In the pre-reform era, the city was defined as a productive space under the system of urban-rural segregation established for securing rapid industrialization. Urban planning was thus only concerned with the development of urban areas. In the 1980 s and 1990 s after the reform, institutional change and economic transformation mobilized the urban-rural linkages. The development of suburban areas was then considered by urban planning, but this consideration was a passive response to urban problems such as population explosion and water resources protection. Since the new millennium, the agenda for sustainable development and problems of uneven urban-rural development have called for the development of urban-rural integration. In this context, the city is conceptualized as a complex of mountain, city, river, farmland and sea, reconstructing the ideology of urban-rural division in defining urban development. Urban planning has therefore sought in an active way to develop a sustainable city embracing rural and natural elements, and to balance economic growth and environmental protection. It is argued that developing the concept of city as a complex of urban and rural elements contributes to the urban planning for sustainable urban development, while this conceptualization relies on the recognition of the integrated urban-rural relationship.展开更多

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 spa-tial 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, migra-tion, 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 car-rying out spatial management and development planning of metropolis fringe area.展开更多

The researchers can be divided into two schools according to their emphasis. One emphasizes particularly the urban development, and the other pays attention to the urban-rural income gap. However, there is a very strong association between urbanization rate and urban-rural inequality. As far as it goes, there is a paradox between urbanization and urban-rural inequality in China. This main reason lies' in the different temporal and spatial scales chosen by the scholars. Making use of correlative analysis and wavelet method, this paper rethinks and sums up the commonly evolving characteristics and trends between urbanization and urban-rural gap from 1950s to now. There is an intensively positive correlation between urbanization and urban- rural consumption gap. In general, with the acceleration of urbanization, urban-rural gap of China has undergone three stages of cyclical fluctuations. The rapid urbanization results in the increase of urban-rural highly risky. In addition, the special stage of urbanization is the other reason that expands urban-rural gap.展开更多

However, most of these studies started mainly from the standpoint of the city govemment, drumming for the land- scape-oriented urbanization, namely pulling-down the urban village and constructing the splendid residence or business buildings. The article maintains that the most important thing the city government should do is to pay much attention to the sustainable living of urban villagers, who would lose their main income source, namely, the collective dividend and the family housing rent. The single method of compensation has been proved to be harmful to the villagers' community, in which some young villagers relying on rent were no longer to do anything but stay at home. On the other hand, considering the floating population has become the main stream of renters in urban villages, the emergence of urban villages was inevitable and would continue to exist in a long time under the socio-economic transition in urban China and globalization. Based on the analysis above, the transformation of urban village should take more concerns on the housing demands of floating population besides compensation for local villagers. Meanwhile, it is necessary to avoid the “landscape-oriented urbanization” without the “peasant-to-citizen” transformation.展开更多

Results: There is a cause-and-effect relationship, as well as duality, between the urban-rural income gap and the level of population urbanization in Jiangxi Province. With continuous promotion of the urbanization course in 1990-2014, the income gap between urban and rural residents in Jiangxi Province presents a phenomenon of expanding first, narrowing second and expanding again.展开更多

It takes the industry and agriculture, city and countryside as a whole, with overall planning and coordination development, through system innovation and policy adjustment, in order to realize the integration development of urban and rural planning construction, industrial development, infrastructure, ecological environment and social career. This paper conducts the empirical analysis on the urban and rural integration construction development of Changji City of Changji Region in Xinjiang, studying the existing problems and restrictive factors of the process in promoting urban and rural integration construction in western region of China and trying to propose the corresponding countermeasures.展开更多

The paper will firstly illustrate the purposes and principles of integrating urban and turn/medical insurance systems. Then, with the development of socialist core value--equity, the consideration of the development of the social security system, and the consideration of the strengthening of the rural and urban economy, integrating three main basic health insurance systems is required to take place urgently, In the last part, it provides the strategic development of the inter,ration of the dual svstem.so as to build an uniform social insurance system.展开更多

Using the technology choice index (TCI) to measure the degree to which government policy is biased towards capital-intensive sectors, this paper conducts empirical tests of a series of theoretical hypotheses on the basis of Chinese provincial panel data for 1978-2008. We further find that changes in China's urban-rural income gap conform to a U-curve pattern, i.e. in the course of economic development, the income gap first decreases then increases.展开更多

In 2013, in order to mitigate increasingly severe urban water-related problems, China set forth a new strategy for integrated urban water management(IUWM) called the "Sponge City". This is the first holistic IUWM strategy implemented in a developing country that is still undergoing rapid urbanization, and holds promise for application in other developing countries. This paper aims to comprehensively summarize the sponge city. First, this paper reviews prior studies and policies on urban water management in China as important background for the sponge city proposal. Then, the connotations, goals, and features of the sponge city are summarized and discussed.Finally, the challenges, research needs, and development directions pertinent to the sponge city are discussed based on investigations and studies conducted by the authors. The sponge city in China has a short history—given this, there are many issues that should be examined with regard to the stepwise implementation of the Sponge City Programme(SCP). Accordingly, the authors perceive this study as only the beginning of abundant studies on the sponge city.展开更多

The "economic absorption and social exclusion" of semiurbanization path has attracted rural residents to cities. These people participate in the urban economy just as a factor of production (labor) without enjoying the rights that urban citizens(xfiUagers) have. This urbanization path and population mobility has had a profound influence on rural democracy in China. On the one hand, large numbers of young people have left; the traditional villages in central and western China, which are characterized by population output( many even move with their entire families), causing the villages to lose their political elite while the interaction chain between villagers has been shortened and social trust in the villages has been weakened, thereby giving rise to a low quality of rural democracy. On the other hand, large numbers of migrant workers have flocked into the urbanized villages in eastern China, which are characterized by population input, and these people far outnumber local residents. Migrant workers are excluded from rural democracy and the governance structure. This local citizenship based on the household registration system restricts the inclusiveness of village democracy.展开更多
