随着农民工进城务工数量的增加,农村家庭生活能源消费也发生了变化,为探究其中的机制,本文基于陕西省农村地区"劳动力转移与农村生活能源"的调查数据,应用多元线性回归模型与Tobit回归模型分析农民工进城务工对农村家庭生活能源消费量的影响。研究发现:农民工进城务工收入显著提升了农村家庭液化气消费量和电力消费量,同时显著降低了生物质能源的消费量;农村家庭基本特征、农村家庭经济特征、农户消费偏好及区域等因素对农村家庭生活能源消费量也具有重要影响。农民工进城务工显著优化了我国农村生活能源消费结构,提高其生活水平,对解决我国目前"人民日益增长的美好生活需要和不平衡不充分的发展之间的矛盾"具有重大意义。  相似文献

<正>能源结构指能源总生产量或总消费量中各类一次、二次能源的构成及其比例关系。能源结构是能源系统工程研究的重要内容,它直接影响国民经济各部门最终用能方式,并反映人民生活水平。能源结构分为生产结构和消费结构。各类能源产量在能源总生产量中的比例,称为能源生产结构;各类能源消费量在能源总消费量中的比例,称为能源消费结构。研究能源结构,可以掌握能源的生产和消费状况,为能源供需平衡奠定基础。查明能源生产资源、品种和数量,以及消费品  相似文献

八十年代后期,世界资源研究所与《全球能源终端利用方案》课题组合作,对发展中国家能源消费状况作了深入调查研究,在此基础上,发表了《全球能源终端利用方案》的研究报告.报告中提出:在有效利用终端耗能设备先进技术与加强科学管理同时,只要适度增加能源工业建设,发展中国家就能够在避免破坏环境条件下,获得促进工农业生产较快发展和满足人们较好生活所需的能源供应.如果仍保持目前的能源消费水准发展下去,经过20~30年,其人均能源消费量虽也能达到工业国家目前的水平,但人们的综合生活质量甚至不如今日.其核心问题是能源未能得到有效且合理利用,能源的利用效率还是很低下的.国外专家们提出了能源终端需求战略的新思想,已受到一些发展中国家的高度重视,认为这是解决发展中国家能源问题的希望所在.  相似文献

中国居民生活与CO_2排放关系研究   总被引:2,自引:0,他引:2  
本文采用Consumer Lifestyle Approach(CLA)方法,比较分析中国各地区和不同收入水平下居民的二氧化碳排放量。结果表明,城镇居民直接二氧化碳排放一直处于增长状态,农村增速较缓慢。城镇居民间接二氧化碳排放量高于直接消费。城镇居民食品、衣着、居住、教育文化是主要的二氧化碳排放源,农村居民食品消费占据主要比例。地区间的差异对于居民间接二氧化碳排放影响主要体现在总量上,收入水平对居民生活方式的间接二氧化碳排放量影响大,高收入水平的居民二氧化碳排放量高于低收入水平居民;收入水平越高,二氧化碳排放结构越多样化。根据研究提出了降低生活能源强度和二氧化碳排放强度的建议。  相似文献

中国农村生活用能及其碳排放分析(2001-2010)   总被引:1,自引:0,他引:1  
分析了2001~2008年中国农村生活用能的变化以及2001~2010年中国农村生活用能对气候变化的影响。研究发现,农村生活用能呈现了从非商品能源向商品能源转变的趋势,其中,传统生物质能源的消费比例从81.5%下降至70.9%,而商品能源则从17.1%上升至25.1%。此外,除传统生物质能源外的其它可再生能源的消费增长迅速,年均增长率为19.8%。与此相应,农村生活用能消费所导致的碳排放呈现出显著的增加趋势,由152.2百万t上升至366.89百万t,且农村人均CO2排放的增长速度是同期城镇人口的1.87倍。分析认为,影响商品能源消费的主要因素是农村居民收入的增加,强有力的政策支持则促进了农村除传统生物质能源外其他可再生能源的发展。  相似文献

The process of urbanization and the raise of living standards in China have led an increasing trend in the patterns of residential consumption. Projections for the population growth rate in urban areas do not paint a very optimistic picture for energy conservation policies. In addition, the concentration of economic activities around coastal areas calls for new prospects to be formulated for energy policy. In this context, the objective of this paper is twofold. First, we analyse the effect of the urbanization process of the Chinese economy in terms of the long-run patterns of residential energy consumption at national level. By using the concept of club convergence, we examine whether electricity and coal consumption in rural and urban areas converge to the same long-run equilibrium or whether in fact they diverge. Second, the impact of the regional concentration of the economic activity on energy consumption patterns is also assessed by source of energy across Chinese regions from 1995 to 2011. Our results suggest that the process of urbanization has led to coal being replaced by electricity in urban residential energy consumption. In rural areas, the evidence is mixed. The club convergence analysis confirms that rural and urban residential energy consumption converge to different steady-states. At the regional level, we also confirm the effect of the regional concentration of economic activity on residential energy consumption. The existence of these regional clusters converging to different equilibrium levels is indicative of the need of regional-tailored set of energy policies in China.  相似文献

我国的能源消费城乡差距大,能源消费结构极不合理,农村地区是能源贫困的重灾区。文章在文献综述的基础上,对农村地区目前使用的电力、煤炭、薪柴、汽油/柴油、煤油、液化气、沼气、太阳能等九种能源结构分析发现,受访地区农村家庭能源贫困主要体现为家庭能源消费支出贫困和家庭能源消费结构贫困。从解决途径来看,发展农村地区绿色电力、提高农村家庭经济收入、优化农村家庭能源消费结构、实施农村家庭能源贫困救助是值得提倡和可行的。  相似文献

There exist many differences between urban and rural China among which residential CO2 emissions arising from energy consumption is a major one. In this paper, we estimate and compare the energy related CO2 emissions from urban and rural residential energy consumption from 1991 to 2004. The logarithmic mean Divisia index decomposition analysis is then applied to investigate the factors that may affect the changes of the CO2 emissions. It is found that energy intensity and the income effects, respectively, contributed most to the decline and the increase of residential CO2 emissions for both urban and rural China. In urban China, the population effect was found to contribute to the increase of residential CO2 emissions with a rising tendency. However, in rural China, the population effect for residential CO2 emissions kept decreasing since 1998.  相似文献

In the context of rapid urbanization and new construction in rural China, residential building energy consumption has the potential to increase with the expected increase in demand. A process-based hybrid life-cycle assessment model is used to quantify the life-cycle energy use for both urban and rural residential buildings in China and determine the energy use characteristics of each life cycle phase. An input–output model for the pre-use phases is based on 2007 Chinese economic benchmark data. A process-based life-cycle assessment model for estimating the operation and demolition phases uses historical energy-intensity data. Results show that operation energy in both urban and rural residential buildings is dominant and varies from 75% to 86% of life cycle energy respectively. Gaps in living standards as well as differences in building structure and materials result in a life-cycle energy intensity of urban residential buildings that is 20% higher than that of rural residential buildings. The life-cycle energy of urban residential buildings is most sensitive to the reduction of operational energy intensity excluding heating energy which depends on both the occupants' energy-saving behavior as well as the performance of the building itself.  相似文献

This study proposes the development of thermal and energy consumption maps to generate useful planning information. A residential neighbourhood in a medium-sized city was selected as the study area. In this area, 40 points were taken as urban reference points where air temperatures at the pedestrian level were collected. At the same time, rural temperatures made available by the city meteorological station were registered. Data of electrical energy consumption of the building units (houses and apartments) were collected through a household survey that was also designed to identify the users’ income levels. Then, maps were developed so that the configuration of urban heat islands and electrical energy consumption could be visualised, compared and analysed. The results showed that the income level was the most important variable influencing electrical energy consumption. However, a strong relationship of the consumption with the thermal environment was also observed.  相似文献

Energy use in developing countries is heterogeneous across households. Present day global energy models are mostly too aggregate to account for this heterogeneity. Here, a bottom-up model for residential energy use that starts from key dynamic concepts on energy use in developing countries is presented and applied to India. Energy use and fuel choice is determined for five end-use functions (cooking, water heating, space heating, lighting and appliances) and for five different income quintiles in rural and urban areas. The paper specifically explores the consequences of different assumptions for income distribution and rural electrification on residential sector energy use and CO2 emissions, finding that results are clearly sensitive to variations in these parameters. As a result of population and economic growth, total Indian residential energy use is expected to increase by around 65–75% in 2050 compared to 2005, but residential carbon emissions may increase by up to 9–10 times the 2005 level. While a more equal income distribution and rural electrification enhance the transition to commercial fuels and reduce poverty, there is a trade-off in terms of higher CO2 emissions via increased electricity use.  相似文献
