基于多元统计的城市设施综合评价研究

本文运用主成分分析和聚类分析两种综合评价相结合的方法,对我国31个省市2004年城市设施发展水平进行综合评价。首先,运用主成分分析法对各地区城市设施的水平进行排序,即综合排名;然后,运用聚类分析法对各地区进行划分、归类,反映出各地区在设施建设的各个方面在我国所处的大致水平以及存在的优势和不足。这对把握我国各地区城市的设施水平具有一定的参考价值,并可为各地区制定相应的城市设施建设发展战略提供科学的依据。     

社会化小农与乡村治理条件的演变——从空间、权威与话语维度考察

改革开放以来,小农快速社会化,逐步从传统小农演变为社会化小农。小农的社会化或社会化小农对乡村治理产生了革命性的影响,不仅改变了治理的基础、治理的资源,也改变了治理的条件。通过对小农社会化对乡村治理的空间、权威、话语的影响来考察乡村治理条件的变化可以看出:小农的社会化改变了乡村治理的空间、削弱了治理的权威、建构了新的话语体系。     

社会化网络虚拟社区中的合作经济

数字革命的演化,催生了一个即时、互动的全球性社会化网络,随着其网络应用的流行,用户成倍增长,虚拟社区创造合作经济的商业价值也日益凸显.本文多方位引用了营销学和传播学的经典理论,辅之以近年来最新的案例,分别从消费者与消费者、企业与消费者、企业与意见领袖三个合作维度阐释了社会化网络虚拟社区中最具生命力的三种合作经济模式.     

CEO humility,narcissism and firm innovation: A paradox perspective on CEO traits

We examine how two seemingly contradictory yet potentially complementary CEO traits—humility and narcissism—interact to affect firm innovation. We adopt a paradox perspective and propose that individuals can have paradoxical traits and that, in particular, humility and narcissism can coexist harmoniously, especially among the Chinese, whose philosophical tradition embraces paradoxical thinking and behaving. CEOs that are both humble and narcissistic are hypothesized to be more likely to have socialized charisma, to cultivate an innovative culture, and to deliver innovative performance. Two studies using multisource data involving 63 CEOs, 328 top managers, and 645 middle managers in Study 1 and 143 CEOs and 190 top managers in Study 2 support the hypotheses and point to new directions for studying CEO traits and their effects on firm outcomes.     

广西90后中学生社会化技能现状调查研究

中学阶段是人社会化过程中的黄金阶段和关键时期,中学生社会化技能状况不仅直接影响其个人未来的生存和发展状况,而且还将影响国家和社会发展对人才的需要。通过对广西9个地级城市的18个中学和9个县级中学的1800名90后中学生社会化技能状况调查,结果显示,广西90后中学生社会化技能总体处于良好的发展态势。但90后中学生社会化技能仍然存在值得引起学校、家庭和整个社会关注和解决的问题,不同群体和不同类别的中学生社会化技能存在较为明显的差异性。     

农户分工模式：从传统到现代

从分工的视角看,当今农户与传统农户存在显著的差异性。前者与传统中国乡土社会相适应,具有亲缘性、内敛性和单一性特征,形成闭合型的分工模式;后者则以商品化、市场化为契机,其分工模式逐渐向货币化、外向化和专业化转换,表现为开放型的分工模式。基于分工的视角,当今农户已经摆脱了传统小农生产方式的束缚,并逐渐融人到一个开放的、流动的社会化分工体系当中。     

Constraint-based model for the cyclic multi-hoists scheduling problem

This article presents a method for the resolution of a material handling scheduling problem. The case studied is a real industrial problem. It consists of finding a cyclic schedule for hoist movements in a treatment surface shop. In this kind of facility, several hoists are used for all the handling operations and they have to share common zones. Then it is necessary to control that there is no collision. The mathematical formulation of the problem is based on a combination of disjunctive constraints. The constraints describe either movement schedule or collision avoidance. The resolution procedure presented identifies all the collision configurations and then uses a branch and bound-like algorithm to find the optimal solution of a given problem. The language chosen for our implementation is the constraint logic programming language: Prolog IV, which is able to solve constraints with rational variables. It actively uses the constraint propagation mechanism that can be found in several languages.

生活方式变迁下的城市环境设施设计研究

城市环境设施设计与人们的生活方式息息相关。在生活方式变迁的情况下进行城市环境设施设计,应该深入分析生活方式的变迁对环境设施产生的影响,并利用基于群体文化学方法对人们的生活方式进行实地研究,进而得出人们的真实需求、具体行为模式和心理特征并由此来指导环境设施设计。此外,还应从更广泛的背景上建立人-设施-环境-城市的有机系统。     

Capacity Investment Under Responsive Pricing: Implications of Market Entry Choice*

We consider a manufacturer’s new market entry problem when it already has some established facility in its existing market. We consider two common market entry strategies: the export strategy and the foreign direct investment (FDI) strategy. In the export strategy the firm increases the capacity at its existing facility and subsequently allocates the output to the existing and the new market dynamically, depending on realized market conditions. The export strategy is a flexible strategy. In the FDI strategy, the firm invests in a dedicated capacity to serve the new market only. The FDI strategy is a (partially) dedicated strategy. We study these two strategies from a planning perspective, that is, how the firm’s strategy choice influences the optimal capacity levels. We find that the firm’s strategy choice can significantly impact the optimal capacity investment levels. We prove, for example, that the firm may enter the new market in the export strategy but not in the FDI strategy, even if the capacity investment cost is identical in the existing and the new market. In addition, we prove that the firm may invest a strictly higher capacity level in the export strategy than that in the FDI strategy. We also prove that new market entry in the FDI strategy may strictly decrease the firm’s supply to its existing market but this is not so in the export strategy, and hence policy makers should carefully consider the implications of trade regulations on firms’ market entry choices.
