我国本土高技术企业技术创新渠道源研究

本文结合技术推动理论和市场拉动理论,把技术创新源分为三种具有技术推动效应的渠道源(内部R&D、技术转让、技术溢出)和一种具有市场拉动效应的渠道源(用户创新反向传播)。基于我国高技术产业的面板数据,本文使用广义矩方法在一个统一的框架内考查了各种技术创新渠道源的有效性。实证证据表明,我国本土高技术企业的有效技术创新渠道源包括:(1)内部R&D,(2)国外技术转让,(3)产业内三资企业技术溢出,(4)产业间三资企业技术溢出,(5)国外用户创新反向传播,(6)国内用户创新反向传播。我国本土高技术企业高度依赖国外的核心技术和关键设备,这使得国内技术转让和产业间本土企业技术溢出不能成为其有效的技术创新渠道源。因此,我国政府应当制定更多优惠政策强化本土高技术企业的自主创新,并促进高科技成果的商业化。

论3C产业的技术伦理

高技术产业迅速发展,人们在物质方面的享受达到了前所未有的高度,不过技术发展并没有真正将我们带到了最佳状态。本文通过时比汽车历史上的有计划的废止制,时3C产业的行业特征、营销策略、消费者的消费心理等方面进行分析,从而对技术伦理作进一步思考。     

基于不同特征FDI的溢出效应比较研究

在中国成为外商直接投资(FDI)流入最多的国家之一，同时流入中国的FDI中又有近2／3左右流入中国的制造业的情况下，本文检验了外商直接投资对中国制造业的溢出效应。比较区分了产业内和产业间的溢出效应。分别研究了不同类型的FDI(来源于香港、台湾和澳门的FDI和来源于西方国家的FDI)对当地企业产生的不同影响、当地不同类型的中国企业从FDI外溢效应中受益程度的差异、外资参与程度的不同对溢出效应的影响，并在此基础上提出相关政策建议。     

基于策略消费者的退货产品再销售渠道选择研究

针对退货产品再销售渠道选择问题,基于策略消费者延迟购买行为,构建了消费者效用需求函数,从制造商视角,考虑了制造商直销和清理商分销两种再销售渠道,通过对比分析不同决策下制造商的利润,得到不同条件下退货产品再销售的最优渠道。研究表明:策略消费者比例、策略消费者折扣估值系数决定清理商分销渠道是否存在;在保证其存在的前提下,当策略消费者折扣估值系数在某区间内时,若清理商分销渠道相对制造商直销渠道的分销效率偏小,制造商选择清理商分销渠道,若清理商分销渠道相对制造商直销渠道的分销效率偏大,制造商选择直销渠道。     

环境规制是否倒逼了创新驱动的地区产业转型升级？

   本文借助于“两控区”政策冲击,选取1994—2010年中国地级市面板数据和国家专利数据,运用倍差法,研究了环境规制对地区产业转型升级的影响及其机制。研究发现：环境规制显著地促进了地区产业转型升级,且在长期内其政策效应呈现出逐渐减弱的趋势。使用不同的产业转型升级指标等稳健性检验表明,我们的结论基本不变。同时,政策效应存在地区异质性,即它只是显著地促进了中部地区的产业转型升级。进一步机制研究发现：环境规制并不是通过资本深化渠道和外资溢出效应渠道,而是通过技术创新渠道倒逼了地区产业转型升级。

根据联合国贸易数据库统计数据,分析了中国高技术产品的贸易现状,采用GL指数、边际产业内贸易指数,从不同角度测度和分析了中国高技术产品的产业内贸易水平,运用面板数据对国家层面的影响因素进行了研究。结果发现,中国高技术产品产业内贸易大而不强,产业内贸易结构不均衡,急需大力发展航空航天等产业。中国与贸易伙伴的人均收入差距、技术差距和外商直接投资都是影响产业内贸易发展的因素,其中人均收入差距和产业内贸易具有显著的负相关性,其余因素根据贸易伙伴的不同而有所差异,并根据研究结果提出了相关建议。     

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.

The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.     

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.     

Low doses of a red wine ingredient figh diabetes in mice

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said.     

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
