“微公益”行为、政府引导及其作用机制

随着互联网技术的快速发展普及,一种基于网络交互媒体的新的公益模式——"微公益"正快速兴起。"微公益"的出现体现了我国社会对公益的追求及对传统向善文化的传承,但"微公益"还处于起步阶段,需要参与其中的个行为主体共同努力以保障其健康成长。政府作为"微公益"行为的特殊参与主体,对"微公益"行为过程的健康成长的科学引导,将有效推动全社会精神文明的建设,从而为我国政治经济社会的全面繁荣添砖加瓦。     

Inter‐industry Inequality: An Important Source of the Urban Income Gap—Regression‐based Decomposition

基于回归方程的收入差距分解发现,1988年、1995年和2002年,行业间收入不平等对中国城镇居民收入差距的贡献越来越大,而且这主要是由一些收入迅速提高的垄断行业造成的。同时,区位、教育、所有制和职业类型以及是否有第二职业对收入差距的贡献也在提高,是否完全就业和年龄对收入差距的贡献明显下降。因此,缩小中国城镇收入差距,亟需打破劳动力市场进入壁垒和产品市场行业垄断。此外,减轻地区间的劳动力流动障碍、普遍提高劳动者的受教育水平等措施也将是未来政府缩小城镇收入差距的重要政策着力点。

Regression‐based decomposition of inter‐industry earnings differentials shows that in 1988, 1995 and 2002, inter‐industry earnings differentials made an increasing contribution to urban earnings inequality in China. The primary reason for the widening gap lay in monopoly industries. At the same time, geographical location, educational level, type of enterprise ownership, type of occupation and whether the individual had a second job also contributed to rising earnings inequality, while age and being fully employed made a decreasing contribution. Therefore, if China is to reduce the earnings gap it is imperative that we remove barriers to labor market entry and break down some monopoly industries in the product market. Additionally, reducing obstacles to the free movement of labor and improving workers' educational level should also be important elements of the government's strategy for reducing the urban income gap in future.     

产业集群背景下创业者社会网络构建影响因素实证研究

在创业研究领域,强调从外部社会环境来研究创业现象和创业问题的"社会学"视角正受到越来越多研究者的关注.而目前以在我国发展非常迅速的产业集群现象为背景的创业过程和创业行为方面的实证研究还很少见.以国内7个产业集群中的146位创业者为研究对象、应用组织心理研究领域中的行动理论等观点的研究,证实了创业者个人主动性(PI)、社会技能、成就动机和内控源是影响创业者社会网络构建关键因素的假设.此结论为后续开展相关研究提供了理论和实证基础,为创业者在实践中扩展社会网络提供了指导.     

Lead Time and Price Quotation Mode Selection: Uniform or Differentiated?

Firms in service and make‐to‐order manufacturing industries often quote lead times and prices to customers. We define uniform quotation mode (UQM) as the strategy where a firm offers a single lead time and price quotation, and differentiated quotation mode (DQM) is where a firm offers a menu of lead times and prices for customers to choose from. Both modes are followed in practice. Firms should determine which is more profitable. We classify customers into two groups: lead time sensitive (LS) and price sensitive (PS). LS customers value lead time reduction more than PS customers. We develop mathematical models of both quotation modes and analyze them to determine the most profitable mode under specified situations as well as the best lead time and price quotations within each mode. We find that DQM is dominated by UQM whenever PS customers have positive utilities from UQM or LS customers have positive utilities from DQM. Otherwise, which quotation mode is better depends on multiple factors, such as customer characteristics (including lead time reduction valuation and product valuation of a customer, and the proportion of LS customers) and production characteristics (including the desired service level and service or production cost).     

新时代高校思想政治理论课教师队伍建设的问题与对策研究

加强高校思想政治理论课教师队伍建设,是巩固和加强高校意识形态安全的关键环节,也是落实立德树人根本目标和推进高等教育内涵发展的题中应有之义.新时代思想政治理论课教师队伍建设应从坚定的政治方向、深厚的教学能力、较高的学术水平布局谋划.从总体情况来看,当前高校思想政治理论课教师队伍建设在队伍规模、年龄结构、综合素质等方面都存有明显短板.为此,要将其视作一项系统工程,坚持科学规划整体统筹,不断扩大队伍规模;坚持"外引进"和"内培养"相结合,持续打造高素质队伍;重视青年教师成长,促进教学科研协调发展.     

The Effects of Competitive Environment on Supply Chain Information Sharing and Performance: An Empirical Study in China

Information sharing in supply chains has become an important topic over the past decade. This study uses data from 617 Chinese manufacturing firms to investigate the relationships among competitive environments, supply chain information sharing (SCIS), and supply chain performance. The results of structural equation modeling analysis show that (i) international competition is positively related to all three types of SCIS whereas local competition is not significantly related to any of the three types, (ii) internal information sharing is positively related to external information sharing with suppliers and customers, and (iii) internal information sharing and information sharing with customers are positively related to superior supply chain performance, whereas supplier information sharing is not significantly related to performance. The findings enhance our understanding of the relationships among competitive environment, SCIS, and supply chain performance in Chinese manufacturing settings.     

Outsourcing Competition and Information Sharing with Asymmetrically Informed Suppliers

This paper studies an outsourcing problem where two service providers (suppliers) compete for the service contract from a client. The suppliers face uncertain cost for providing the service because they do not have perfect information about the client's type. The suppliers receive differential private signals about the client type and thus compete under asymmetric information. We first characterize the equilibrium of the supplier competition. Then we investigate two of the client's information sharing decisions. It is shown that less information asymmetry between the suppliers may dampen their competition. Therefore, the client does not necessarily have the incentive to reduce information asymmetry between the suppliers. We characterize the conditions under which leveling the informational ground is beneficial to the client. We also find that under the presence of information asymmetry (e.g., when the suppliers have different learning abilities), sharing more information with both suppliers may enhance the advantage of one supplier over the other and at the same time increase the upper bound of the suppliers' quotes in equilibrium. Consequently, the suppliers compete less aggressively and the client's payoff decreases in the amount of shared information. The findings from this study provide useful managerial implications on information management for outsourcing firms.     

在全球化语境中对传统武术与现代武术的文化解读

在全球背景下对传统武术和现代武术进行文化解读,不但有助于提高对其概念的理解,而且更能提高我们对两者的认识,传统武术是建立在我国传统文化基础之上的一种武术文化,而现代武术则是在西方体育文化影响下,在传统武术的基础上发展起来的一种竞技性体育文化。对两者的深入研究有利于武术事业的进一步发展。
