知识员工绩效考核方法的探索

知识员工的绩效考核方法应适于知识员工的绩效特征。绩效考核方法可根据考核结果受考核者决策影响程度的不同,分为主观考核法与客观考核法两类。每一种主、客观考核法在知识员工的绩效考核中各有利弊且考核的侧重点各异。今后的研究可以将重点放在探索一种结合主观考核法与客观考核法优势的绩效考核方法,或者尝试将一种主观考核法与一种客观考核法有机结合,以实现对知识员工科学、高效地绩效考核。     

An integrated model for analyzing the development of the 4G telecommunications market in Taiwan

Previous studies of development trends in the telecommunications industry have estimated market potential but have seldom integrated analyses of customer preferences and macro-environmental factors (political, economic, social, and technological analyses). In order to more accurately analyze 4G technological trends and market penetration and provide implications for businesses and policymakers, we use conjoint analysis to analyze customers' preferences for telecommunications technology and integrate the results with data from scenario analysis and the Delphi method to address possible scenarios for the development of 2G, 3G, Worldwide Interoperability for Microwave Access (WiMAX), and long-term evolution (LTE) in Taiwan. We then use the innovation diffusion model to forecast the sales volume for these four technologies in Taiwan over the next 10 years. Finally, we provide suggestions for policymaking and strategic actions for 4G stakeholders.     

Social media affordances in entry‐level employees’ socialization: employee agency in the management of their professional impressions and vulnerability during early stages of socialization

This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.     

空间视角下R&D投入对区域创新能力的影响研究——基于科技政策组合的调节作用

基于知识生产函数模型和创新地理学理论,本文利用我国30个省(区、市)2008~2020年的面板数据,通过空间计量模型实证分析R&D投入对区域创新能力的影响及空间溢出效应,并从政策目标与政策工具的耦合协调性视角理解科技政策组合,分析科技政策组合的调节效应。研究发现,我国省域创新能力呈现由东向西逐渐减弱的“梯形”分布特征;R&D资金和R&D人员对于本地区域创新能力提升具有显著的正向影响,但空间溢出效应均不显著;科技政策组合正向调节R&D投入对区域创新能力的促进作用。对此,国家应制定适宜的区域创新战略,地方政府应探索差异化创新驱动发展路径并提升科技政策组合的耦合协调性。     

国外环保投资基金经验对我国的启示

环保投资基金在国外不断发展壮大,主要模式有政府引导型基金、风险投资型基金和股票投资型基金等.国外政府制定政策支持环保投资基金的发展与运作,发挥政府的引导作用,明确基金的管理权限,制定严格的基金项目选择标准,实现环保领域投资多元化.我国应借鉴国外经验,通过设立政府引导型环保基金、制定环保基金的优惠政策、制定环保基金投资规范和扩展环保基金投资领域等方式,发展我国的环保投资基金.     

Relation between time-series and cross-sectional effects of idiosyncratic variance on stock returns

Consistent with the post-1962 US evidence by Ang et al. [Ang, A., Hodrick, R., Xing Y., Zhang, X., 2006. The cross-section of volatility and expected returns. Journal of Finance 51, 259–299], we find that stocks with high idiosyncratic variance (IV) have low CAPM-adjusted expected returns in both pre-1962 US and modern G7 data. We also test in three ways the conjecture that IV is a proxy of systematic risk. First, the return difference between low and high IV stocks – that we dub as IVF – is a priced factor in the cross-section of stock returns. Second, loadings on lagged market variance and lagged average IV account for a significant portion of variation in average returns on portfolios sorted by IV. Third, the variance of IVF correlates closely with average IV, and the two variables have similar explanatory power for the time-series and cross-sectional stock returns.

Integrating decomposition approaches for the analysis of temporal changes in economic structure: an application to Chicago's economy from 1980 to 2000

This paper presents an attempt to integrate two flow decomposition methods to analyse temporal changes in a region's economic structure. The two methods of structural analysis are push–pull decomposition analysis and structural Q-analysis. Push–pull analysis presents a quasi-optimization decomposition of a set of matrices with actual intersectoral economic flows into a weighted set of matrices, while structural Q-analysis provides a form in which the structure of these decomposed flows can be considered. The paper provides an expository application to Chicago's economic structure over the period of 1980 to 2000, to reveal a complementary perspective of hollowing-out the production process in the Chicago economy that was identified in previous studies.
