政府质量、市场化程度与现金—现金流敏感性——来自后金融危机时期的经验证据

在中国式经济增长进程中,政府作为"幕后推手"日益引发各界关注。政府的质量取决于政府所提出的制度安排,而企业行为是对政府所制定的制度的反应。本文以2009—2011年我国上市公司经验数据为样本,检验政府质量、市场化程度与现金—现金流敏感性间的关系。实证结果发现,随着政府质量的提升,企业运用内部现金流积累现金的倾向减弱,表现为现金—现金流敏感性降低。同时发现,这种变化在不同市场化程度地区的企业中会呈现不同的特征。具体而言,伴随政府质量的提升,市场化程度较低地区的企业受惠于制度环境的优化,其现金—现金流敏感性显著降低,而市场化程度较高地区的企业这一变化并不明显。本文为解释地方政府推出制度优化经济环境的微观机制提供了经验证据。     

Changes in risk and strategic interaction

In this paper we study the comparative statics of Nth degree stochastic dominance shifts in a large class of non-cooperative games. We consider symmetric equilibria as well as asymmetric equilibria in which the risk changes are idiosyncratic and not necessarily of the same stochastic order. Furthermore, we establish conditions for risk changes to produce multiplier effects on equilibrium strategies. Finally, we evaluate the comparative statics of stochastic dominance shifts in supermodular games, which may feature multiple equilibria and non-convex strategy sets.     

黑龙江省土地利用效益综合测度及耦合协调度研究

文章从土地利用经济、社会、生态效益入手构建适用于黑龙江省土地利用效益评价指标体系,结合熵值赋权与变异系数的综合确权法测算各城市土地利用经济、社会、生态效益水平及各指标权重,基于耦合协调度模型划分城市土地利用经济-社会-生态效益两两间耦合阶段与协调类型,研究表明:(1)黑龙江省西南部土地利用效益高于东北部,经济、生态、社会效益呈现明显的等级层次性,其中大庆与哈尔滨经济、社会效益居于首位,黑河与牡丹江生态效益最高;(2)黑龙江省生态-社会效益耦合协调强度大于经济-社会,经济-生态效益最低,多数城市处于拮抗耦合,仅伊春与黑河的经济-生态、经济-社会效益为低水平耦合;(3)黑龙江省西南部的协调程度整体高于东北部,其中仅哈尔滨与大庆土地利用效益为协调状态,其余城市均为失调。     

Coordination in retailer-carrier channels for long term planning

We study a retailer-carrier channel for the purpose of long term planning and coordination. Here, the term channel represents the business interaction between the retailer and the carrier. The retailer sells a particular item with price-dependent demand, whereas the carrier is responsible for transporting the item to the retailer's site. We characterize the profit functions of each channel member as well as the total channel profit. We consider two specific channel structures: (i) the centralized channel and (ii) the decentralized channel. Under the first channel structure, the goal is to set the retail price so as to maximize the total channel profit. Under the latter, the carrier and the retailer choose their own policy parameters, i.e., the freight rate for the carrier and the retail price for the retailer, so as to maximize their individual profits. We model the decentralized channel as a Stackelberg Game and propose a coordination mechanism between the retailer and the carrier in which the retailer signals a price multiplier to the carrier. We illustrate that this mechanism could provide win-win solutions for both parties and present analytical and numerical results on the efficiency of channel coordination. We demonstrate that coordination in retailer-carrier channels can be as promising as supplier-retailer channels. We also discuss the effects of retailer-carrier coordination on inventory levels.     

农民工住房满意度及其影响因素分析

农民工市民化是我国城镇化的推进器,而农民工住房问题是农民工市民化问题研究的重要内容。通过农民工大规模问卷调查数据分析发现,尽管住房条件较差,但农民工的主观感受好于预期,婚姻状况、收入等人口统计学因素和住房自身特征中多个因素对农民工住房满意度具有显著影响。     

Service innovativeness and the structuring of organizations: The moderating roles of learning orientation and inter-functional coordination

This paper aims to investigate the influence of organizational structure on service innovativeness by testing the moderating roles of learning orientation and inter-functional coordination. This helps to understand how organic structure influences service innovativeness when it is effectively leveraged with favorable organizational factors. Data were collected from 178 hotel managers and executives in Japan and moderated regression analysis was performed to analyze the data. Findings of the study suggest that higher levels of service innovativeness are positively related to higher levels of hotel business performance. In addition, organic structure makes a positive influence on service innovativeness and an increase in the levels of learning orientation boost the effectiveness of organic structure on service innovativeness. Moreover, the positive association between organic structure and service innovativeness become stronger when all firm’s functions make an attempt to cooperate and contribute to disseminating customers and competitors’ information in the hotels. These findings contribute to understanding how hotel service innovation is affected by service innovativeness, organizational structure, learning orientation and inter-functional coordination.     

高管政治背景与民营企业综合税负——基于政治关联的非线性影响研究

民营企业通过与政府建立良好的关系获得与国有企业同等待遇,税负是其中重要的一个方面。现有研究从线性的角度分析了政治关联对民营企业税负的影响,实际上,不同政治关联度对税负的影响方向是不同的。以2009-2011年沪深两市A股主板民营上市公司为样本,探讨政治关联是否影响企业税负以及政治关联度的变化对企业综合税负率的影响。研究发现,政治关联有助于降低民营上市公司综合税负率,且政治关联度与综合税负率之间存在倒U型关系。研究还进一步确定了政治关联度的拐点,为政府规制政策的制定提供参考。     

The effects of merchandise coordination and juxtaposition on consumers’ product evaluation and purchase intention in store-based retailing

Many retailers attempt to juxtapose and coordinate complementary products in their stores on the basis of key attributes because good coordination of complementary items can provide consumers with relevant information for their evaluation of individual products. In addition, the aesthetic appeal and the social impression that good coordination offers can be transferred to the products themselves. On the basis of these theories, the authors test the effects of merchandise coordination and juxtaposition (vs. separation) on consumer behavior using actual clothing items as stimuli in a laboratory setting. The authors find that coordination affects consumers’ evaluation of and purchase intention toward a target item only when the item is juxtaposed with a complementary item. This effect can be explained by the aesthetic response of consumers to and their social impression of a grouping of the items. Furthermore, in comparison with displaying the two items separately, juxtaposing them in a poorly coordinated manner appears to depress the target item's evaluation, though juxtaposing them in a well-coordinated manner does not seem to improve the evaluation.     

The Effects of Electronic Collaboration in Distributed Project Management

Abstact The emergence and widespread use of collaborative technologies for distributed project management has opened up opportunities for off-shore outsourcing and collaborative development. However, most tools and techniques for project management focus on on-site, long term relationships and sourcing strategies at a time when inter-organizational relationships are becoming more dynamic and geographically dispersed. This paper uses grounded theory to analyze data on virtual teams' projects. The analysis uncovers “effects” in the way in which distributed projects are managed. These effects relate to coordination, communication and adaptation to distributed electronic work environments. Following an analysis of these electronic collaboration “effects”, a model for distributed project management is presented.     

时空协同视角下的义乌中国小商品城演进历程分析

集贸式市场组织是一项极具“中国特色”的诱发性制度创新,是以某个固定场所为集聚地,以众多企业和个体商户为经营主体所形成的共享式交易平台。近年来,我国集贸式市场的组织形态及其功能都发生了重大变化,出现了与博览会、连锁经营、电子商务等现代流通业态相融合的趋势。在一个充分竞争的市场环境中,市场组织演进的结果体现出经济效率导向的要求。交易者将随着市场环境的变化,调整交易时间配置和空间分布的组合,以求达到交易成本最小化。本文以义乌中国小商品城为实证对象,以时间配置和空间分布为分析维度,运用交易费用经济学的理论方法,研究我国集贸式市场组织演进的动态过程。
