The results showed that urban consumption growth made the most contribution to aggregate consumption growth, followed by urban-rural migration caused consumption. The role of rural consumption growth kept stable, but consumption caused by population growth was decreasing. Therefore, China consumption growth mainly relies on urban consumption expenditure and urban-rural migration.展开更多

Using household surveys collected in Guangzhou, China, in 2001, 2005 and 2010, excess commuting measurements are estimated. Excess commuting shows an overall trend of increasing during 1990–1999, and then declining during 2000–2010. We argue that deepening marketization of the jobs and housing sectors has induced spatial separation of jobs and housing. In other words, institutional transition and urban spatial restructuring are underpinning the changes of commuting patterns in Chinese cities. Excess commuting has strong relationship with individual socio-demographic status, which is by and large due to the increasing flexibilities of jobs and housing location choices enjoyed by urban residents. The findings call for considerations on balancing jobs-housing in making public policies relevant to urban development in general, and land use and transportation in particular.展开更多

A calculation approach of urban flesh water consumption was presented based on the theory of urban basic material consumption and the input-output method, which was utilized to calculate urban fresh water consumption of China, and to analyze its structural change and causes. The results show that the total urban flesh water consumption increased 561.7× 10^9m^3, and the proportion to the total national flesh water resources increased by 20 percentage points from 1952 to 2005. The proportion of direct and induced water consumption had been continuously rising, and it increased by 15 and 35 percentage points separately from 1952 to 2005, while the proportion of indirect water consumption decreased by 50 percentage points. Urban indi- rect water consumption was mainly related to urban grain, beef and mutton consumption, and urban induced water consumption had a close relationship with the amount of carbon emission per capita. Finally, some countermeasures were put forward to realize sustainable utilization of urban fresh water resources in China.展开更多

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

The study used primary and secondary data. Both descriptive and inferential statistical techniques were used to analyze research questions that bother on urban liveability. Results of the analyses show that in the two urban centres the following are not in very good condition： neighborhood road quality, garbage collection, state of cleanliness, street light, state of security, pollution, water supply, drainage system, and power supply. Most of the residents are not satisfied with the state of liveability in Ago-Iwoye and Ijebu-Igbo towns. Statistical test result shows among others that there is no significant variation in the level of urban dwellers＇ satisfaction with their neighbourhood condition. In order to improve urban liveability in the two urban centres, government should provide all necessary infrastructural facilities and services. While roads are to be improved and maintained, electricity and water supply should be provided. Community associations should also be encouraged. They should be more involved in activities that will improve liveability in the urban centre. They should constitute themselves as pressure groups, working on the government to improve the liveability of the urban centre.展开更多

As incomes increase and the urbanization process accelerates, the consumption of pork by Chinese residents will continue to grow. This paper studies the proportion of the household pork consumption account and examines the use of apparent pork consumption as a bridge that links consumption and production. Based on the pork consumption of urban and rural residents from 2000 to 2012, combined with per capita income, the total population and the rate of urbanization, we can analyse China＇s market demand in the pork trade for 2020, which will be useful for countries who are interested in potential trade with China. The research shows two important findings： First, with the per capita income of urban residents increasing, their per capita pork consumption is also on the rise, and as increasing numbers of rural residents move to urban areas with the acceleration of urbanization in China, the urban areas will be the most important pork market in the future. Secondly, the per capita pork consumption of rural residents will still be lower than that of urban residents in 2020, so there will be more room for growth in pork consumption in rural areas.展开更多
