These problems have brought about new characteristics and changes to the consumption structure of rural residents. This paper divided the urbanization into population urbanization,industrial urbanization and land urbanization. Using the panel data of 31 provinces in 2004-2013,it established the dynamic panel model and analyzed the effects of different types of urbanization on the consumption structure of rural residents. Results indicated that population urbanization exerts a negative effect on development-oriented consumption expenditure of rural residents,while it exerts a positive effect on enjoyment consumption expenditure; the industrial urbanization exerts a negative effect on the consumption expenditure of rural residents,while it exerts a positive effect on clothing and transportation communication consumption of rural residents; land urbanization exerts a negative effect on medical care expenditure in enjoyment consumption of rural residents. In view of these problems,it came up with recommendations,including stimulating the development of rural consumer market,liberating the consumption potentiality of rural areas,making clear emphasis points of different types of urbanization,avoiding promoting the urbanization in a blind manner,and adjusting the development of different types of urbanization on the basis of the consumption demands of rural residents.展开更多

Expanding rural residents' consumption becomes a necessity for enlarging domestic demand, solving three agriculture problems and promoting sustainable and rapid economic development. The research shows that since invigorating old industrial base in Liaoning, the contribution rate of rural residents' consumption to economic motivation is low and unstable, which has become one of the choke points for the development of economy. By using the grey correlation method, the influences of rural residents' consumption in different periods to GDP per capita are analyzed, the results show that the consumption level of rural residents were increasing, but their contribution rate on economic growth showed the descending tend. The residential expenses stay in the major position of consumption expenses; the education and entertainment products and service consumption play an important role; the growth of transportation and telecommunication is slow; the expenses on medical care are low and its contribution rate on economic growth is relatively weak. The countermeasures on developing rural economy, increasing rural residents' income, improving rural consumption environment, accelerating rural infrastructure construction, constructing and perfecting rural social security system and expanding rural consumption credit market are put forward to expand rural residents' consumption demand and realize the sustainable development of economy.展开更多

Result shows that urban residents in Guangxi has relatively low propensity to consume. And their consumption, especially the middle and low-income families, is mostly concentrated in food, cloth, lodging and other basic necessities of life, which account for more than a half of their income. Based on this, corresponding suggestions are put forward to enlarge the consumption demand of urban residents in Guangxi, such as increasing the regulation of income redistribution, minimizing the gap between the rich and the poor, enhancing the overall consumption level, cultivating the consumption hot spots for the urban residents, and actively guiding the enjoyable consumption.展开更多

The results showed that overall the income gap between China's rural areas was on the rise from 1998 to 2006,and the income gap was mainly caused by the gap between the East China,Central China and West China. After 2006,it showed a slow decline. The dynamic panel data model established for consumer demand,spending habits,income,regional income disparities showed that income and regional income disparities significantly influence consumer demand of rural residents. Before 2006 regional income gap inhibited the consumption of rural residents,but it promoted consumption after 2006.展开更多

This paper expanded Logarithmic Mean Decomposition Index method through introducing variables of urbanization and residential consumption into the model. It also analyzed the influences of six factors as energy structure, energy intensity, population scale, urbanization, residential consumption, and consumption inhibit on regional household energy consumption. Results showed that in 2003-2012, impact of urbanization on regional household energy consumption of Chinese three areas was significantly higher than population size. The "population gathered in eastern region" phenomenon caused eastern region getting the largest population scale effect. Driving force of residential consumption on regional household energy consumption was much higher than the other five effects. Due to the comparative advantage of residential consumption compared with government consumption, investment, and net export, the decrease of consumption ratio promoted the growth of regional household energy consumption. Energy intensity in Chinese three regions kept reducing in 2003-2012. The progress of energy utilization technology slowed the growth of regional household energy consumption, and energy intensity effect was most significant in the central region.展开更多

This paper divided the urbanization into population urbanization,industrial urbanization and land urbanization. Using the panel data of 31 provinces in 2004-2013,it established the dynamic panel model and analyzed the effects of different types of urbanization on the consumption structure of rural residents. Results indicated that population urbanization exerts a negative effect on development-oriented consumption expenditure of rural residents,while it exerts a positive effect on enjoyment consumption expenditure; the industrial urbanization exerts a negative effect on the consumption expenditure of rural residents,while it exerts a positive effect on clothing and transportation communication consumption of rural residents; land urbanization exerts a negative effect on medical care expenditure in enjoyment consumption of rural residents. In view of these problems,it came up with recommendations,including stimulating the development of rural consumer market,liberating the consumption potentiality of rural areas,making clear emphasis points of different types of urbanization,avoiding promoting the urbanization in a blind manner,and adjusting the development of different types of urbanization on the basis of the consumption demands of rural residents.

文摘Liaoning is a granary province with a large agricultural population and great market potential. Expanding rural residents' consumption becomes a necessity for enlarging domestic demand, solving three agriculture problems and promoting sustainable and rapid economic development. The research shows that since invigorating old industrial base in Liaoning, the contribution rate of rural residents' consumption to economic motivation is low and unstable, which has become one of the choke points for the development of economy. By using the grey correlation method, the influences of rural residents' consumption in different periods to GDP per capita are analyzed, the results show that the consumption level of rural residents were increasing, but their contribution rate on economic growth showed the descending tend. The residential expenses stay in the major position of consumption expenses; the education and entertainment products and service consumption play an important role; the growth of transportation and telecommunication is slow; the expenses on medical care are low and its contribution rate on economic growth is relatively weak. The countermeasures on developing rural economy, increasing rural residents' income, improving rural consumption environment, accelerating rural infrastructure construction, constructing and perfecting rural social security system and expanding rural consumption credit market are put forward to expand rural residents' consumption demand and realize the sustainable development of economy.

文摘Taking the rural residents in Yanqing District of Beijing as the research object,through field investigations and interviews,it is found that the main characteristics,income and expenditure level,preference and cognitive level of rural residents are the factors that affect the dairy consumption behavior of rural residents.Using the bivariate regression model for empirical analysis,it is concluded that rural residents'occupation,monthly average income,purchase expenditure and attitude towards dairy safety have a significant impact on rural residents'dairy consumption behavior,and then relevant constructive suggestions are put forward to guide rural residents'balanced consumption.
文摘Although currently,a large part of the existing buildings is considered inefficient in terms of energy,the ability to save energy consumption up to 80%has been proven in residential and commercial buildings.Also,carbon dioxide is one of the most important greenhouse gases contributing to climate change and is responsible for 60%of global warming.The facade of the building,as the main intermediary between the interior and exterior spaces,plays a significant role in adjusting the weather conditions and providing thermal comfort to the residents.In this research,715 different scenarios were defined with the combination of various types of construction materials,and the effect of each of these scenarios on the process of energy loss from the surface of the external walls of the building during the operation period was determined.In the end,these scenarios were compared during a one-year operation period,and the amount of energy consumption in each of these scenarios was calculated.Also,bymeasuring the amount of carbon emissions in buildings during the operation period and before that,let’s look at practical methods to reduce the effects of the construction industry on the environment.By comparing the research findings,it can be seen that the ranking of each scenario in terms of total energy consumption is not necessarily the same as the ranking of energy consumption for gas consumption or electricity consumption for the same scenario.That is,choosing the optimal scenario depends on the type of energy consumed in the building.Finally,we determined the scenarios with the lowest and highest amounts of embodied and operational carbon.In the end,we obtained the latent carbon compensation period for each scenario.This article can help designers and construction engineers optimize the energy consumption of buildings by deciding on the right materials.
文摘According to the household consumption data of urban residents in Guangxi Statistical Yearbook in the year 2009, the ELES (Extended Linear Expenditure System) is used to analyze the consumption structure, the propensity to consume, and the consumer flexibility of urban residents in Guangxi Zhuang Autonomous Region of China in the year 2008. Result shows that urban residents in Guangxi has relatively low propensity to consume. And their consumption, especially the middle and low-income families, is mostly concentrated in food, cloth, lodging and other basic necessities of life, which account for more than a half of their income. Based on this, corresponding suggestions are put forward to enlarge the consumption demand of urban residents in Guangxi, such as increasing the regulation of income redistribution, minimizing the gap between the rich and the poor, enhancing the overall consumption level, cultivating the consumption hot spots for the urban residents, and actively guiding the enjoyable consumption.

文摘This paper measures the Chinese regional income distribution gap based on the Theil index with data of 31 provinces in China from 1998 to 2011. The results showed that overall the income gap between China's rural areas was on the rise from 1998 to 2006,and the income gap was mainly caused by the gap between the East China,Central China and West China. After 2006,it showed a slow decline. The dynamic panel data model established for consumer demand,spending habits,income,regional income disparities showed that income and regional income disparities significantly influence consumer demand of rural residents. Before 2006 regional income gap inhibited the consumption of rural residents,but it promoted consumption after 2006.
文摘By selecting the relevant indices of data concerning the income and consumption of urban residents and rural residents in Chongqing City from 2000 to 2009,we adopt empirical analysis method and comparative analysis method to conduct comparative analysis from overall level,consumption structure and regional difference.The results show that income level is the most direct and fundamental factor impacting urban-rural residents'consumption,and eventually determines the consumption level and consumption structure of urban-rural residents;the consumption structure of urban-rural residents in Chongqing City takes on prominent dual structure,with conspicuous gap between urban areas and rural areas;the level of income and consumption of urban-rural residents in Chongqing City is lower than the national average,especially for the rural residents;the gap of income per capita and consumption per capita of rural residents in"One-hour Economic Circle"and"Two Wings"of Chongqing City is prominent.Corresponding policy suggestions are put forward as follows:improve financial transfer payment system;quicken the pace of urbanization;coordinate urban-rural industrial development;guide farmers to establish correct consumption idea.

文摘Demographic urbanization caused great changes in scale of residents' consumption and residents' lifestyle and then impacted changes of regional household energy consumption. This paper expanded Logarithmic Mean Decomposition Index method through introducing variables of urbanization and residential consumption into the model. It also analyzed the influences of six factors as energy structure, energy intensity, population scale, urbanization, residential consumption, and consumption inhibit on regional household energy consumption. Results showed that in 2003-2012, impact of urbanization on regional household energy consumption of Chinese three areas was significantly higher than population size. The "population gathered in eastern region" phenomenon caused eastern region getting the largest population scale effect. Driving force of residential consumption on regional household energy consumption was much higher than the other five effects. Due to the comparative advantage of residential consumption compared with government consumption, investment, and net export, the decrease of consumption ratio promoted the growth of regional household energy consumption. Energy intensity in Chinese three regions kept reducing in 2003-2012. The progress of energy utilization technology slowed the growth of regional household energy consumption, and energy intensity effect was most significant in the central region.
