Abstract: With our country strengthening the development of intelligent electric grid, reducing net loss as an important means to save energy will undoubtedly play a positive role in promoting low-carbon economy .Actuality of research in power loss calculation and its relative theory at home and abroad is formulated in this work,and the main problem of the methods of power loss calculation exists now is analyzed comprehensively, objectively and systematically. On this foundation, this paper tentatively explored the trend of its research development under the situation of low carbon economy .

Abstract: The comparative advantage of low-carbon and high-carbon materials is determined by one country’ history and natural conditions, which is also the starting point of studying on policy trends for a country to develop low carbon economy. In this paper the method system of international economics is applied, two dimensional coordinate system is set up with environmental friendly materials and high-carbon materials. In this extreme model with only two countries , only to produce and make use of two materials above; we analyzed the cross-border exchange mechanism determined by the relative price level arising from comparative advantage , and then indicated political factors will be an important influence factor in the division of labor between developed and developing countries about carbon reduction.

Abstract: The economic growth in Shanghai is fast and its level of social development has reached that of the moderately developed countries, while shanghai has also been one of the highest CO2 cities. It has adopted many measures to control climate change. The rebound and reduce effect model has been used to analysis the effectiveness of the control of CO2 in the process of low-carbon policy implementation in Shanghai. This model will help policymakers reconsider the implication and limitation of low carbon policy. The results show that currently many policies used in Shanghai are of emergency, and rebound effect is obvious. However, these efficiency-oriented measures are suitable for Shanghai's own development needs.

Abstract: Tremendous FER not only heightened China’s credit level and payment capability, but also is a reflection of unbalanced economic development. Frequent trade frictions are accompanied by European sovereignty debt crisis & serious US government financial deficit, which increased the risk of China’ FER. Domestic environment worsened. Longtime incentive for export & FDI attraction at any cost generated domestic inflation, sacrificed our natural resources and the rights & benefits of the working class, and polluted the natural environment. Based on econometrics software and data from year 1991 to 2011, this paper studies the relationship between environmental protection and China’s FER, regression of which reveals an overly high trade dependence. Both trade surplus and CPI are significantly and positively related with the rapid growth of China’ FER. Nevertheless, FER contributed little to the increase of average township disposable income. Furthermore, the generating mechanism as well as the drawbacks of the rapid growth of China’ FER are analyzed.

Abstract: In recent years, green economy is promoting global economic growth mode transformation with its powerful strength. China is no exception, and agreed to construct a demonstration region of the CHANGSHA-ZHUZHOU-XIANGTAN city-cluster in Hunan province. The region is named Two-oriented society which is resource-saving and environment-friendly. The paper studied High-tech small and medium enterprises (SMEs), which are the main body of the implementation of the Two-oriented society, analyzed of the interaction between the green economy, as well as two types of social construction and SMEs. Through these studies, we concluded those SMEs and government how to achieve environmental and economic interest’s win-win model in the two-oriented society construction process.

Abstract: This paper is involved in the construction of bus operation cycle, through the vehicle test on road to gain the data of bus practical operation mode, using statistical analysis in data processing to construct the operation cycle, and analyze the cycle characteristics. Through the analysis of bus operation characteristics, firstly it was found there were 4 big category modes, namely the idle, constant speed, acceleration and deceleration. Then according to the speed interval of 10 km/h and the acceleration interval of 0.5m/s², each big category mode including of constant speed, acceleration and deceleration can be divided into small interval modes. Finally, bus operation cycle was constructed, which has 4 big category modes,78 small interval modes. The idle time of the operation cycle constructed constitutes 23.03%, the acceleration time and deceleration time constitute 73.64%, the constant speed time constitutes a little. The average speed is 22.7km/h. The characteristics of bus operation cycle above fits the bus operation rule. The operation cycle modes constructed mainly concentrate on the idle and (20-50) km/h, and acceleration and deceleration range from -1.0 m/s²to 1.0m/s².

Abstract: The carbon emission control of Industrial Transfer Park is analyzed from four aspects. Metrics of these four aspects are energy consumption per industrial value added of leading industry, carbon emissions intensity of buildings, carbon emissions intensity of transportation and carbon sinks. On this basis, 36 industrial transfer parks in Guangdong province are analyzed with the method of Hierarchical cluster in order to explore practical measures to reduce carbon emissions in the parks.

Abstract: In recent years, Guangdong has achieved remarkable performance in economic development; meanwhile it is being faced with problems of increasing CO2 emissions. Following the IPCC Guidelines for National Greenhouse Gas Inventories, we estimated the energy-related CO2 emissions in Guangdong during the period of 1980-2010. We employed the logarithmic mean divisia index (LMDI) method to decompose the CO2 emissions into energy intensity, energy structure, per capita GDP and population scale effects. Besides, we deduced the calculation methods for the year by year effects, the accumulated effects and the contribution degrees. Using 1980 as the base year, the empirical results show that the accumulated effects of energy intensity and energy structure in 2010 are negative, while those of per capita GDP and population scale are positive. Per capita GDP is the chief positive influence on the CO2 emissions. Energy intensity is becoming more significant; however, its direction is instability. Population scale has a significant positive effect on the CO2 emissions. Energy structure has a negligible negative impact on the CO2 emissions. Some suggestions on CO2 emissions reduction in Guangdong are given based on the analysis.

Abstract: According to indicators’ information repetition and subjectivity of the indicators’ weight set during the variable fuzzy comprehensive evaluation, Principal Component analysis can help solve the weight of the relative indicators and reduce comprehensive evaluation dimensions of the variable fussy comprehensive evaluation. This paper has made a comprehensive evaluation of the status quo of Yunnan’s low carbon economy development(2005-2009), which turns out to be more practical compared with the mere variable fussy theory analysis, thus, principal component-variable fuzzy evaluation is a kind of feasible way to analyze the regional low carbon development status.

Abstract: Traditional industries have followed the simple but irreversible linear development mode --- "resources obtaining-processing and production --- waste emission", such development mode has brought such problems as resources depletion, energy shortage, ecological destruction, environment pollution, global warming, and species extinction, which has greatly threatened the survival and development of human beings. Thus, it is inevitable to explore a new economic development mode. In this paper, based on investigation and research, though reasonable thinking and systematic analysis, the basic principles for the development of circular economy to be observed have been raised, further, the necessity and feasibility to develop circular economy in west regions have been researched.
