The models of static game and repeated game in which industrial difference is considered are built. The degree of the industrial difference's effects on the level of optimal cooperation and the change of other factor's effect on the level of the optimal cooperation with the change of the industrial difference are analyzed. Some profound results on cooperation are obtained. These results are momentous current significance to explaining some recent economic behavior of Chinese enterprise and leading them to further deepen reform. 相似文献

This paper researches the behavior difference among government,banks and enterprises and how it affects soft budget constraints of enterprises and non-performing loans of banks based with dynamic game.The game model suggests that government will give banks some assistance and let them refinance enterprises,especially government has strong(incentive) to sustain SOEs in China's transitional economy.Banks will do it if the assistance from government is more than the loss from refinance enterprises.In addition the value of liquidation of enterprises and the new loans affect banks' refinancing old enterprises. 相似文献

Based on introducing the concept of Leveraged Buy-outs (LBO) briefly, in this paper, the basic characters of LBO are analyzed. The choice of payoff function and game process in financing game of LBO for both sides by asymmetric information dynamic game model are analyzed as well. Finally, the game equilibrium is gained and the means of some relative policies are discussed. 相似文献

Capital structure of company changes company value in a frictional market environment through cutting down cost and decreasing moral risk and causal problem in trust agency. The authors apply method of asymmetric information game to analyze how to make design of mechanism on the basis of existing revenue and cost of bankruptcy, make the company's manager maximize shareholder's wealth through maximizing own effectiveness, thus define the best radio of liabilities.The authors show that good companies have higher value than difference one in a assured mechanism, afitness capital structure could reduce the problem in trust agency of company's manager,higher risk project can bering more value for compay. 相似文献

In the distribution channel management, a good cooperation relationship between manufacture and wholesaler is an effective way for them to complement each other with their respective advantages, improve channel competitive abilities and adapt to market fluctuations. Based on their mutual cooperative relationship, a mixed game model is constituted by introducing the characteristics and postulating the prerequisites of trade between manufacturer and wholesaler, then the factors affecting their mutual cooperative relationship and the conditions of their stable cooperation are found through analyzing the mixed game model. Furthermore, a finitely repeated game model is used to analyze the cooperation between manufacturer and wholesaler, the conclusion of the cooperative qualification that influences the cooperation of both sides is given. As a result, the strategies employed by the manufacturer and wholesaler are pointed out. 相似文献

This essay illustrates the importance of credit to the supply of asset pool and the operation of MBS from the accept and the basic operation process of MBS. According to our country's conditions, this essay states from two sides. Through the game of housing consumer and commercial, for one thing, housing consumer desides applying for loan or not,and commercial bank desides granting loan or not; for another ,housing consumer selects prepaying loan,paying loan on time or branking contract,and commercial bank selects lawsuiting or not. Through the game analysis of two sides , it discusses relations between the loan of bank and the development of credit system,and give us some suggestions in order to the development of MBS. 相似文献

污泥生物质炭的碳、氮矿化特性及其对大棚番茄产量品质的影响 总被引：1，自引：0，他引：1
为了探讨污泥生物质炭碳、氮矿化规律和肥料效应,采用室内培养和大田设施番茄生产试验,研究了污泥生物质炭的碳、氮矿化特性及其污泥生物质炭对作物产量、品质与肥料利用率的影响。结果表明,在有机碳（或氮）施用量相同条件下,污泥生物质炭的CO2-C矿化量显著低于牛粪生物堆肥(P<0.05),培养21周的污泥生物质炭的碳矿化率仅为牛粪生物堆肥的13.7%。污泥生物质炭处理的土壤氮素平均矿化量显著高于牛粪生物堆肥处理,培养21周污泥生物质炭和牛粪生物堆肥氮素平均矿化率分别为6.9%、1.0%。在较高肥力水平的设施土壤上施用污泥生物质炭或污泥生物质炭,与化肥配施对番茄果实和生物总产量的肥效与等养分量的牛粪生物堆肥和化肥相当,不会降低番茄的营养品质和风味品质,对番茄硝酸盐和亚硝酸盐含量的安全品质影响风险较小。施用污泥生物质炭各处理的氮、磷、钾肥利用率均低于单施牛粪生物堆肥处理,但在不影响作物产量和品质的条件下,对提高设施土壤肥力十分有利。 相似文献

In the seal verification system of bank, the precondition of identifying the seal on notes correctly is the seal Abstracted must be with high quality and low noise. On account of those facts such as the complexity of note background, the shade of inkpad, the randomicity when people seal and the noise cause by sampling, we have more difficulties in stamp Abstracting and mending. After analyzing both the advantages and disadvantages of the RGB and HIS color space model, the authors build a new stamp Abstraction model and propose a new fill algorithm. Experiments indicate that with this Abstraction model they can Abstract the seal with high enough quality and reduce the noise to the least at the same time, and with this fill algorithm they can restore seal better and avoid over-fill at the joint of stroke. So, the requirements of the subsequent seal imprint verification can be met. 相似文献

The authors reveal the certain secretive attribute that quality meta data has,quality meta data secretive to the customer and enterprise's different function and the different expectation,introduce the Dublin core resources set concept,define quality meta data by 6 essential factor constitution method,and distinguish application example that constitute of the standard 6 essential factors.They propose application method and the data flow in view of quality meta data secretive attribute,divide the quality meta data into 3 big types,namely defects meta data,manufacture meta data and function meta data with the premise of the secretive attribute being respected,plan the quality meta data sharing principle and the data transmission flow. 相似文献

After reform of state -owned firms mechanism, many companies appeal for ESO, but there have not been any clear theories for operation in practice until now. On the basis of principal-agent theory of the firm, this paper regards owners and managers as the two sides to game and builds the game model which analyses the behaviors of owners and managers. As a long-term stock based incentive system, ESO will align the goal of owners and managers and make them reach Nash Equilibrium to maximize their utility, and lower agency cost to solve the agency problem in modern firms. 相似文献

基于订单农业风险管理的农民专业合作社创新研究 总被引：2，自引：2，他引：0
为了有效提高农民专业合作社订单农业履约率,促进农业产业化经营。利用博弈论分析订单农业中农户和农业企业违约的条件和原因,指出利用“公司+农民专业合作社+农户”模式和金融衍生工具交易两种方式来解决订单农业违约风险问题。进而分析农民专业合作社在这两种方式中的作用,包括改变农户参与市场的弱势地位,有利于实行农产品标准化生产,提高农户的诚信度,代表农户参与期货市场等。基于此,提出农民专业合作社应扩大业务内容,实现职能创新,培养或引进专业人才,制定相关期货操作规定,禁止从事投机交易;政府则应充分发挥其监督与服务职能,由此不断提高订单农业履约率。 相似文献

Using studied ECG sampling system, the analog signals of electrocardiograph is magnified and filtered,sending into the sampling card in computer, the sampling frequence is 1 000 Hz, the 5 minutes sampling signal is saved to hard disk. Using modern spectrum analysis method and FFT, the specific value VLF/HF of Heart Rate Variability (HRV)of 19 healthy individuals and 10 hyperthyroid is analysed .It is found that the significant difference of the specific value VLF/HF between the healthy individuals and hyperthyroid.There are no especial advantage and distinctness by using the modern spectrum analysis method or FFT to study balance the specific value VLF/HF between the healthy individuals and hyperthyroid. The result shows that the spectrum analysis method is relly an effective measure to analyze independence nerve abnormalities of hyperthyroid. 相似文献

构建高速公路景观评价体系和评价模型,探讨高速公路的景观评价方法。以哈大高速公路为例,从公路自身景观、公路沿线人文景观和公路两侧本底自然景观3方面进行评价、选取15个二级指标,55个三级指标的景观综合评价体系。参考有关的标准和研究资料制定二级指标的评价标准,利用层次分析法确定权重。采取景观综合指数法和模糊数学评价法对哈大高速公路总体景观质量进行了定量和定性评价。结果显示：哈大高速公路总体景观多数路段分数在6~7分之间,并且靠近哈尔滨和大庆2个城市路段分值高于中间路段,这可能与公路中间路段两侧的绿化和护理不到位有关。根据模糊评价法最大隶属度原则,哈大高速公路总体景观质量为“一般”等级,2种评价方法结果一致。鉴于各种评价方法的优点和缺点,采用基于AHP的综合指数法和模糊数学法适合高速公路景观质量的评价。 相似文献
