基于IAD延伸决策模型的农户征地意愿研究

基于奥斯特罗姆IAD模型的延伸框架,通过广东省21个市(县)2013年的调查数据,首先运用二元logistic整体回归模型对征地制度改革中农户的征地意愿进行研究,进而发现细分已征地农户与未征地农户的意愿差异并差别分析的必要。研究结果显示:除了一般的户主特征变量、征地补偿标准变量外,程序变量和认知改革变量对已征地和未征地农户的征地意愿影响尤其显著,但二者在近乎均质的行动舞台中,基于对事前最终行动结果信息的感知和预测,在征地意愿上表现出了不同的变量特征,数据分析表明未征地农户是以征地农户的最终行动结果(决策前)作为决策参照,以制定激励和预期收益调整征地意愿决策。另外,回归模型显示在征地意愿的影响因素中,程序公正(协议征地)要优于货币补偿,农户对土地财产性权利分配的关切不是征地制度改革自身所能解决的。     

品牌延伸战略的应用研究

品牌延伸是品牌经营战略的重要内容之一。它有利于新产品的市场拓展、降低新产品市场导入费用、产生协同效应、企业创名牌、实现规模效益。但是品牌延伸的有效性受到顾客认知、与延伸产品之间的相关性、新产品自身的成功因素、市场的需求量与竞争状况、品牌实力、企业的品牌战略等因素的影响。因此,要树立品牌战略思想,选择合适的品牌延伸形式,以取得品牌延伸的实际效果。     

Extendible stock loan

In this paper, the model of extendible stock loan with forbearance is proposed. The loan is extendible, so as to prevent immediate losses or to prevent subsequent price drop; while the forbearance is granted only when the pledged share’s value is above threshold, so as to mitigate the risk-taking behavior induced by the extension. The non-synchronization of the liquidation of insolvent stock loans also alleviates the downward leverage spiral in a market downturn. Numerical analysis shows that fair extendible stock loan rates increase with the forbearance level as well as extension period, and loan rates are quite sensitive to the change of asset volatility and debt ratio. For lenders waiving the interest rates during extension period, their burden grows with extension rapidly when they grant looser forbearance and when asset volatility or loan-to-value is higher. Some suggestions are made accordingly. First, lenders offering uniform extendible loan rate can let borrowers choose between looser forbearance with shorter extension, or tighter forbearance with longer extension. Second, if the loan rate is priced fairly, lower margin requirement can only be accomplished with tighter forbearance. More looser forbearance worth higher rates.     

Smartphone-based agricultural extension services and farm incomes: Evidence from Zhejiang Province in China

Smartphone use in rural China has grown rapidly, leading to the fast development of smartphone-based agricultural extension services. However, there is limited research on the income effects of smartphone-based agricultural extension services in rural areas. In this study, we analyze the causal effects of smartphone-based agricultural extension services (“Zhe'yang'shi” WeChat application as an example) on farm incomes in Zhejiang, China, using a staggered difference-in-differences method with panel data from 400 crop farmers. Our results show that adopting smartphone-based agricultural extension services increases farm income from soil testing formula fertilizer fields by 15.39% and total farm income by 16.31%.     

The Relationship Between Consumer-Brand Identification and Brand Extension

The present research aims at examining the role of consumer-brand identification (CBI) in attitude toward brand extension regarding the congruency between the values of consumers and brands. In this way, the benefits of CBI to consumers and brand managers are outlined. This research has been conducted through designing a survey and collecting data through a questionnaire. For data mining and investigating the model, the SEM approach is implemented. According to the findings, high levels of CBI lead to positive attitudes toward the brand extension, and that value congruity positively impacts this relationship. The results outline that CBI impacts fit and tie in separate ways, so that CBI effect on fit is more substantial. Furthermore, according to the results, in comparison to the role of tie, the role of fit is more significant in predicting attitudes toward brand extension. The sample from university students is appropriate for testing theory, but limits generalizing the results of the research. In addition, this research has studied one product category and is limited in this perspective. The findings have remarkable recommendations for implementing brand extension as they emphasize the role of perceived fit. Moreover, by reexamining CBI in a less known market, the research has outlined its positive outcomes for firms. This research has used perceived tie in a brand extension context and, similar to perceived fit, has implemented it as another factor to predict attitude toward brand extension. In addition, this research is unique, as it has investigated CBI in a new context.

北京实施免耕及经济补偿问题研究

免耕是保护性耕作的一种措施,能有效地防治地表起沙,具有很好的保水保墒效应。本文通过实地调研、和农民及相关部门访谈,指出北京推广免耕主要存在农机具、粮食产量、农民接受程度、现行管理体制以及免耕技术等方面的问题。要顺利推广免耕措施,还需要大量宣传,提高农民的接受程度,并实施"技术补贴+生态补偿"的经济补偿措施。经济补偿可以按照机具投入2600元/hm2来折算补偿给地方政府,按照秸秆效益4500元/hm2来补偿农户。同时,还应通过建立和完善"农业环境保护补偿基金"和"农业环境保护组织"等,以扩大资金渠道,加强组织管理,保证免耕的可持续实施。     

油气管道第三方破坏风险等级划分方法研究

基于油气管道第三方破坏半定量风险评估,利用已获得的大量的半定量风险值,结合物元与可拓集合理论对管道第三方破坏风险等级进行划分。通过输入第三方破坏评价指标不同的评分值,运用层次分析法对各评价指标权重赋值,计算可拓集合关联函数得到相应的风险等级,进而为管道运营单位风险管理提供理论上的决策依据。该分析方法具有较强的普适性与可操作性,能很好地结合评价人员的专业知识,综合评价管道第三方破坏的风险水平,使油气管道第三方破坏风险等级的划分更加科学合理。

Do Formula or Competitive Grant Funds Have Greater Impacts on State Agricultural Productivity?

This article examines the impact of public agricultural research and extension on agricultural total factor productivity at the state level. The objective is to establish whether federal formula or competitive grant funding of agricultural research has a greater impact on state agricultural productivity. A pooled cross-section time-series model of agricultural productivity is fitted to annual data for forty-eight contiguous states over 1970–1999. Our results show that public agricultural research and agricultural extension have statistically significant positive impacts on state agricultural productivity. In addition, Hatch formula funding has a larger impact on agricultural productivity than federal competitive grant funding, and a reallocation of Hatch formula funds to competitive grant funding would lower agricultural productivity. This seems unlikely to be a socially optimal policy. Furthermore, from a cost–benefit perspective, our study shows that the social marginal annualized real rate of return to public resources invested in agricultural research is 49–62%, and to public agricultural extension, the rate is even larger.
