cities, while for western regions and fifth tier cities, population mobility and increased in housing prices slows their economic development. There is no evidence of any spillover effect in fourth tier cities. A discussion and suggested policy implications are also provided. 相似文献

利用2006-2017年长三角城市群和长江中游城市群共41个地级市面板数据,首先,运用拓展DEA法对两大城市群协同创新水平进行测度,然后,采用空间计量模型实证考察创新要素流动对城市群协同创新的影响,进一步以互联网发展水平为门限变量,构建门限模型,探析互联网发展对创新要素在城市群流动的协同创新效应是否存在门限效应。研究发现:创新要素流动对城市群协同创新影响的总效应显著为正,空间正向溢出效应显著,且存在群际差异;在两大城市群内,创新要素流动对城市群协同创新影响呈现非线性,创新人员流动对城市群协同创新影响呈“倒U型”特征,创新资本流动对城市群协同创新影响呈“U型”关系,相应拐点在不同城市群呈现异质性。 相似文献
