行政区划作为国家治理体系的基础支撑,对区域经济发展具有重要影响。深入探究行政区划与区域经济的时空耦合关系与优化路径,有助于制定区域一体化发展政策。本文以成德绵地区为例,基于政区位势模型、行政区经济模型和位序规模理论,定量识别2005—2018年政区位势与行政区经济的耦合与空间演变,并从体制机制改革、行政区划调整等角度提出优化路径。研究表明:① 成德绵地区政区位势和行政区经济分别经历了“沿交通线轴向扩散”和“中心极化-中部辐射递减-外围塌陷”的演化过程。② 根据政区位势位序规模相对于行政区经济位序规模的耦合关系,将政区耦合类型划分为位势靠前、区划适应型,位势靠前、区划约束型,位势落后、区划适应型,位势落后、区划约束型。③ 研究区耦合类型表现为“位序落后型收缩-区划适应型增加-位势靠前型主导”的演变特征,位势靠前、区划约束型占比最高(45.0%),市辖区和北部外围政区发展潜力大幅提升的同时,三市交界处行政区经济约束相对较强。成德绵地区作为中国西部地区的重要增长极,未来应结合不同政区类型的实际情况,通过增强政府间合作、充分利用中心城市的辐射带动效应、转变政府职能和审慎稳妥推行行政区划调整工作等方式,促进区域一体化和城市群经济高质量发展。  相似文献

The relationship among the population, economy and water resources is complex, and the contradictions and conflicts will appear and aggravate with the rapid development of economy and society in Northeast China. Based on the statistical analysis of the available data, this paper depicted the static distribution characteristics of the population, economy and water resources of Northeast China in 2011. It was found that the spatial distribution of the population, economy and water resources was unbalanced in Northeast China. The water resources mismatched with the population and economy. The population and economy were relatively dense and developed in the southwestern part of Northeast China respectively, while the water resources was relatively scarce. However, the situations in the northern part of Northeast China were opposite to those in the southwestern part. The population-economy inconsistence indexes of the cities in northern part of Northeast China showed a significant trend of spatial aggregation and heterogeneity. The cities with lower (<1.5) and higher (>1) inconsistence indexes all faced the problem of water resources shortage. Applying geometric gravity center method and grey correlation model, the result indicated that there was relatively high spatial relevance and the relative deviation among the spatial dynamic distributions of the population, economy and water resources was large. The gravity centers of economy and per capita average annual total water resources moved westward, while the gravity center of population gravity center moved eastward in the period of 1997–2011 in Northeast China. It must be noted that, the migration trend of the economy gravity center was more significant than those of the population and water resources.  相似文献

通过对沅江市杨树生产的初步研究,着重讨论了杨树生产对沅江市区域经济和生态环境的影响。通过研究发现:大面积种植杨树能有效抑制钉螺的生长和繁殖,在一定程度上控制血吸虫病蔓延;带动当地家具业等相关产业的发展,提高了当地居民的收入;对当地居住环境的改善,防洪治水有着积极的意义。同时,大面积种植单一树种,也对湖区的湿地环境产生了一系列的不良影响。  相似文献

随着经济发展的资源和环境约束日益突出,发展循环经济,建设资源节约型和环境友好型社会成为中国可持续发展战略不可分割的组成部分。国际上,循环经济已由最初的理念逐步被推向实践,成为构建新型经济模式的重要手段和途径。本文在回顾发达国家循环经济发展历程的基础上,从制度供需及制度主体角色定位的角度概括其在发展循环经济的主要经验。最后比照中国循环经济的发展实践,指出中国循环经济发展中的制度缺陷。  相似文献

This paper proposes a new theory of value based on the observation of how people use this term. In everyday life the word value is commonly used to refer equally to what might be regarded as the incommensurable polarity between value as price, and value as priceless, sometimes portrayed as the contrast between value and values. My theory starts from trying to learn how people manage to use value as a means of bridging this divide. As such it opposes itself to ‘bottom-line’ theories of value. These range from vulgarised forms of Marx’s labour theory of value, to the way management consultants tried to impose a universal belief in shareholder value. An example is provided of how such bottom-line thinking undermined a UK government audit called best-value, and is also found in highly reductionist attempts to impose new-age values in management. By contrast, examples are given of how value is created in the process of bridging the divide between value and values, starting from the work of Zelizer and the case of concubines in 5th century BC Athens. Further examples range from the department store John Lewis to the Swedish social democratic state. Finally the application of this theory is considered in relation to a recent attempts to evaluate the impact of the mobile phone on low-income Jamaicans.  相似文献

Environmental economic geography: A sympathetic critique   总被引:4,自引:0,他引:4  
Gavin Bridge 《Geoforum》2008,39(1):76-81
In this article I examine the objectives and substantive claims of a body of work that has come to be known as ‘environmental economic geography’ (EEG). I characterize this loose grouping of research activities as a topical contrivance: often what unites EEG researchers is simply a desire to apply the theories and methods of economic geography to environmental issues. The article explores an alternative rationale for doing EEG: the development of a distinctive intellectual project out of the encounter between economic geography and environment. Such a project extends beyond an assessment of the environmental impacts of economic activity, to examine the ways in which many ‘economic’ processes are environmentally constituted.  相似文献

1 Introduction For the two past decades of economic reforms in China, the urbanization level has risen dramatically from 17.92% in 1978 to 41.8% in 2004, with the average an- nual increase in the urbanized population of 3.3%. Owing to the social and economic factors, however, the agri- culture, rural area and farmer, named “three agricul- ture-related problems” in the country, have benefited little from the rapid and unprecedented process of ur- banization (Lin and Ho, 2003). Conversely, as…  相似文献
