This study focuses on China's coastal area and its marine economic development. Applying the information diffusion method, the study establishes a kernel density function and its decomposition using a marine economic per capita as the index of the model to depict the dynamic evolution law and the internal influential factors of the Chinese marine economy during 1996–2013. The relative development rate was introduced to analyze the spatial differences in the marine economy's development. In this way, space and time dimensions fully characterized the evolution of the Chinese marine economy. Additionally, the influence of growth and inequality in the process of its development can be analyzed. The study shows that the Chinese marine economy as a whole has been growing, and regional marine economic development is relatively coordinated. In addition, the marine economy began to develop even more rapidly after 2004. There are three factors affecting the dynamic evolution of China's marine economy: first, the most influential mean effect, followed by, second, the variance effect, and third, the least influential residual effect. The biggest influence on the dynamic evolution of the marine economy is the improvement of the development level of the marine economy in the coastal area. Meanwhile, due to the existence of inequality, provinces at higher development levels are more dispersed. Furthermore, the existence of the residual effect weakens the influence of the mean effect, and the influence on the dynamic evolution of the marine economy continuously increases. In the analysis of the influencing factors of the evolution and spatial difference of marine economic development, the level of opening to the outside world, the level of investment in fixed assets and the industrial structure have a positive role in promoting economic development. However, capital investment in scientific human research has a negative correlation with economic development, and does not pass the significant test. The difference in regional development levels and development speed is also very apparent; namely, the provinces with higher development levels generally displayed faster development speeds while those with lower development levels showed slower development speeds across the four periods analyzed.  相似文献

1 Introduction Northeast China consists of the three provinces of Heilongjiang, Jilin and Liaoning. Since the founding of the People's Republic of China in 1949, this region has supported the whole country with huge quantity of grain, raw materials, primary products, and heavy industrial products at the cost of environment and resources, and thereafter became an old industrial base as well as an important marketable grain base in the whole country (Zhang et al., 2004). However, since the 19…  相似文献

The types of operation play a key role in facilitating tourism consumption and economic development in a tourism destination. By adopting evolutionary economic geography theory, the paper analyzes the types of operation in West Lake Scenic Area from 1978 to 2013. First, an evolution process consisting of four stages is underpinned, and they are: the new establishment stage, the preliminary development stage, the speedup development stage, and the stabilized maturity stage. Specifically, the distinct characteristics associated with operation types are compared and evaluated at different stages throughout the process. The evolution trees are introduced to scrutinize types of operation development. The results of evolution trees demonstrate the substantial increase in both numbers and types. Second, by applying GIS spatial analysis, the paper also analyzes the spatial evolution characteristics on the types of operation, and the results unveil the co-existence of centripetal and centrifugal forces: the processes of spatial agglomeration and spatial dispersion. More specifically, we recognize the spatial process includes the emergence of node and concentration(1978–1995), the sparse distribution and intensity reduction(1996–2002), the patchy distribution and spatial agglomeration intensification(2003–2008), the dispersed distribution and core area agglomeration(2009–2013). Lastly, path dependence on resource endowment, government and market innovation, knowledge learning and spillover can reasonably explain the types of operation evolution. In conclusion, the evolutionary economic geography theories provide new theoretical and empirical perspectives for tourism policy analysis. At the same time, our comprehensive evidences impart more comprehensive insights and offer useful managerial and policy implications.  相似文献

With rapid urbanization process, the pace of urban sprawl has been quickened and most metropolises have experienced expansions in leaps and bounds in suburbanization, which has greatly changed the urban and rural spatial structure of the metropolis fringe area. In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spatial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migration, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for carrying out spatial management and development planning of metropolis fringe area.  相似文献

The relationship between China’s urbanization and economic development(RCUED) is an important concern nationwide. As important actors in regional strategy and policy, county-level regions have played an increasingly significant role in the development of China’s social economy. However, the existing research on the RCUED lacks the fine depiction of the county-level administrative units.Using 2000 and 2010 census data and the statistical analysis method, we uncovered the evolution characteristics of China’s urbanization and economic development and conducted a quantitative identification for the RCUED with improved methods using the quadrant map approach. In addition, we investigated the spatial correlation effect of the RCUED using the spatial autocorrelation analysis method. The results were as follows: 1) In general, a high degree of matching exists between China’s urbanization and economic development at the county level at the significance level of 0.01. The correlation coefficients between China’s urbanization and economic development in2000 and 2010 were 0.608 and 0.603, respectively. 2) A significant regional difference exists in the RCUED at the county level. Based on a comparative analysis of 2276 county units in China in the two years, we found that county units can be categorized as under-urbanized, basic coordination and over-urbanized in various areas. No situation was observed where urbanization seriously lagged behind the economic development level, so the levels of urbanization and economic development appear to be basically coordinated,and the coordination state may be gradually optimized over time. 3) Over time, the spatial dependency of the RCUED has weakened and the spatial heterogeneity has increased. Northeast China has always been an area characterized by over-urbanization. The number of county units classified as under-urbanized has begun to decline in eastern coastal urban agglomeration areas, while counties rich in resources have transformed from having point-shaped over-urbanization to plane-shaped under-urbanization along the northern border,and the number of over-urbanized county units has increased in the middle reaches of the Yangtze River. 4)’Lag-lag’ type and ’advance-advance’ type accounted for 68% of all counties in China, and these counties were shown to have obvious spatial differentiation characteristics.  相似文献

重庆市交通网络的可达性时空特征及其演化规律   总被引：1，自引：0，他引：1  
可达性是度量区域交通网络结构通达性的有效指标。本文以1997、2001、2004、2008和2012年为时间断面,以加权平均旅行时间为指标,对重庆市陆路交通网络中节点区县可达性时空特征及演化规律进行了研究。结果表明：重庆市交通可达性总体呈现以主城区为中心向外围区域递减的“核心-边缘”模式,可达性等值线大致呈不规则环状分布;随着路网的不断完善,可达性水平由中心向外围呈圈层式优化,各区县的可达性有大幅度的提升,但不同阶段可达性提升幅度不同,第1、2阶段（1997-2004年）可达性相对第3、4阶段（2004-2012年）而言优化程度更为显著。由于可达性值变化幅度与其初始值有关,所以,边缘地区可达性值提高幅度始终大于中心地区,区县可达性差异逐渐缩小,可达性分布趋于均衡。由于空间经济分布具有明显的不均衡性,可达性与经济发展之间具有一定的互动耦合关系,交通网络的区域效应显得更为复杂。交通网络如何与城市体系合理匹配,形成良性互动的“交通-城市-经济”复合系统,是未来区域交通建设规划应该重视的内容。  相似文献

This paper examines spatio-temporal characteristics of an oasis economy and its relationship with water and mineral resources in the Turim River Basin from 1965 to 2005. A spatial autocorrelation model, the center of gravity model, and index system of the regional central city are used to probe the evolution laws of spatial structure of oasis economy. The study finds that: 1) The economic centre of gravity, whose variation track during this period follows linear rote law, was moving from headstream to middle reaches of the Tarim River. 2) Positive spatial autocorrelation which showed a waving and ascending trend of regional economy was significant and the neighbor effect of regional economic growth was strengthened continuously. 3) The regional economic centre was located in Hotan City before 1980, moved to Aksu City during the 1980s and to Korla City after 1990. We conclude that above all, during the recent four decades the evolution of the oasis economy in this region has gone through three stages: a traditional agriculture stage (before 1980), oasis agriculture and agricultural product processing stage (1980-1990) and oasis energy industry stage (after 1990). Furthermore, the dependence degree of the oasis economy on natural resources in different stages are studied by using dominance index, regression model, and grey relation method, which shows that an oasis economy highly depends on water resources in the oasis agriculture and agricultural product processing stage while it depends more on mineral resources such as oil and natural gas during the oasis energy industry stage.  相似文献

This paper aims to explore urban geography with a new perspective. Endowed with the urban geography connotations, an improved data field model is employed to integrate temporal dimension into spatial process of cities in a typical region in this article. Taking the Beijing-Shanghai Corridor including 18 cities as an example, the authors chose the city centricity index (CCI) and the spatial data field model to analyze the evolution process and features of sub-region and urban spatial interaction in this corridor based on the data of 1991, 1996 and 2002. Through the analysis, we found that: 1) with the improvement of the urbanization level and the development of urban economy, the cities' CCI grew, the urban spatial radiative potential enhanced and the radiative range expanded gradually, which reflects the urban spatial interaction's intensity has been increasing greatly; 2) although the spatial interaction intensity among the cities and sub-regions in the Beijing-Shanghai Corridor was growing constantly, the gap of the spatial interaction strength among different cities and sub-regions was widening, and the spatial division between the developed areas and the less developed areas was obvious; and 3) the intensity of the spatial interaction of Beijing, Shanghai and their urban agglomerations was far greater than that in small cities of other parts of the corridor, and it may have a strong drive force on the choice of spatial location of the economic activities.  相似文献

For almost three decades, China has been undergoing significant transition from a planned economy to a market economy. Fast-paced economic growth and urbanization, interacting with market-oriented reforms in land re- sources allocation, have caused profound spatial restructuring of Chinese cities. This paper examines urban expansion and land use reconfiguration in Shanghai’s central city from 1979 to 2002, with a special focus on the effect of the adoption of the land-leasing system in 1988. The empirical research, which employs GIS-based spatial analysis tech- niques to explore land use data for multiple years, indicates fundamental changes in the spatial characteristics of urban development in Shanghai after this important land policy reform.  相似文献

This paper meant to analyze the spatial evolution of a large country in its process of integration with the world economy in general, and, to look into the possible effect of China‘s accession into WTO on the future development of its spatial economy in particular. Through an approach of increasing returns, external economy, product differentiation and path-dependence, with foreign trade costs incurred by different regions within the large country discriminated, a model of investment and employment flow is developed as a simulation of a large country‘s process of integration with the world economy. The modeling indicates that in the process of integration, as there exist differences in foreign trade costs among different regions within the large country, either the spatial economy of the country deviates from its symmetric structure in autarky and falls into a core-periphery relationship, or the effect of industrial agglomeration is reinforced, amplified and locked in, if the agglomeration had been started. The economic gap on either the aggregate or structural basis between different regions within the large country will increase rapidly as the integration proceeds.  相似文献

都市圈的形成是自然和社会因素长期共同作用的成果,是人类文明的进步。都市圈战略是中国未来区域发展的重要战略。随着全球经济竞争日益激烈,通过调整空间结构来扩展经济效益空间是大势所趋。目前,国内掀起了规划建设都市圈的热潮。然而,从世界都市圈发展的经验和教训来看,人口、经济发展集中于沿海超大城市的现象越来越突出,反映出地区经济发展的不平衡和对海岸带的依赖。都市圈的战略规划应当遵循社会经济发展的自然规律。都市圈的形成是较长时期的历史积淀结果。它们早在农业经济时代就是人口密集、水网发达地区的河港,近代工业经济发展时期,又成为面向大洋的海港,在信息时代,必须再向现代化的航空港和信息港的方向发展。多港融合,才能具备世界级自由港的功能。这是区域经济发展的终极目标。从地缘经济来看,大都市圈一般具备明显的地域经济优势,具有明显的金融中心龙头效应,占有GDP的绝对比重。随着城市通勤圈的不断扩张和大陆腹地的袭夺,大都市圈通过不断的城市扩张,打破了行政区划的时空分布模式,推动了区域经济重组,并促使其向跨国经济发展。都市圈的发展极不平衡,各具特点,总体上表现出发展的阶段性和空间分异的规律性。就目前比较成熟的三大都市圈,从地缘关系上看,京津冀都市圈具有人文优势,珠三角背靠国际大都市香港,具有亚洲优势,而长三角更具“蝴蝶效应”潜质,展现出吸引全球的世界魅力。都市圈内部各城市之间也存在着激烈的中心城市竞争。因城市化的天时(经济发展水平、发展机遇)、地利(区位优势)与人和(人为因素影响程度)的基础不同,都市圈凝聚力和竞争力的提高,需要在科学发展观指引下,因势利导,统筹规划,因地制宜,优势互补,去跨越各自发展中的门槛。都市圈普遍存在大都市的通病,而且应急反应能力十分脆弱。在都市圈规划和发展过程中,必须针对目前存在的各种生态环境问题,从都市圈整体可持续发展的角度,统筹规划,有针对性地研究制定解决方案和应急预案,防患未然。  相似文献

Evolution and spatial patterns of spheres of urban influence in China   总被引：2，自引：1，他引：1  
This article presents the findings of a study of the spheres of urban influence with regard to all cities in China（not including Hong Kong,Macau and Taiwan Province of China）in the years 1990,2000 and 2009.An optimized gravity model with comprehensive time distance was used to carry out a detailed analysis of the spatial patterns of Chinese spheres of urban influence and the spatial characteristics of urban agglomerations.Such urban agglomerations are characterized by high density population and a developed economy,which are also considered as the national competition unit.This paper initially identifies four spatial patterns of urban agglomerations based on the spatial layout of city groups during their evolution.Some basic characteristics of urban agglomerations are outlined,including the number of cities,the size of cities and the functions of urban centers.These characteristics are examined by using statistical methods and Geographic Information System（GIS）.The main findings from this research are that the development stages and structures of urban agglomerations in China vary significantly.It is also clear that the stages and evolution of spatial patterns are strongly affected and dominated by both policy and location factors.  相似文献

Aircraft industry is very important to the economy and security of a country, and aircraft industry clusters have already existed in the world. Based on Input-Output data and Czamanski’s method, the aircraft industry clusters in China and USA were identified quantitatively in this paper. Furthermore, this article carried out comparison analyses of the identification results. The research finds out: 1) a mature aircraft industry cluster would be generally composed of 7 industrial subgroups, including aircraft industry, metal making and products manufacturing industry, machinery and equipment industry, electronics industry, automobile industry, material industry and others, and electronics industrial subgroup will play a more and more important role in the cluster; 2) in the range of industry-covering, the level of industry-linkage, and the economic performance, there is a tremendously large gap between the aircraft industry cluster of China and that of USA; 3) the spatial evolution of these clusters or centers is highly consistent with the diffusion of a country’s industrialization. Finally, based on those findings, the paper gives some advice on how to improve Czamanski’s method and what China should do to develop its own competitive aircraft industry: 1) China should employ institutional innovation, and turn to be market-oriented; 2) China should abandon the traditional pattern of closed-development, and strengthen the interaction and collaboration between aircraft industry and related industries, especially the electronics industry; 3) China should rectify and perfect its spatial development planning of aircraft industry.  相似文献
