工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.     

劣势耐用品厂商的产品质保期与质保服务投入策略研究

在实际中，消费者购买耐用品时均同时获得厂商提供的质保服务，由于产品质保服务影响着消费者的产品使用效用，因此耐用品定价、质保期和产品质保服务投入是影响厂商利润的主要因素。考虑双寡头市场环境下，建立微分博弈模型讨论单位产品质保服务投入和产品质保期对双寡头厂商均衡价格的影响。结论表明双寡头厂商的单位产品质保服务投入越高、质保期越长，均衡价格越高；但单位产品保服务投入与质保服务对消费者效用影响系数的关系影响着竞争对手在均衡价格的变化趋势；劣势的低质量厂商可以通过增加单位产品质保服务投入策略或延长质保期的策略实现在均衡下与高质量厂商以同等价格销售耐用品，但劣势厂商增加单位产品质保服务投入策略要优于延长质保期策略。最后，利用数值分析进一步验证了所得结论的有效性。     

重识新诗“诗性”观——纪念新诗诞生一百周年

新诗已年届百年,但新诗的文体标准抑或诗性特质仍然没有一致之论;既往的探索虽然丰富多样,但提出的观点大多属于进乎技矣的大道之论,很难将它们落到实处;问题的症结在于诗人的创作、批评家的阐释与读者的欣赏之间出现了话语装置的混乱与错置现象,无法充分揭示新诗艺术及精神的成就与奥秘;就当下而言,我们可以甚至必须从现代汉语言及现代中国人的实际情况出发,以"情智双修"为轴心,在秉承及转换中外诗艺的基础上,建立起对个人性、公共性、神圣性、世俗性、现代性及后现代性体验都各有探索的新的诗性标准。     

失智老人的非药物治疗方法（下）

本期我们继续谈谈治疗失智老人在日常生活中可以运用的“非药物治疗方法”： 艺术治疗 艺术治疗是一种结合创造性艺术表达和心理治疗的助人专业。英国艺术治疗家协会这样定义它：艺术治疗是一种治疗的方法，在艺术治疗工作者的协助下，通过绘画、塑造等艺术媒材，从事视觉心象表达，借此心象表达把存于内心而未表达的思想与情感，向外呈现出来。     

农民工返乡创业投资演化博弈分析

返乡精英农民工与普通农民工创业是复杂的博弈竞争过程,受农民工初始财富、经济投资规模、经济投资与社会资本投资边际收益与边际成本、经济投资与社会资本投资竞争拥挤、政府政策和在乡农民竞争等因素的非对称影响制约。众多因素不仅影响两者创业投资均衡策略、均衡水平、均衡变化方向与速度,而且影响其创业投资路径选择,导致两者投资具有多均衡性、多路径性、非对称性、初态依赖性与阶层分化性,创业投资将呈现出结构失衡状况。政府应该采取多样化政策措施,统筹平衡推进返乡精英农民工、普通农民工与在乡农民创业可持续发展。     

泸沽湖之美

正泸沽湖位于云南丽江宁蒗县北部,泸沽湖古称鲁窟海子,又名左所海,俗称亮海。湖中各岛婷婷玉立,形态各异,林木葱郁,翠绿如画。身临其中,水天一色,清澈如镜,藻花点缀其间,缓缓滑行于碧波之上的猪槽船和徐徐飘浮于水天之间的摩梭民歌,使其更增添几分古朴、几分宁静,是一个远离嚣市,未被污染的处女湖。
