Explaining the evolution of cooperation remains one of the greatest problems for both biology and social science. The classical theories of cooperation suggest that cooperation equilibrium or evolutionary stable strategy between partners can be maintained through genetic similarity or reciprocity relatedness. These classical theories are based on an assumption that partners interact symmetrically with equal payoffs in a game of cooperation interaction. However, the payoff between partners is usually not equal and therefore they often interact asymmetrically in real cooperative systems. With the Hawk–Dove model, we find that the probability of cooperation between cooperative partners will depend closely on the payoff ratio. The higher the payoff ratio between recipients and cooperative actors, the greater will be the probability of cooperation interaction between involved partners. The greatest probability of conflict between cooperative partners will occur when the payoff between partners is equal. The results show that this asymmetric relationship is one of the key dynamics of the evolution of cooperation, and that pure cooperation strategy (i.e., Nash equilibrium) does not exist in asymmetrical cooperation systems, which well explains the direct conflict observed in almost all of the well documented cooperation systems. The model developed here shows that the cost-to-benefit ratio of cooperation is also negatively correlated with the probability of cooperation interaction. A smaller cost-to-benefit ratio of cooperation might be created by the limited dispersal ability or exit cost of the partners involved, and it will make the punishment of the non-cooperative individuals by the recipient more credible, and therefore make it more possible to maintain stable cooperation interaction.

This paper presents a definition of L-fuzzifying nets and the related L-fuzzifying generalized convergence spaces. The Moore-Smith convergence is established in L-fuzzifying topology. It is shown that the category of L-fuzzifying generalized convergence spaces is a cartesianclosed topological category which embeds the category of L-fuzzifying topological spaces as a reflective subcategory.

Yunnan university of finance and Trade recording to t he statistics of chain’s output of tea, Yunnan province has entered the ranks of the larger ones of the production in China. Yunnan’s tea industry has the natur al resources and the economic effects envied, on the orther hand, Yunnan’s tea m arket has gradually become less and the economic effects have been poor. Through our comprehensive investigation and study, we consider that because the supply chain has seriously been disjointed among production, supply and sale of tea ind ustry in Yunnan, the supply chain of Yunnan’s tea industry need to be reorganize d for the promoting the development of Yunnan’s tea industry. The essence of reengineering of Yunnan’s tea industrial supply chain is to set u p the model of the trailed operation,to strengthen the strategic partnership man agement between the supply chain, to optimize the design of the supply chain and build up and improve the working mechanism for management of the tea industrial supply chain. The structure of Yunnan’s model of tea industrial supply chain: the model of com mercial flow; the model of logistics flow; the model of information flow and the model of cash flow. The solutions and policies for the reorganization of Yunnan’s tea industrial sup ply chain: planning, logistics and distribution and sales. Set up the supporting system of information technology. Build up the control system of production and *** the working mechanism of Yunnan’s tea industrial supply chain. Implement the engineering of exporting Yunnan’s tea into the markets of other p rovinces and foreign markets. Have many the channels that raise the funds of dev elopment for Yunnan’s tea industry.

为了比较不同所有制银行成本效率差异,本文建立共同前沿成本函数(Metafrontier Cost Function),计算技术缺口比率(Technology Gap Ratio,TGR)指标,以避免传统效率评估模型只能考虑相同技术水平情况的缺陷,以此指标作为银行群组间技术水平与成本节省幅度的比较标准,同时讨论中国商业银行业规模经济与范围经济现象。实证结果显示,现阶段股份制商业银行总体更具成本效率。1985～1993.期间,两类银行在规模经济,1993.之后则呈现显著规模不经济。而在两个期间内,两类银行均存在着显著的范围经济,此结果表明'混业经营'是中国商业银行业未来发展的必然趋势。

在引入特定的宏观经济、金融和政策变量等控制变量后,本文尝试检验东欧、东亚和拉丁美洲三大主要新兴经济体的资金流动方向及其对经济增长的影响。实证结果显示:东欧地区收入水平与金融深化程度仍然偏低,但随着发展程度提高,未来将由资金流入转为流出。东亚地区的超额外汇储备、贸易顺差与资金流出,被指控为造成美国巨额经常账户赤字与全球经常账户失衡的主要原因之一。但该地区若能够持续进行金融深化,资金可能回流并使全球经常账户失衡现象得以缓解。至于拉丁美洲地区的宏观经济、金融和政策变量,对资金流动方向并无决定性影响,财政与货币政策仍是决定资金流入能否有助于经济增长的关键因素。最后,本文对解决我国国际收支不平衡问题提出了政策建议。

Linear mixed models are popularly used to fit continuous longitudinal data, and the random effects are commonly assumed to have normal distribution. However, this assumption needs to be tested so that further analysis can be proceeded well. In this paper, we consider the Baringhaus-Henze-Epps-Pulley （BHEP） tests, which are based on an empirical characteristic function. Differing from their case, we consider the normality checking for the random effects which are unobservable and the test should be based on their predictors. The test is consistent against global alternatives, and is sensitive to the local alternatives converging to the null at a certain rate arbitrarily close to 1/V~ where n is sample size. ^-hlrthermore, to overcome the problem that the limiting null distribution of the test is not tractable, we suggest a new method： use a conditional Monte Carlo test （CMCT） to approximate the null distribution, and then to simulate p-values. The test is compared with existing methods, the power is examined, and several examples are applied to illustrate the usefulness of our test in the analysis of longitudinal data.
