产业集群、技术差距的双重影响与核心企业成长——以浙江为例

本文对集群中核心企业与配套企业之间的技术差距进行了研究,结果表明：技术差距对于核心企业规模成长与创新增长均有正向影响,但技术差距对核心企业规模成长具有非线性倒U型的支持作用,一定程度的技术差距实际上有利于核心企业规模成长,但技术差距拉得太大达到某个强度后则会逐渐妨碍核心企业的规模成长作用.而对比研究却发现,技术差距对核心企业创新并不具有这种非线性作用,技术差距的拉大对核心企业的创新增长并没有多少影响.因此,技术差距在核心企业成长中扮演了两面性角色,且核心企业成长需要在这种双重影响中找到某种平衡.     

网络嵌入性、技术创新和中小企业成长研究

在缺乏资源和核心竞争力的背景下,中小企业嵌入合作网络中进行技术创新,对提升企业成长性有重要意义。基于286家中国中小企业的调查数据,本文采取多元层级回归方法,对网络嵌入性、技术创新、技术动荡性与企业成长之间的关系进行了理论探讨和实证检验,试图揭示网络嵌入性、技术创新对企业成长的差异性影响以及转化机制,并对技术动荡性在网络嵌入性、技术创新与企业成长的关系中所扮演的调节作用进行实证分析。实证结果发现,网络嵌入性的网络中心度维度与中小企业企业成长呈显著的正相关关系,技术创新在网络中心度和企业成长关系之间起部分中介作用;技术动荡性负向调节网络中心度和技术创新的关系,正向调节技术创新和企业成长的关系。

符合环境规制下企业节能减排技术改进的演化博弈分析

在符合环境规制下,运用演化博弈论研究了企业节能减排技术改进行为的影响因素及影响机理。研究表明:企业改进节能技术所获得的市场增长率及掠夺采用现有节能技术企业市场份额越大时,企业双方改进节能技术的概率越大;政府提高节能技术改进的补贴系数及碳税税率对企业节能技术改进行为产生正向激励;现有节能技术碳排放量越大及改进后节能技术碳排放量越小均利于节能技术的改进;企业改进节能技术所支付的综合成本越小及现有节能技术带来的收益越大,企业改进节能技术概率就越大,反之企业改进节能技术概率就越小。最后,根据研究结论从培育绿色市场、增加节能补贴以及实施碳税政策等方面提出激发企业改进节能技术的政策建议。     

企业创新能否推动节能技术的运用?——基于中国制造业创新调查的实证分析

当前关于企业节能技术决策驱动因素研究相对较少,尤其很少关注企业创新行为对于节能技术决策的影响。本研究基于2009年中国制造业创新调查数据,在企业微观层面探讨了企业创新,包括产品创新、工艺创新和管理创新对企业节能技术决策的影响。结果表明,企业的创新行为,包括产品创新、工艺创新和管理创新均会对企业节能技术决策产生积极影响;企业能耗成本的差异会进一步调节企业创新行为与节能技术决策之间的关系,能耗成本高的企业在创新过程中更倾向于选择节能技术。从企业管理的角度来看,企业创新行为与节能技术投资行为根本目标相一致。对政策制定者来说,为更好地推动中国制造业节能,政府应当同时积极采取措施推动企业创新,尤其是管理创新。     

组织原型、创业领导力与科技创业企业成长路径及内在机理研究

借鉴组织原型理论和创业领导力方面的相关研究对科技创业企业如何成长的问题进行了探讨。通过对天津市科技创业企业的实地调研和对6家案例企业的深入分析,提出了科技创业企业的成长路径图及其内在成长机理。研究发现科技创业企业成长是在市场驱动、技术驱动、关系驱动3种组织原型相互转换基础上实现的动态非线性成长。3种不同的组织原型可以通过一段时间内创业企业所关注的关键战略活动、关键利益相关者和关键知识开发领域来判断。3种组织原型之间的相互转换并没有顺序性,但新的组织原型都是对先前组织原型的直接反应。进一步分析还发现,科技创业企业组织原型之间的转换过程是由创业者领导力推动的。

Students' Reactions to the Introduction of Videoconferencing for Classroom Instruction

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors.

Exploring Multiplexity: Social Network Structures in a Computer-Supported Distance Learning Class

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.     

The Role of Intermediating Institutions in the Diffusion of Electronic Data Interchange (EDI): How Industry Associations Intervened in Denmark, Finland, and Hong Kong

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies.     

How Electronic Publishers are Protecting Against Piracy: Doubts About Technical Systems of Protection

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.     

Rough Justice: A Statistical Assessment of ICANN's Uniform Dispute Resolution Policy

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP.

Monoculture Rubber Plantations Have Negative Ef ects on Controlling Splash Erosion

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence
