From the perspective of farmers' income increase,this article evaluates the optimal scale of rural fixed-asset investment by setting up model with statistic data,and the results show that the optimal scale of per capita rural fixed-asset investment is 76. 35% of per capita net income of rural residents,which has been reached in China in 2009. Therefore,compared with the adding of rural fixed-asset investment,a better income increase effect can be achieved through the adjustment of rural fixed-asset investment structure.展开更多

So there is no fuel price risk, and it, of course, does not include the environmental costs, such as carbon emissions. Because of these unique advantages, wind power has gradually become an important part of the strategy of sustainable development in China. Now with the growing voices on global greenhouse gas emission reduction, and as a clean and efficient energy, wind power has huge potential in combating climate change, energy security pressures and the needs for energy. Wind power in China began to develop from the 1980s. In the first 20 years, the speed of development was slow; but since 2004, it has had an extremely rapid growth.This paper, in order to study the development mechanism of China's wind power industry, investigated and analyzed the status quo of wind power industry in China, and then found that (1) the development trend of wind power industry in China appears exponential growth; (2) China's installed capacity of wind power is still smaller than that os some other countries; (3) new subsidy policies bring developing opportunities to wind power industry in China; (4) the sectors of wind power industry are in unbalanced growing; (5) the owners of proposed wind farms are too optimistic though the built wind farm had many problems. In addition, by using the methodology of Game Theory, this paper has also constructed the matrix of pre-assessing risks of China's wind power industry to further discuss the potential risk factors within China's wind power industry as risk factors of wind farm construction, risk factors of production of wind turbines, risk factors of parts and components manufacturing industry under risk indicators like R&D, patents, the domestic policy, the international policy, the quality of products and the market regulation, in order to provide a scientific assessment and self-assessment tool for investors or implementers, and also to promote the further development of the wind power industry.展开更多

It discusses how we can dynamically choose candidate assets, achieve the possible maximum revenue and reduce the risk to the minimum level. The paper generalizes Markowitz’s portfolio selection theory and Sharpe’s rule for investment decision. An analytical solution is presented to show how an institu- tional or individual investor can combine Markowitz’s portfolio selection theory, generalized Sharpe’s rule and Value-at-Risk (VaR) to find candidate assets and optimal level of position sizes for investment (dis-investment). The result shows that the gen- eralized Markowitz’s portfolio selection theory and generalized Sharpe’s rule improve decision making for investment.展开更多

Taking 515 farmers in 27 villages of Hubei Province as investigation objects,the influence of farmer social capital on cooperative supply willingness of agricultural disaster reduction public goods is explored by Logistic regression model. Research results show that social solidarity,common value concept,social trust and reciprocal content have positive impact on farmer's willingness of cooperative supply,while annual household income,number of agricultural disaster reduction public goods and social network have negative impact on farmer's willingness of cooperative supply.展开更多
