小小柠檬里的川渝合作

合作带来收益 Cooperation Brings Benefts 两地之间果农来往交流,提高了柠檬的生产规模和质量.两地相关部门也积极为果农们牵线搭桥,在生产资料供应、产品流通和加工领域为产业发展创造条件. "一斤柠檬卖七两",这是在柠檬果农里广为流传的一句老话.说的是采摘的柠檬,至少有三成是次果,卖不上价.这对川渝两地的果农都是一件头痛的事.随着2019年潼南引进重庆檬泰生物科技有限公司,这一问题得到了很大缓解.     

高管过度自信、研发投入跳跃与企业绩效——来自中国上市公司的经验证据

基于间断平衡理论和高阶梯队理论，以2007-2017年中国沪深两市902家制造企业为样本，实证分析研发投入跳跃对企业绩效的影响以及高管过度自信的调节作用。结果显示：研发投入正向跳跃和负向跳跃均有助于提升企业绩效，高管过度自信正向调节研发投入跳跃与企业绩效间的关系。引入高管过度自信这一重要高管特征作为调节变量，有助于重新认识管理者心理偏差对企业创新行为和绩效的影响，较好地弥补了研发投入跳跃对企业绩效影响机制的研究空缺，丰富了创新间断平衡理论研究。研究表明，企业应重视高管心理特征的影响并结合自身实际情况，合理选择研发投入策略以改善企业绩效。

Keiretsu centrality — profits and profit stability: A power dependence perspective

Prior studies compare keiretsu member firm and independent firm performance. Here, we use historical and power dependence perspectives to theorize that the Japanese keiretsu system primarily benefits the most central firms. We test this by examining the performance of two types of keiretsu firms (central firms and other member firms) within two types of keiretsu (horizontal and vertical). We hypothesize and find that: (1) central vertical keiretsu firms are more profitable than central horizontal keiretsu firms; (2) central horizontal keiretsu firms have greater profit stability than central vertical keiretsu firms; (3) central vertical keiretsu firms are more profitable than non-central vertical keiretsu firms; and (4) central horizontal keiretsu firms have greater profit stability than non-central horizontal keiretsu firms. Implications for managers and future research directions are discussed.     

建设工程业主与承包商招标后合同价格谈判的博弈分析

本文目的在于对业主和承包商在招投标后的合同谈判机理进行研究。对于经过招标的合同谈判，招标活动分两种情况，第一种情况为公开招标，第二种情况为邀请招标。对公开招标，本文指出了垄断性围标对于业主的风险，并且将存在寡头及多头竞争的公开招标并入邀请招标进行研究。在邀请招标情况下，假设业主根据各方报价和技术标得分，选定某一家单位作为合同谈判对象。对在各种信息对称、不对称情况下，对于双方的序贯博弈过程进行分析。     

Power Relations and Social Mix in Metropolitan Neighbourhoods in North America and Europe: Moving Beyond Gentrification?

Research on spatial segregation has suggested that social mix may be a temporary phase in class displacement, where relations between different groups are at best divided or ‘tectonic’, for instance in England. Political and policy discourses, by contrast, tend to uncritically valorize social mix as a means to breaking up concentrations of poverty and providing neighbourhoods with a middle‐class voice. In the literature, little attention has been paid to power dynamics in socially mixed neighbourhoods and the implications this may have for understanding theory and policy. The five articles that make up this symposium address the ways in which social and ethnic groups interact in major cities in Europe and North America and, as the title suggests, this involves taking into account power relations, domination and negotiation between the different groups. There is a need to connect the experience of the deployment of power within neighbourhoods (and between them) with the discussions of power mechanisms at work in wider urban processes.
