农民专业合作社对特色农产品品牌建设的作用

实施品牌战略是提高特色农产品的市场竞争力最有效的途径,具有十分重要的战略意义和现实意义。由于生产规模限制品牌的创建、农业标准化低、品牌主体缺失等因素,造成了当前我国特色农产品品牌建设中品牌档次不高、市场影响力不明显等问题。农民专业合作社在奠定特色农产品品牌形成的物质基础、形象识别,推广实施农业标准化以及保护品牌方面发挥重要作用。     

绿色产品开发的系统动力机制分析研究

绿色产品的开发和设计使生态环境与社会经济联结为一个协调发展的有机整体,促进社会实现可持续发展,成为当今产品生产的主导方向。通过探讨绿色产品开发的动力机制根源,从内部和外部两个方面分析企业绿色产品开发的动力因素,并阐述绿色产品开发的系统动力驱动机制,建立绿色产品开发的系统动力机制模型,分析其运行机制,以期为绿色产品开发决策提供科学依据。     

论《侵权责任法》规定的医疗产品损害责任

《侵权责任法》规定的医疗产品损害责任,从性质上来说,既是医疗损害责任的一个特殊类型,也属于产品责任的范畴,适用无过错责任原则。其中第59条规制的适用范围包括有缺陷的药品、消毒药剂和医疗器械以及不合格的血液,但此适用范围应予以界定。在此界定内,导致患者损害的医疗机构、生产者所承担的赔偿责任才是《侵权责任法》第59条规定的医疗产品损害责任。

Demand Systems Estimation With Microdata: A Censored Regression Approach

Demand systems estimation increasingly makes use of household-level microdata, mainly to measure the effects of demographic variables. Data based on these household-expenditure surveys present a major estimation problem. For any given household, many of the goods have zero consumption, implying a censored dependent variable. Techniques which do not take this censored dependent variable into account will yield biased results. We utilize a censored regression approach that is computationally simple, consistent, and asymptotically efficient. The results are then presented and compared with those obtained using an uncensored technique.

产品品种繁多类型企业投入产出表的处理思想与方法

对于生产装配性产品的机械企业，由于产品与原材料种类繁多，将造成企业投入产出表的规模庞大，致使投入产出表的编制、计算和使用产生诸多问题，甚至难以实现。为了控制表的规模，常采用将消耗量相近、生产工艺相近的产品合并的做法。但这种做法严重影响了投入产出表的精度和应用效果。因此，本文讨论了更为有效的解决这类问题的思想和方法。     

Measurement error, skewness, and risk analysis: coping with the long tail of the distribution.

Probabilistic risk analyses often construct multistage chance trees to estimate the joint probability of compound events. If random measurement error is associated with some or all of the estimates, we show that resulting estimates of joint probability may be highly skewed. Joint probability estimates based on the analysis of multistage chance trees are more likely than not to be below the true probability of adverse events, but will sometimes substantially overestimate them. In contexts such as insurance markets for environmental risks, skewed distributions of risk estimates amplify the "winner's curse" so that the estimated risk premium for low-probability events is likely to be lower than the normative value. Skewness may result even in unbiased estimators of expected value from simple lotteries, if measurement error is associated with both the probability and pay-off terms. Further, skewness may occur even if the error associated with these two estimates is symmetrically distributed. Under certain circumstances, skewed estimates of expected value may result in risk-neutral decisionmakers exhibiting a tendency to choose a certainty equivalent over a lottery of equal expected value, or vice versa. We show that when distributions of estimates of expected value are, positively skewed, under certain circumstances it will be optimal to choose lotteries with nominal values lower than the value of apparently superior certainty equivalents. Extending the previous work of Goodman (1960), we provide an exact formula for the skewness of products.     

论文化产品与“政府文化需求”

文章试图用经济学原理,以"需求"为基本范畴,分析社会文化产品生产、流通、消费的基本规律,揭示文化产品的价值和使用价值相统一的商品属性.文中特别提出了文化产品"政府消费"的概念,意在解决"公益文化"的市场定位问题,并为转变文化行政部门职能、改革现有文化事业单位体制、创新政府文化投入的拨款方式提供一定的理论依据.
