农户化肥减量行为动力机制研究基于山西运城地区苹果种植户调研

目的 在当前化肥施用过量并造成严重面源污染的背景下,需要厘清农户化肥减量行为困境并进行合理的机制设计,实现化肥施用量“负增长”的目标。方法 文章引入农户从众性行为、政府内源激励、外源激励,构建农户化肥减量行为动力机制理论模型,并通过演化博弈理论和结构方程模型进行理论和实证分析。结果 减量内生动力,农户从众性行为、减量禀赋间接正向影响减量行为,减量意向具有中介效应;减量外生动力,政府内源激励直接正向影响减量行为,外源激励在减量意向与减量行为之间发挥积极调节作用;仅在政府提供双向激励,策略（双向激励—化肥减量）才能演化为稳定状态。结论 增强农户减量内生动力,完善基层农业技术推广体系建设和建设标准化果园,充分发挥减量外生动力,加大政府对化肥减量增效技术的宣传教育,尽快落实生态补偿等减量政策。

Can time soften your opinion? The influence of consumer experience valence and review device type on restaurant evaluation

The objective of this study is to investigate how review temporal distance influences the conformity of consumer restaurant review ratings. By employing an innovative dataset pairing consumer reservation records and consumer online reviews, the findings of this study indicate that (1) in general, temporal distance has a positive influence on restaurant evaluation conformity; (2) consumption experience valence moderates the influence of review temporal distance on restaurant evaluation conformity, with a negative dining experience strengthening the positive effects; (3) review device moderates the influence of review temporal distance on review conformity, with reviews posted via mobile devices weakening the positive effect of temporal distance; and (4) compared to reviews posted via PCs, mobile reviewers appear less likely to be influenced by prior reviews. Findings from this study provide practical insights for restaurants’ management of online reviews.     

Signaling about Norms: Socialization under Strategic Uncertainty

We consider a signaling model in which adults possess information about the dominant social norm. Children want to conform to whatever norm is dominant but, lacking accurate information, take the observed behavior of their parents as representative. We show that this causes a signaling distortion in adult behavior, even in the absence of conflicts of interest. Parents adopt attitudes that encourage their children to behave in a socially safe way (i.e., the way that would be optimal under maximum uncertainty about the prevailing social norm). We discuss applications to sexual attitudes, collective reputation, and trust.     

国债规模之我见

从1998年开始实施的以国债政策为主体的积极财政政策对我国经济发展功不可没。但是国债规模的日益扩大最终也可能产生其负面影响,因此对国债规模的研究日益受到我国经济学界和财政学界的广泛重视。同时,对国债规模的大小也是争论不休,存在的分歧较大。本文从对国债规模指标体

To be different,or to be the same? It’s a question (and theory) of strategic balance

This paper addresses the performance consequences of firm‐level strategic similarity. Past research observed that firms face pressures to be different and to be the same. By differentiating, firms reduce competition. By conforming, firms demonstrate their legitimacy. Both reduced competition and legitimacy improve performance. This paper begins building a theory of strategic balance by synthesizing the differentiation and conformity perspectives. The theory directs attention to intermediate levels of strategic similarity where firms balance the pressures of competition and legitimation. Empirical support for the theory is found in a longitudinal study of commercial banks. Several suggestions for developing a theory of strategic balance conclude the paper. The theory’s major implication is that firms should be as different as legitimately possible. Copyright © 1999 John Wiley & Sons, Ltd.

社交网络持续使用：从众行为和习惯调节作用

文章通过探究在社交网络服务（SNS）情境下从众行为和习惯对用户持续使用意向的影响来拓展ECM-IT模型。结合从众行为和习惯的相关研究,提出了从众行为和习惯调节感知有用性和使用满意度对用户持续使用意向的影响的研究模型。通过问卷调查的方式收集了202份中国社交网络服务用户的数据,并利用实证研究方法进行数据分析。研究结果表明,从众行为增强了感知有用性对用户持续使用意向的影响作用;习惯减弱了使用满意度对持续使用意向的影响作用。最后,提出了文章的管理启示以及对后续研究的一些建议。     

滇藏川交接地区域经济一体化初探

滇藏川交接地是我国西南部跨越滇、藏、川三省区的交接边区,同时也是“中国香格里拉生态旅游区”的主体区域。区内少数民族众多,经济发展水平滞后。文章首先对滇藏川交接地进行背景分析,结合历史上及目前该区域内的经济联系,对其经济一体化的形成基础和特色产业开发进行研究,最后根据障碍分析提出相应对策。研究表明区域经济一体化有利于打破三省行政区划的限制,大力促进区际联系和产业分工合作,整合各地资源、区位优势,从而加快该地区的经济发展,在此基础上构建的多民族聚居区经济一体化是我国和谐社会构建的重要组成部分,也是民族经济社会持续健康发展的必由之路。
