On the basis of fully explaining peasant workers’ transformation to urban residents, a method for measuring its process has been advanced and then confirmed with the data of March in 2005 from surveys to peasant workers in Wuhan. Finally, the suggestions of acceler-ating peasant workers’ transformation to urban residents to pro-mote the construction of a harmonious society have been drawn from the analysis.展开更多

All of those national policies in city areas are much better than those in rural areas, so those corresponding differences bring about great discrepancy of the economic status (mainly including GDP per person and income per resident) between rural and city areas in the same urban region, especially in different urban re- gions because the percentage of urban residents in those urban regions is in-equable. The present paper mainly researches the topic of relationship between the percentage of urban residents and the economic status in an urban region in China, including the relationship between the economic and the political functions of a settlement in China during the process of urbanization.展开更多

Their least preferred occupations are mainly those in which migrant workers are relatively concentrated, such as the construction industry and the hospitality industry. The category of social distance between the two groups is mostly medium or remote. There is a certain level of asymmetry in their evaluations of social distance. Social distance is greatly influenced by differences in social status, cultural differences, spatial segregation, and informal institutions. Social distance between urban residents and migrant workers has been diminishing continuously, and a degree of social integration between them has occurred.展开更多

The main conclusions are as follows. Firstly, economic development in different sectors is unbalanced and especially consumption insufficiency is emerging; secondly, the effects of households by income group on the commodities are different; thirdly, consumption capability of Chinese urban residents is in the stage of durable consumable, but the highest income group is swifting to the higher stage and households with low income are entering the stage; finally, Chinese clothing, service and information industries have huge potential to develop while the latent demands are scarcity for that of the food, resident and education, cultural and entertainment industries.展开更多

Improving the equity of basic health services is one of the tasks of the new healthcare reform in China. This study aimed to analyze the parallel and vertical equity of health service utilization of urban residents and then find its influencing factors. Methods In August 2011, a household survey was conducted at 18 communities of Baoji City by multi-stage stratified random sampling. Based on the survey data, we calculated a concentration index of health service utilization for different income residents and a difference index of different ages. We then investigated the influencing factors of health service utilization by employing the Logistic regression model and log-linear regression model. Results The two-week morbidity rate of sampled residents was 19.43%, the morbidity rate of chronic diseases was 21.68%, and the required hospitalization rate after medical diagnosis was 11.36%. Among out-patient service utilization, the two-week out-patient rate, number of two-week out-patients, and out-patient expense had good parallel and vertical equity, while out-patient compensation expense had poor parallel and vertical equity. The inpatient service utilization, hospitalization rate, number of inpatients, days stayed in the hospital, and inpatient expense had good parallel equity, while inpatient compensation expense had poor parallel equity. While the hospitalization rate and number of inpatients had vertical equity, the days stayed in hospital, inpatient expense, and inpatient compensation expense had vertical inequity. Conclusions Urban residents＇ health was at a low level and there was not good health service utilization. There existed rather poor equity of out-patient compensation expense. The equity of inpatient service utilization was quite poor. Income difference and the type of medical insurance had great effects on the equity of health service utilization.展开更多

Based on 513 questionnaires, it uses descriptive statistical analysis and binary logistic model to analyze the consumption and influencing factors of woolen products. The results indicated that residents in the middle region were more inclined to purchase woolen sweater compared to the residents in the east region. Urban residents were more inclined to purchase woolen sweater compared to the rural residents. Personal income,satisfaction degree of quality, and style have significant positive impact on whether residents purchase woolen sweater, and purchasing quantity of cotton sweater has significant negative impact on whether residents purchase woolen sweater.展开更多

Empirical data were collected via in-depth interviews with low-income urban residents and were analyzed using qualitative methods. This paper discusses the research findings based on the more noticeable results of information seeking behavior among these people. Our approach touches on a focused study of such issues as what the role of information seeking in their everyday life is, what information they care about, which information channels they prefer to use, which factors influence their information seeking behavior, how difficult it is to seek the information they need, and how they use public libraries. Based on our research findings, we propose that public libraries should provide customized information services for urban low-income residents according to the unique characteristics of their information seeking behavior in everyday life.展开更多

文摘Clean-energy substitution technology for existing residential buildings in cities is an inevitable choice for sustainable development and low-carbon ecological city construction.In this paper,the current status of energy-saving renovation and renewable-energy applications for existing residential buildings in various cities in China was summarized by using statistical methods.The geographical distribution of clean-energy power generation in primary energy production in China was explored in depth.According to different climatic divisions for existing urban residences,clean-energy production and consumption were analyzed and predicted based on the STIRPAT model.The results show that the energy consumption of urban residential buildings in 2016 increased by 43.6%compared with 2009,and the percentage of clean energy also increased from 7.9%to 13.4%.Different climatic regions have different advantages regarding clean energy:nuclear power generation leads in the region that experiences hot summers and warm winters,whereas wind and solar power generation lead in the cold and severely cold regions.The present results provide basic data support for the planning and implementation of clean-energy upgrading and transformation systems in existing urban residences in China.
