通过文献调查并结合案例的描述性分析,提出数字技术时代价值网络中不同行为主体之间的赋能内涵、关键维度以及基于赋能跨层次效应的价值共创行为分析框架。将"赋能氛围""主体赋能"分别作为价值网络中赋能的宏观维度和微观维度进行概念化。界定了两个维度的关键组成要素,分别包括信息共享、开放性结构、协同规则以及主体关系、资源整合和影响。构建了赋能的跨层次效应模型,分析了赋能的宏观-微观跨层次效应及其对价值网络生态和主体价值创造的影响。  相似文献

Numerous studies have examined factors influencing the likelihood of cooperative outcomes in nonzero-sum games, but there has been little study of the interaction between two of the most important: group size and pre-play cheap talk. We report results from an experiment in which groups of size between 2 and 15 play a one-shot multi-player threshold public-good game. In our random leader treatment, all group members select a suggestion (e.g., “Everyone should choose X”), with one randomly chosen to be broadcast to the group. In a choice only treatment, subjects choose suggestions but none is sent, and in a baseline treatment, there are no suggestions at all. We find a negative interaction between group size and this kind of communication: the beneficial effect of both suggestions overall and cooperative suggestions on cooperation, cooperative outcomes, and payoffs decreases sharply as the group size increases. We find a similar negative interaction in a follow-up treatment in which all group members’ suggestions are broadcast to the group. Our results suggest that care should be taken in generalising conclusions from small-group experiments to large groups.  相似文献

当前我国中小企业正处于经济转轨、社会转型期,在急剧变化和激烈竞争中将面临着严峻的考验与巨大的压力。这既阻碍了企业的发展,更严重危害着员工的身心健康。而EAP的实施能够有效地化解压力,提高工作效率。本文结合诸暨市当地实际情况,试从EAP在诸暨市中小企业的适用性及其产生的作用入手,进而探索视浙江省中小企业EAP的实施路径,希望为中小企业对员工建立有效的精神激励机制提供一些对策。  相似文献

在全球经济发展低碳化的趋势下,基于广州2003~2012年的统计数据,通过对碳排放进行计算,研究发现,不同产业部门碳排放情况变化明显,10年来,第一产业碳排放量比重较小且增加缓慢,第二产业碳排放量比重一直较大但增速放缓,第三产业碳排放量增长迅速且比重逐渐加大,2012年第三产业碳排放量首次超过第二产业。通过聚类分析,将工业部门内部行业划分为优先发展、重点发展、优化发展、限制发展和深化发展五类。最后,对不同的产业部门提出相应的政策建议。  相似文献

Based on a comparison of Berlin and Tel Aviv, this article investigates the ways in which ensembles of participatory instruments mediate between neoliberal urban regimes and political agency shaping differentially the meaning of participation and the types of claims that can be advanced. The article gives an overview of the recent history of both cities through the lens of participatory politics. Two in‐depth case studies further examine the relationship between participatory politics and claim making in each setting: the recent conflict over a social center in the district of Friedrichshain‐Kreuzberg in Berlin and the Levinsky tent city of 2011 in Tel Aviv. In the concluding section, the article suggests that, rather than assuming that participatory tools either co‐opt movements or can be appropriated by them, we need to rethink the relationship between participatory tools, rights and recognition, and ask how participatory structures and political agency constitute each other in interwoven dynamics.  相似文献

Recent theoretical and empirical studies have explored the effect of group membership and identity on individual decision-making. This line of research highlights that economic models focusing on the individual as the sole entity in the decision-making environment potentially miss critical features. This study takes this literature in a new direction by overlaying a field experiment onto a setting where groups have arisen naturally. Our experimental laboratory is large open air markets, where we are able to examine the effects of group membership on seller׳s collusive behavior as measured by prices and surplus allocations. This permits us to explore strategic implications of group composition. Empirical results illustrate the importance of group composition on pricing decisions, and show that deviations from Nash equilibrium are crucially related to group membership.  相似文献

Within the realm of urban logistics, Macário (2013) developed a hypothesis, denominated the Logistics Profile (LP) concept that suggests homogeneous groups of urban zones with respect to three dimensions, which could be used to analyze freight movement policy: (1) the social and built environment; (2) characteristics of the goods/products being moved; (3) characteristics of the deliveries at the receiver establishment. The concept was expected to ease the transferability of best practices in city logistics, by analyzing similarities and differences between zones. This research uses a quantitative methodology to apply the LP concept, and assess its potential, using the city of Lisbon as a case study. The analysis is focused on: (a) the extrapolation of freight trip generation per establishment and delivery characteristics from a sample of commercial establishments to the population within the case study, (b) proposing a methodology to test the LPs, (c) testing the existence of proposed LPs. Freight trips have been extrapolated using a Multiple Classification Analysis (MCA) model. Freight delivery characteristics were attributed to establishments from a sample-based probability distribution. LPs were tested using a two-step cluster analysis. Some LPs have been matched with clusters of case-study zones, subject to case study particularities. Profile overlap was not an issue and occurrences were expected. The testing showed that Logistic Profiles have the potential for being used as a departure point for urban freight planning and policy analysis.  相似文献
