基于社交媒体的签到数据,运用社会网络分析方法,选取长三角26个地级市作为研究对象,以从百度地图获得的时间距离作为各城市间距离,结合游客微博签到数据计算了长三角城市联系网络的网络密度、中心度等指标,分析了城市联系的网络特征。同时利用2015年各城市统计年鉴数据与从百度地图获得的城市间的距离,利用经济引力模型计算了城市间的理论联系强度。以社交媒体签到数据为地区实际联系强度,以计算出的经济联系指数为理论联系强度,探讨实际联系强度与理论联系强度之间的耦合协调度,得到各城市理论与实际的协调状况,为相关决策提供支持。 相似文献

矿产资源开发与区域经济发展--关于西部大开发矿产资源战略实施的理论思考(上) 总被引：2，自引：0，他引：2
人类社会发展的历史就是一部矿产资源开发利用的历史。人类从利用石器、金属、矿物能源〔煤、石油、天然气）到今天的单晶硅，无不与矿产资源有关。但矿产资源开发利用的有关理论、模式的形成则是近一二百年的事。从古典经济学派到今天的二百多年中，伴随社会生产力的发展，经济发展理论也得到不断丰富和发展，形成了包括区位论、工业化理论、空间结构理论等在内的学科体系。目前大致可分为两大类：一是与矿产资源相关的可持续发展理论，二是与矿产资源相关的区域经济发展理论。在这里重点分析介绍这两大类理论，然后结合西部矿产资源的基本… 相似文献

城市增长与土地增值的综合理论研究 总被引：11，自引：0，他引：11
陈顺清 《地球信息科学学报》1999,1(1):12-18
针对城市增长、土地增值研究上的一些观点,本文将城市增长与土地增值的综合理论研究分为四个步骤:1.研究城市增长的动力,提出向心力、离心力和摩擦力的相互作用理论;以新制度经济学理沦为支撑背景,使这三种力的分析具有坚实的微观经济基础。2.城市增长的理论研究,提出向心力驱动为主的集聚化增长,离心力驱动为主的郊区化增长与向心力、离心力、摩擦力相互作用的网络化增长三大阶段的观点。3.建立城市土地价值与增值的理论,认为土地价值是社会使用价值、经济价值和生态学价值的总和;在土地增值方面,公共增值,特别是土地利用的外部效果导致的土地增值是分析的瓶颈;利用交易费用理论系统分析土地使用的外部效果。 在前述理论基础下,以城市增长与土地增值的经典模型入手,探讨城市增长各阶段的典型土地增值模式,提出城市增长与土地增值的理论。 相似文献

Along with the development of urban economy, the growth of urban population and the increase of needs of urban society, the
suburban ecological and economic system changes constantly and profoundly in its structure and function. Intensifying the
research on structural analysis of suburban ecological and economic system is of great significance for grasping light the
laws governing the development and evolution of the suburban ecological and economic system and leading this system onto a
path of sound circle. By making comprehensive use of the cluster analysis and latent structural analysis the author attempts
to explore a new avenue of revealing the structure of suburban ecological and economic system, taking Tianjin suburbs and
counties as an example. The results obtained from the above-stated analyses show that it is entirely possible and extremely
effective to study the structure and function of suburban ecological and economic system and provide scientific evidence for
control of this system by using mathematical methods and statistical analyses. 相似文献

Based on the interprovincial panel data of 2000–2014, this paper carries out an empirical analysis on the relationship between energy abundance and economic growth to test the theoretical hypothesis of ‘resource curse' and explore its transmission mechanism for China and its three regions. The results show that, at the national level, positive correlation is present between energy abundance and economic growth, proving that the ‘resource curse' phenomenon does not exist in China as a whole. Moreover, material capital input, human capital input and the level of opening to the outside world could promote economic growth, while technology innovation input may hinder economic growth. As seen by region, a positive correlation also exists between the energy abundance and economic growth in the eastern and western regions, and there is no ‘resource curse' phenomenon either. In all three regions, the human capital input could promote economic growth. Material capital input could promote economic growth in the eastern but hinder economic growth in the western region; the level of opening to the outside world could promote economic growth in the eastern region. It is known through further survey and analysis on the transmission mechanism of resource curse that, at the national level, material capital input, human capital input, and the level of opening to the outside world present positive correlation with energy abundance, indicating that energy development becomes an important transmission factor by strengthening material capital input and human capital input and raising the level of opening to the outside world. However, technology innovation input presents negative correlation with energy development. As seen by region, both the material capital input and human capital input present positive correlation with energy development strength in the three regions. Similar as the eastern region, the level of opening to the outside world presents positive correlation with energy industry development in the middle and western regions; however, the energy development presents negative correlation with technology input level in the western region. 相似文献

The development of any analytical method should have to experience at least four stages: its initial status, growth, mature and declining. However, although the regional input-output analysis has been widely applied for more than forty years, it is still one of the most important approach in regional economic analysis and forecast at present in the world. This is due to the never ended modifications and its great potentials. In this paper, we review the historical development of the regional input-output analysis. 相似文献

As one kind of organizational relation of regional space, in essence, urban system is the spatial reflection of the deep social economic movement.(HERZOG,1991). Since the 1980s, by means of the globalization of economy and high technology and the particular spatial effect, the evolution of urban system has taken on one brand-new landscape different from the traditional one, which also raise new concepts and requirements for urban system planning. Meanwhile, it′s no doubt that active plannin… 相似文献

To meet the challenge of sustainable development, sustainability must be made. Ecological network analysis(ENA) was introduced in this paper as an approach to quantitatively measure the growth, development, and sustainability of an economic system. The Guangdong economic networks from 1987 to 2010 were analyzed by applying the ENA approach. Firstly, a currency flow network among economic sectors was constructed to represent the Guangdong economic system by adapting the input-output(I-O) table data. Then, the network indicators from the ENA framework involving the total system throughput(TST), average mutual information(AMI), ascendency(A), redundancy(R) and development capacity(C) were calculated. Lastly, the network indicators were analyzed to acquire the overall features of Guangdong's economic operations during 1987–2010. The results are as follows: the trends of the network indicators show that the size of the Guangdong economic network grows exponentially at a high rate during 1987–2010, whereas its efficiency does not present a clear trend over its whole period. The growth is the main characteristic of the Guangdong economy during 1987–2010, with no clear evidence regarding its development. The quantitative results of the network also confirmed that the growth contributed to a great majority of the Guangdong economy during 1987–2010, whereas the development's contribution was tiny during the same period. The average value of the sustainability indicator(α) of the Guangdong economic network was 0.222 during 1987–2010, which is less than the theoretically optimal value of 0.37 for a sustainable human-influenced system. The results suggest that the Guangdong economic system needs a further autocatalysis to improve its efficiency to support the system maintaining a sustainable evolvement. 相似文献
