中国城市区域经济发展格局与改进策略分析

文章指出影响城市区域经济发展格局的主要因素有自然条件、产业基础和人文社会条件。在这三大因素作用下,全国形成了由东中西与南中北相交而成的"九州方圆"式的城市区域经济格局。在此基础上,指出了各城市区域经济发展存在问题和改进策略。

Urban Hierarchy of Innovation Capability and Inter-city Linkages of Knowledge in Post-reform China

The 2000s has witnessed increasing interests in cities′role of innovation in the era of knowledge-based economy.Compared with substantial empirical analysis on the world city hierarchy of innovation,this paper attempts to examine the national urban hierarchy of innovation capability in China,in terms of ranking systems,spatial pattern and inter-city linkages of knowledge during the post-reform period since the late 1970s.Based on quantitative analysis such as principal component factor analysis and clustering analysis,this paper identifies the five-tier hierarchy of in-novation,which is headed by Beijing and Shanghai,followed by the capital cities of each province and regional centre cities.The development of China′s urban hierarchy of innovation capability has been driven by such factors as the scale of innovation,scientific scale,innovation potential and innovation environment.The paper further investigates the inter-city linkages of knowledge measured by the number of co-authored papers among the cities.Beijing is positioned in the central position of the knowledge diffusion and knowledge cooperation innovation.More knowledge diffusion among high level cities has occurred than that among the low level cities as well as between the low level cities and high level cities,and provincial capital cities and the regional central cities.

Revisiting and Rethinking Regional Urbanization in Changjiang River Delta,China

China is entering a critical and accelerating phase of urbanization.As one of the most urbanized regions in China,the Changjiang(Yangtze)River Delta has experienced dramatic urbanization and urban transformation.However,in the recent years,many changes have taken place in this region and there is limited attention to the regional urbanization path evolution,its problems and the way to solve these problems.Therefore,we should revisit the urbanization process in the Changjiang River Delta again.In this paper,we revisited urbanization paths of the Changjiang River Delta by data analysis,influence factors of urbanization by the Gray Relational Analysis,and major challenges to urbanization of the Changjiang River Delta by theoretical considerations.We found that the urbanization of the Changjiang River Delta had experienced several stages of large-scale spatial and urban system restructuring.Within the Changjiang River Delta,Shanghai,Zhejiang and Jiangshu had experienced different urbanization path with local characteristics.But with their development model gradually converging,their urbanization model is also converging.We also found that the major influence factors affecting the Changjiang River Delta urbanization were dynamic change and urbanization was driven by different key factors in different socio-economic development stages.Meanwhile,the Changjiang River Delta urbanization is facing many problems such as existing institutional arrangements,including the hukou(household registration)system and others which can not meet the needs of current socioeconomic development and urbanization.Therefore,it is imperative to promote institutional innovation and adopt a new urbanization development strategy for the sake of the orderly and sustainable urbanization development in the Changjiang River Delta.

Regional Disparities of China's Economic Development during 1992-2013——Based on DMSP/OLS Nighttime Lights Data of Cities

Balanced regional development is essential to China's economic stability and efficiency and achievement of the goal to build a moderately prosperous society in all respects. Based on the DMSP/OLS nighttime lights data of 291 cities at or above prefecture level during 1992-2013, this paper examines the regional disparities and trends of Chinese mainland's economic development. The findings are as follows:(1) During sample observation period, China's overall regional disparities generally declined despite some volatility; China's intra-regional disparities have been curbed yet a consistent framework for inter-regional economic coordination is lacking.(2) Southern coastal region contributes a significant share to China's overall regional disparities as the developed cities of Guangdong Province did not create a significant spatial spillover effect on neighboring regions.(3) According to the result of spatial Markov transition probability estimation, spatial factor has played a remarkable role in the evolution of China's regional economy and proximity to high-level regions will accelerate a region's transition toward higher levels.

Regional differences of border geo-cities in China and the surrounding countries

As the improvement of international status and the implementation of China's neighboring diplomacy, the development of border regions and the security of border cities, as well as their spatial structure and regional differences are gaining more attention from academic circle. Based on the interdisciplinary perspectives of urban geography, regional economics and geopolitics, this paper explores the regional differences of border geo-cities in China and the surrounding countries with the help of remote sensing information acquisition and Arc GIS spatial analysis. Three primary results are found as follows:(1) The border geo-cities in China and surrounding countries are divided into five geographical regions: geo-cities in South China Sea, geo-cities in Southeast Asia, geo-cities in South Asia, geo-cities in Central Asia and geo-cities in Northeast Asia.(2) In the spatial structure system of China's border geo-cities, the importance of geo-cities in five major regions is fairly different. In terms of the security and economic development, the rank of priority is geo-cities in Northeast Asia, geo-cities in South China Sea, geo-cities in Central Asia, geo-cities in South Asia, geo-cities in Southeast Asia.(3) Considering China's geo-setting for the development of border geo-cities, the east region is significantly better than the west, and the north region is slightly better than the south.
