Abstract: Nowadays, China has paid much attention to industrial energy consumption. In fact, household energy consumption, close related to everyones daily life, is playing a more and more important role. In this paper, we utilize input-output model to obtain the value of indirect household energy consumption. We find out the structures of direct and indirect consumption and the gap between rural and urban energy consumption. The results show that the energy consumption structure is cleaner than before, and the gap between rural and urban energy consumption is narrowing. We make the suggestions that clean coal technology is badly needed and supplying more natural gas is helpful.

Abstract: This article focuses on the circular economy development mode of JSIC. Through the steps of making efficient use of resources, highly efficient conversion of energy, vigorously developing the application of energy saving technology, integrated innovation, turning waste into resources and distributed management, the company minimizes the pollution emissions of production and consumption, makes waste harmless, and obtains high economic and environmental benefit at the lower cost. The case indicates that improvement of production mode will help steel and iron company maintain the sustainable development.

Abstract: In this paper, from the perspective of network innovative process, we comes up with the basic assumption, that is, the network innovation can promote absorptive capacity of industrial clusters products so as to improve the innovation performance of the enterprises in cluster. On the basis of this, this paper adopts correlation analysis method to verify the influence extent of productive service industry cluster innovation network on innovation performance. Therefore, we find critical influencing factors of network nodes and set up the innovation performance evaluation index system of productive service industry cluster.

Abstract: Emission tax is one of the most efficient economic mechanisms to reduce carbon emissions. Under the situation that government imposes tax , we develop a two-stage dynamic game model. First, Government achieves total carbon emissions targets by imposing carbon tax. Second, two companies constitute a Cournot duopoly market. Companies adjust their output and the proportion of carbon emissions to maximize profits. And through numerical analysis, we find that: When the Government set up the target emission, it will encourage companies to invest carbon emissions abatement, and enable companies to reduce carbon emissions. And then the Government may reduce the rate of carbon tax. Finally, Government and companies can get win-win situation. In the Cournot duopoly market , Abatement Company has more advantage in the competition of the market and more sustainable under the constraint of carbon tax. Otherwise, Non-abatement company is more sensetive to the changes of carbon tax.

Abstract: This paper calculates the carbon emissions in the three northeastern provinces from 1997 to 2011 by using carbon formula, and compares the differences of the carbon emissions among the three provinces. Based on the LMDI model, the paper reveals the influences of every factor on the industrial carbon emissions. The population, economic development and industrialization rate are the pull factors in the increasing industrial carbon emissions, and the economic development is the main reason, followed by industrialization rate, the population has the least impact. The energy efficiency and structure of energy consumption are the inhibitory factors in the increasing industrial carbon emissions, energy efficiency is the most important factor to reduce industrial carbon emissions, and structure of energy consumption has a small impact on the industrial carbon emissions.

Abstract: As a comprehensive industry, Tourisms development can faster the overall ascension of a city. The multiplier effects caused by tourism attract more and more researchers attention. . Jinan is an open city which is famous for its springs. At present, the evaluation about the chain effects of Jinan tourism effect is still vacant. Taking Jinan as an example, from three aspects including economy, society and ecology by empirical analysis, the cascading positive influence that the spring tourism brought to Jinan is discussed. And it conformed that spring tourism development is of far-reaching significance for Jinan from different angles, such as accelerating tertiary industry development, the industrial structure optimization, increasing the foreign exchange income, industrial branding, urbanization develop with a faster speed, a profound impact on spiritual value, local traditional folk revival, the awakening of consciousness of ecological civilization , increasing green area and reforming urban environment and reducing the environmental pollution.

Abstract: We use the tax survey data of the central treasury, combine with the trajectory and evolution path of China's private economy, introduce a non-parameter DEA method to calculate the Malmquist index and analyze the quality of tax sources and the level of total factor productivity of private enterprises in the post financial crisis era. We find out that the total factor productivities of the three industries have increased in the recent years, nut of different extents. Specifically speaking, there are more efficiency improvement and technical progress in tertiary industry than that in secondary industry, while there is an obvious trend that the secondary industry is shifting to the tertiary industry. At the same time, the status of the first industry has been consolidated and improved.

Abstract: Entropy method and Data Envelopment Analysis (DEA) method are adopted to carry out an effective analysis on the circular economy development of Liaoning Province between 1992 to 2011, and the results show that: the decentralization strength of input-output efficiency of Liaoning Province in this period was great, the gross efficiency of circular economy development was shocking while improving and the development trend varied in different stages; the scale efficiency was higher, and the influence of scale efficiency was higher than technical efficiency, so it can still obtain higher gross efficiency through expanding production scale. Legislation, technological innovation, green consumption and policy support are key measures for promoting the circular economy development.

Abstract: This paper first analyzed the background of the construction of low carbon city and pointed out the advantages and disadvantages of the low carbon construction of Qingdao. Finally, this paper proposed some practical countermeasures and suggestions for the development of low carbon economy in Qingdao.

Abstract: Cities are the main contributors of anthropogenic greenhouse gases (GHGs) emissions. Comprehensive countermeasures are needed in cities to mitigate GHGs emissions. The aim of this paper is to study the results that Shanghai achieved in carbon mitigation by comprehensive green measures. It demonstrated that Shanghai has made significant progress in carbon emission reduction through technological innovation, industrial structure adjustment, and energy efficiency improvement in recent years. The results showed that Shanghais energy related CO₂ intensity reduced to 1.14 t/10⁴ yuan in 2010, owing to adjustments in energy structure and industry structure. It also showed that Shanghai had made abundant reduction in carbon emissions in the past few years. 9.2 million tons of CO₂ reductions were obtained in industry, transportation, and building in the city level. Among them, reductions in industrial sector and transportation were the major contributors. Further efforts should be taken to realize a low carbon future.
