Countries in the world have taken a variety of means to control carbon emissions based on the serious situation of global warming,the concept of low-carbon economy and the provisions about emissions in the United Nations Framework Convention on Climate Change(UNFCCC) and the Kyoto Protocol.With the measures of emissions reductions,the system of carbon emissions trading is taking shape.It is necessary for China as the big natural resources consumption country to establish its own carbon emissions trading system.By introducing the carbon emissions trading system of the European Union,America and Japan,and analyzing the market and policies been formed,the carbon emissions trading system in China can be established from the initial configuration of the emissions rights,the subject and object of carbon emissions trading,establishing the carbon emissions trading exchange and supervising and regulating the carbon emissions trading.  相似文献

During the rapid urbanization period, the contradiction between demand for the construction land and the preservation of cultivated land for food security is getting more and more serious in China. With the urbanization the rural settlement land is increasing instead of decreasing; This paper aims at.finding the driving forces for rural settlement land expanston. Based on land use change survey data (1996-2006) by the Ministry of Land and Resources P. R. C., this paper find, that per capita area for rural settlement land is more than per capita area for city; township and industrial land in each province except Tibet. Besides, rural settlement land area and per capita rural settlement land area are increasing while the rural poputation is decreasing in most provinces. The main problems of rural settlement land use are low efficiency, high vacancy rate, chaotic layout and illegal occupancy. Then the driving forces [br rural settlement land expansion, including economic development, family income, family scale, psychological factors, urbanization, transportation, lack of planning, limited circulation of dwelling-house land and imperfect sociat security, ate explored based on above analysis, Finalty, policy recommendations, in view of different influencing factors, are put forward to control the disorder expansion of rural setttement land.  相似文献

In this work we develop aggregate car ownership and bus fleet models in order to forecast and compare fuel consumption and CO2 emissions from passenger cars and buses. Greece was selected as a case study, being a country fairly representative of lower-income Mediterranean and Eastern European countries and data were collected for the period 1970 to 2002. Percent adults in the population, per capita gross domestic product, inflation, unemployment, car occupancy and bus kilometers were predictors included in the car ownership and bus fleet multiple regression models. A shift in the overall trend of both models around 1995 was explained as a slope change of per capita gross domestic product, possibly reflecting the impact of a boom of the Greek Stock Market along with a retirement program for older vehicles. Predictor variables were forecast via Box-Jenkins and the models were subsequently used to develop car ownership and bus fleet forecasts to the year 2010. We predict that the contribution of cars to total CO2 emissions will rise to an astounding 95% of total CO2 emissions from road passenger transport (excluding taxis and mopeds), an effect expected in other Mediterranean and Eastern European countries with socioeconomic characteristics similar to Greece. Suggestions for further research include developing regional car ownership forecasts in order to compare the dynamics of different regions within a country and looking into other land transportation means (such as mopeds, taxicabs and railway).  相似文献

This paper investigates the long run Granger causality relationship between economic growth, carbon dioxide emissions and energy consumption in Turkey, controlling for gross fixed capital formation and labor. The most interesting result is that carbon emissions seem to Granger cause energy consumption, but the reverse is not true. The lack of a long run causal link between income and emissions may be implying that to reduce carbon emissions, Turkey does not have to forgo economic growth.  相似文献

20世纪80年代以来,中国发生了规模空前的人口流动,人口流动统计必被提到议事日程上来。中国特有的户籍制度引起人们对人口流动概念理解的歧义,从而出现社会上和学术界对相关概念和指标使用的混乱。笔者根据中国的国情,从统计学的角度对与流动人口有关的问题进行了探讨,提出了新的人口流动概念,并在此基础上,设计了一套科学适用的流动人口统计指标体系,以期解决当前存在且亟待解决的问题。  相似文献

探讨了改革开放以来中国的市镇设置标准和市、镇人口统计口径的变化与中国城市化发展之间的关系。市镇设置标准和市、镇人口统计口径等行政因素对中国城市化水平有重要影响。当前,中国的城市化水平具有高估的现象,表现在城镇人口中农业人口的比重过高和城镇就业人口中从事第一产业的人口比重较高。未来中国城市化的发展在提高城市化水平的同时,更重要的是需要提高城镇人口中非农业人口的比重,改善城镇人口的就业结构,同时制定客观、合理的市镇设置标准和市、镇人口统计口径,使中国的城市化水平真正反映中国城市化的实际发展状况。  相似文献

Most of the existing literature dealing with the relationship between carbon emissions, energy consumption and economic growth either suffers from ignoring relevant variables such as trade openness or investment, or suffers from using econometric methods that are unable to distinguish between short- and long-term causality and are not robust to the degree of integration of time series used for the analysis. This article suggests using the autoregressive distributed lag approach along with additional explanatory variables such as measures of trade and investment to shed a new light on the link between emissions, energy consumption and income in the two largest and energy-intensive developing economies: China and India. Our results, over the 1971–2009 period, provide evidence that investment plays a major role in shaping the relationship between carbon emissions, energy consumption and income in China while this is not the case in India. Furthermore, trade openness is found to play a key function in the short term in China but does not contribute to the emissions-energy-growth scenario in India.  相似文献

ABSTRACT

This paper examines the empirical relationship between the presence of inclusive institutions and the pattern of economic growth in a cross-country setting. We find evidence that the presence of inclusive institutions, indicated by political democracy, positively affects consumption share. In turn, the increase of the latter in the preceding year is associated with a significantly higher rate of total factor productivity (TFP) growth. The link from democracy to TFP growth via consumption is stronger for countries of higher levels of income. These findings suggest that institutional inclusiveness may have become increasingly important for economic growth when the level of income rises. We also provide preliminary evidence that consumption may have facilitated productivity growth via the channels of increasing innovations and reducing social conflicts. The findings shed lights on the structural transformations toward a more inclusive and sustainable model of growth in China today.

A key feature of Flexible Fourier Form (FFF) is that the essential characteristics of multiple structural changes can be captured using a small number of low frequency components from a Fourier approximation. We introduce a variant of the FFF into the trend function of US real GDP in order to allow for gradual effects of unknown numbers of structural changes occurring at unknown dates. We find that the hypothesis of no changes can be rejected, and the Fourier components are significant. Our new cycle matches the NBER chronology very well, especially for the Great Recession of 2009.  相似文献

中国碳排放强度与影响因素的关联分析   总被引:1,自引:0,他引:1  
碳排放强度与影响因素的关联程度,直接影响正确判断和把握碳排放强度的发展方向。通过分析碳排放强度及其影响因素的灰色关联度大小,来制定控制碳排放强度的短期和长期政策。文章基于美国橡树岭国家实验室二氧化碳信息分享中心(Carbon Dioxide Information Analysis Center,CDIAC)提供的我国2000-2011年全国碳排放量数据,核算出中国各年度的碳排放强度,通过采用灰色系统理论中灰色关联分析方法,分别从静态、动态的视角研究中国碳排放强度与技术进步、人口、经济增长、产业结构、能源价格以及城镇化率的关联关系,取得的研究结果表明,技术进步是影响我国碳排放强度的主要因素,其次是产业结构和人口;技术进步对碳排放强度的绝对关联关系和相对关联关系都是最大;能源价格影响碳排放强度的相对关联度较高,但是能源价格的绝对影响因素较低。因此中国应该在发展低碳经济建设的同时,综合考量各个影响因素,积极调整相关政策,科学实现我国碳减排目标。  相似文献
