Energy Price Policy Decision-Making Model under Energy Conservation Environment

When the price of one commodity changes, its social demand will also change. As a motivation for the social economic development, once energy consumption price changes, producers will change the product price which will affect the final consumers and cause the social demand changes. The change of every social products price and demand will directly affect the gross social production value .And every products different price elasticity will change the economy structure and energy consumption situation which will further affect the emission pollution. So grasping the implementing effects of energy price policy helps to formulate a proper energy price policy, optimize the economic structure, improve the energy efficiency and lower the pollution emission level without seriously influencing the economic development. This paper focuses on the differential power pricing policy and sets up its influencing and decision-making models to the energy price policy.

Risk Analysis of Regional Energy Efficiency in China Based on DEA

Energy is the foundation of modern social economy, and energy efficiency is an important issue that various countries concerned. By using the Data Envelope Analysis (DEA) method, we studied Chinas regional energy consumption and treatment situation of waste water and air pollution. So we can draw the conclusion that energy efficiency is generally good in the South China, the Northeast and the Northwest, which energy efficiency risk is low. But the efficiency is low in the North China and the East China. At the same time, the returns to scale of energy are decreasing in the North China, the East China, the Central China and the Southwest, so they should reduce the consumption of energy and enhance the treatment of waste water and air pollution, in order to reduce the Chinas regional energy efficiency risk.

Allocation Model of Total Energy Consumption and Pollutant Emission Control Based on Low-Carbon Economy and its Significance

As the rapid development of Chinese economy, the total energy consumption and pollutant emission increased increasingly, which lead to a terrible situation in energy safety and environmental pollution. In the meantime, the greenhouse gas (GHG) and pollutants (such as SO2, NOx and NH3-N) generated by energy consumption increased, and the above pollutions had brought a substantial negative impact on global climate change and low-carbon economy (LCE) development. This paper analyzed the situation of energy consumption in China, and revealed the significance of total energy consumption. Energy consumption control based on LCE theory was the effective protection measure of national resources and energy security, and could promote the economic development and adjustment of industrial structure, which was investigated from three aspects expressed as three allocation models in the article. The results indicated that, energy consumption control can promote development of LCE by protecting eco-environment and sustaining security of energy and resources, and supporting steady development of our society by minimizing the utilization of energy, and the above aspects would be the key points in control of total energy consumption and pollutant emission during the 12th Five-Year Planning in China.

This paper demonstrates the energy conservation reconstruction and comprehensive utilization of the existing buildings in the industrial urban renewal in various aspects in order to promote the sustainable development objectives of the industrial urban renewal.

DEA analysis of FDI attractiveness for sustainable development: Evidence from Chinese provinces

The paper extends the Malmquist productivity index to establish a theoretical model to evaluate foreign direct investment (FDI) attractiveness. This model and its implementation mechanism consider cost efficiency and profit efficiency changes that represent the influence of price level on inputs and outputs respectively. Using data from China from 1997 to 2008, we assess the attractiveness of FDI in terms of human capital stock, material capital stock, energy consumption situation, and degrees of market openness. We use data envelopment analysis to find the bottleneck of FDI attractiveness and to identify the potential market of each province. This study contributes to the literature by providing sound investment advices to multinational corporations. It also offers policy advice and guidelines to developing nations for setting policies and programs to attract FDI. Specifically, our results provide useful inputs for policy makers to create a mechanism design to attract FDI in the host country.

Research on the energy performance and indoor environment quality of typical public buildings in the tropical areas of China

Hainan province is the only tropical and island province in China, with the unique climatic and geographical features. It has a different energy performance in public buildings from those in the inland areas. This paper investigated the current situation of energy consumption of the sampled public buildings, including 26 hotels, 24 office buildings and 7 department stores, through analyzing utility billing data, on-site survey and measurement, and site operational records. The breakdowns of energy consumption found out that the electricity dominated the energy consumption for all the sampled buildings and the air conditioning system played a key role in the energy consumption of major building services. By analyzing the main factors for building energy consumption, the annual average energy use indexes were calculated to be 141.63kWh/m2, 87.70kWh/m2, and 166.95kWh/m2 for hotels, office buildings and department stores, respectively. Besides, the comparison between Hainan province and other areas revealed that the building energy consumption of this tropical province was at a low level. Because indoor environment quality can influence the health and work efficiency of humans in buildings, field tests on the indoor environment quality were also carried out, and the performance of indoor environment quality was rated.
