China and the United States are both major countries in the world in the production of and trade in wind energy products, and they are also important trading partners. Therefore, it is of great practical significance to analyze and evaluate the Sino-US bilateral wind power complementarity for re-examining their respective comparative advantages and re-understanding the benefits that trade liberalization brings to both countries, in an attempt to strengthen the trade relations between China and the United States and enhance trade complementarities in wind energy products under the global circumstances of fierce competition. In this paper, based on the trade data from the UN Comtrade database in 2007-2016, a quantitative analysis was conducted on the complementarity of Sino-US wind energy products, by adopting the quantitative research methods of trade combination degree index (TCD), export similarity index (SI) and trade complementarity index (TCI). The results shows that: i) the total trade volume of wind energy products between China and the United States has increased rapidly, and the trade surplus between China and the United States has been expanding year by year; ii) the overall trade balance of wind energy products trade between the two countries is generally stable, and the dependence of China's wind energy products on the United States is much higher than that of the U.S wind energy products on China; iii) the Sino-US wind energy products between China and the United States are highly competitive in the international market; iv) Sino-US wind energy products have different degrees of complementarity in bilateral trade. Finally, this paper proposed policy implications based on the findings of this study. [ABSTRACT FROM AUTHOR]

With the sustainable development background and in order to meet the economic transformation, energy structure adjustment and environment demand, energy services industry has attracted more and more attention and got rapid development, but the current theoretical system of energy services industry is still not perfect now. The economic contribution degree analysis of each factor input in the energy service industry can help the industry to break growth bottleneck, promote development, and achieve more social and environmental benefits. By constructing the economic growth model for various elements in the industry, the paper analyzes the contribution rate of input factors and the influence of industrial economic growth on the society economy. The results showed that the factor of enterprise growth ability has the highest contribution rate to the energy service industry's economic growth, followed by the capital input and labor input, and the contribution rate of human capital, knowledge capital and policy factors is relatively small. The result has practical significance to China's energy service industry development at the present stage, at the same time, the research framework and method put in the paper can give certain reference for the study of other industrial.

In the course of China's rapid economic development, huge amount of energy has been consumed. Therefore, the development of green buildings is of vital significance in reducing industrial energy consumption. This paper conducted an empirical study on the influencing factors of the green performance of civil buildings by adopting the generalized additive model. The results show that: (1) Government mandatory policies play a dominant role in green building development in China; (2) The role of local subsidies will be smaller and the best effect occurs when the subsidy is 2.2 USD/m² or higher than 5.9 USD/m²; (3) Air quality in different regions has an impact on green building performance; (4) When the construction scale exceeds 20,000 m², the greater the construction scale, the lower the building green performance. Finally, this paper proposed countermeasures to further improve the green building performances in China. [ABSTRACT FROM AUTHOR]

As a clean and renewable energy source, hydropower benefits the sustainable economic growth. But in the process of hydropower development, it causes migration and environment problems among hydropower developers, immigrants and ecological environment. To solve the interest conflict of all three parties, this paper first applies the replication dynamics analysis methods of evolutionary game theory to study the relationship among parties involved; secondly establishes a tripartite payment matrix and analytical dynamic equations to solve stability strategies of three parties in different conditions; finally, based on the stabilization strategy of game results, it proposes three suggestions for the sustainable hydropower development.

China is a large country of cement production and consumption, which produces a large amount of environmental pollution and energy consumption in the production process, which runs counter to the economic development goal of low energy consumption and heavy environmental protection in our country. Cement production generates more than 35% of the thermal energy lost, and if that part of the energy is recycled, it will effectively change the situation. In this paper, the status and mechanism of waste heat power generation are analyzed. Taking waste heat recovery and utilization in the new dry process cement production as the research object, the design and construction of the automatic control system for waste heat power generation are discussed. The measured results show that the system of automatic control effect is good. [ABSTRACT FROM AUTHOR]

In order to protect the national petroleum security, combining with the actual situation in China, this paper establishes evaluation index system of petroleum security in China under the background of international oil price fluctuation, determines supply, consumption, trade, geopolitics and ecology 5 basic indexes and 15 specific indexes, and applies the DHGF (the combination of Delphi method, analytic hierarchy process, gray clustering analysis method and fuzzy evaluating method) and entropy technology model to evaluate China's petroleum security situation from 1995 to 2016. The result of evaluation shows that petroleum security was in a "relative dangerous" state from 2000 to 2013 and returned to "general" from 2014 to 2016. It is a new trial on evaluation method of petroleum security to evaluate China's petroleum security situation by using the DHGF and entropy technology model, which provides a new research idea and method for petroleum security evaluation.
