Abstract: By constructing the environmental and economic development model, this paper analyzed the coordinated degree on environment and the economy in 31 provinces of China. The results showed that, the differences on economy and environment are great in various regions. From the economic development level, we could see that the eastern regions were the best, the central were the better and the west were the worst. From the environment development level, we could see that the western region is the best, the east is better, and the middle is the worst. From the coordinated degree of environment and economy, the eastern region obviously were higher than that in the midwest, and the economy and environment in eastern regions formed the benign coordinated development, but the midwest fails to form a positive development situation.

Abstract: In this paper, the wind power fluctuation is divided into three categories. For the purpose of balancing all kinds of wind power fluctuation to enhance the penetration levels of wind power, we propose an active-parallel hybrid energy storage system (APHESS). The APHESS is composed of a battery, a supercapacitor, and two charge-discharge controllers. By combining the battery with the supercapacitor, the APHESS obtains the enhanced energy storage performance. Therefore, the investment cost can be reduced. By the reasonable design on the operation mode of APHESS, the APHESS can interchange power precisely with the wind power system. Furthermore, the battery and supercapacitor can suppress separately different kinds of wind power fluctuation to make their own energy storage properties fully utilized. The APHESS can be widely used in wind farm for the real-time regulation on wind power

Abstract: Using geothermal resources to instead of steam bled form the turbine steam to preheat feed water in a conventional Rankine cycle power station is also termed as geothermal aided power generation (GAPG), this offers a significant potential for the large-scale utilization of geothermal energy for power generation. GAPG enables the conversion of low temperature geothermal energy in the case of 90-260°C into power at a higher efficiency. In GAPG system, geothermal heat is used to preheat the feed water of power generation, instead of the extraction steam, thus the steam flows through the lower stages turbine have changed. In other words, the lower stage turbine works under off-design conditions. However, previous simulation models for the GAPG and solar aided power generation (SAPG), have not considered this turbine off-design operation. Under the off-design conditions, the isentropic efficiency of the turbine and pressure, temperature of each stage of turbines change which lead to the change of the output of turbine. In this paper, a modified thermodynamic model has been developed, considering these changes, which then can estimate the performance of a GAPG plant more accurately than the previous models. The results from various models are compared in this paper.

Abstract: As there are physical differences exist in the different factors of production, and have different relationship with the economic growth, so they have different impact on economic growth. The various factors of production play the inequality role in producing, leading to the inequality social relationship between owners of various factors of production. In this context, this article systematic combing the theoretical that endowments of the factors of production in domestic and foreign literature and the empirical research literature, it provides overview for domestic control segmentation of the social production units, and also for the development of theory which social patterns deductive and the practice patterns study to carried out.

Abstract: As one of the border tax adjustments, Carbon tariffs, especially their legality under the framework of WTO rules, have been the focus of arguments in recent years. This article analyzes the legality of carbon tariffs under the framework of WTO rules and puts forward to countermeasures to deal with carbon tariffs in China by studying the legal regulations on border tax adjustment in WTO rules.

Abstract: With the fast development of rural tourism, there have been increasing damages and destructions to the ecological environment and tourism resources of country-based scenic spots. As a result, the dilemma between economic development and environment protection restricts the sustainable development of rural tourism. In view of this, this paper analyzes the relationship between environment protection and the sustainable rural tourism development and summarizes how the former will positively influence the latter.

Abstract: Energy efficiency is one important index of a regional economic and social sustainable development strategy. To find some original factors influenced on the energy efficiency, we used energy data concerned during 1996-2008 in China and calculated the efficiency data in Laspeyres Decomposition, then analyzed the factors' influence values and energy efficiency's developing trend, at last, put forward the strategic advice. The data showed that energy intensity has declined from 1996 to 2008, and energy intensity change was mainly affected by technological progress factors. Except for 2002 to 2003, the energy intensity was declining in rest periods, and the factor of technological progress and the factor of the drop in life consumption have been playing positive roles to the decrease in the energy intensity, while the unreasonable industrial structure change had a negative effect on the decrease in the energy intensity.

Abstract: Changchun is an old northeastern industrial city, after the liberation of our country's industrial development has made an outstanding contribution at a time when China's First Automobile Factory of is a typical representative. It is the new socialist China witnessed great achievements of history, but also the cradle of new China auto industry. The author of the China First Automobile Factory of Industrial Heritage status to conduct a detailed survey, protection and use of several models in order to address the urban development in the effective protection of industrial heritage and use issues.

Abstract: Technology progress is essential to keeping energy supply uninterruptable and maintaining sustainable economic growth. In this paper, we develop an endogenous growth model with energy research and make analysis of the relationship between energy research and economic growth by means of dynamic optimization. We find that the long run economic growth rate is related to the intensity of energy research work and a greater intensity of energy research activity will result in a higher increasing rate of energy supply sources. We also find energy research has special effects on labor force redistribution. Investment in the energy research sector will break free from decreasing marginal return of energy production and will eventually help economy step into sustainable growth.
