开放式创新社区中用户交互反馈对个体创新贡献度的影响

开放社区中的用户交互反馈是用户创新活动的重要组成部分，基于需求满足理论，研究其他用户反馈对个体创新贡献度的影响。结合典型开放式产品设计社区——Local Motors平台，采用数据挖掘方法，从数量、质量和情感3个方面研究开放式创新社区中FOU对个体创新贡献度的影响。结果表明，反馈数量和质量均对个体创新贡献度有显著影响，其中反馈次数对个体创新贡献度有显著正向影响，反馈率和反馈人员多样性对个体创新贡献度有显著负向影响，反馈长度和反馈支持文件对个体创新贡献度没有影响，正向情感倾向在用户反馈和个体创新贡献度之间无任何调节作用。     

京津冀协同发展下保定市建设用地对二三产业贡献的区域差异研究

作为京津冀核心城市之一,保定市土地供给与经济需求矛盾尤为突出。本文运用扩展后的柯布—道格拉斯生产(C-D)模型,测度2004-2013年保定市22个县(市)建设用地供给对二三产业的贡献,以期为保定市及各县建设用地科学管理提供依据。研究表明:2004-2013年保定市建设用地对二三产业的贡献值为12.69%,高于劳动力5.40%,低于固定资本78.47%;22个县市建设用地投入对二三产业发展贡献区域差异明显,这种差异主要受经济水平、区位条件、产业结构和资源条件等因素的影响。结论:保定市相关部门应因地制宜制定差异性建设用地供给指标,最大限度发挥有限土地资源产出水平,缓解土地供需矛盾。     

我国纺织品出口对经济增长贡献的实证研究

出口贸易是影响经济增长的重要因素。本文采用1980-2004年的数据,描述了我国纺织品出口的特点,并借助协整模型实证研究了纺织品出口对经济增长的影响,指出二者之间存在长期的动态关系。通过定量分析,发现纺织品出口对经济增长的直接拉动度和贡献率都较低,这是因为我国纺织服装行业一方面受宏观环境影响,另一方面自身竞争优势不足。本文经过研究,形成了对我国纺织品出口与经济增长之间关系直观而清晰的认识,并为无配额时代我国纺织业发展的后续研究提供了参考。     

Making effective pricing decisions

Pricing is one of the most complex decisions facing any company. Along with a lack of academic interest (especially among marketing academics) in the field of pricing, this complexity has contributed to the dominance of simplified, cost-based formulas when levying prices. This article offers an alternative approach based on the concept of contribution margin and the need to take into consideration only those costs that are related directly to a specific pricing decision, an approach that is especially useful when a company decides to change its prices. Moreover, an empirical study regarding the practical use of this approach is also presented.     

An Equity-based Redefinition of Underemployment and Unemployment and Some Measurements

An attempt is made in this article to redefine underemployment and unemployment without making reference to an excess supply of labor or any causal mechanism of unemployment. Instead, underemployment and unemployment are defined in terms of equity which draws upon the individual's preferences. A specific proposal is that underemployment be defined by the presence of contribution inequity relative to at least half the persons employed in a field that the underemployed person might prefer to move into. Empirically, most recent survey data on preferences for contingent and other nontraditional employment are used to illustrate the application of the concept. The major finding is that nearly 10 million Americans in the nontraditional workforce are underemployed.     

Using CRM to Manage Marketing Productivity

Abstract

The appropriate tool for measuring and managing marketing productivity is the present value of the total dollar contribution produced, divided by the total dollar value of the marketing effort expended to produce it. This ratio is referred to as the contribution return on marketing effort or CRM ratio. CRM integrated with activity based costing (ABC) and activity based management (ABM) systems, value analysis and value engineering (VA-VE) techniques offer a viable and practical foundation for managing customer relationship efforts and linking them to customer- and share holder value. The article offers a systematic approach for integrating contribution return on marketing (CRM) with customer relationship management (CRM).     

基于沉淀贡献的民办高校人才激励制度优化构想

民办高校与公办大学教师退休后享受同等待遇的政策目前没有得到解决，人才激励创新迫在眉睫。本文提出了沉淀贡献的概念，借鉴企业股票期权激励理论，试图设计一种为单位长期服务所做贡献的功绩评价机制，从而构建起对人才功绩评价与累积的长效激励手段。     

基于索洛余值法的装备制造业原始创新能力对经济增长的贡献率测度

通过引入索洛余值法并建立我国装备制造业生产函数模型,对1999-2009年我国装备制造业的科技进步贡献率进行测度和分析。结果表明:科技进步因素在装备制造业经济增长中日显重要,我国装备制造业单纯依赖于资本并不能取得长足发展,只有不断提高创新能力、尤其是原始创新能力,才能实现可持续发展。     

区域经济增长和科教投入的互谱分析

在分析区域经济增长与科教投入关系的基础上,依据互谱分析理论,对上海市1978—2007年公共科教投入和经济增长进行了实证研究。实证结果表明,科教投入对区域经济起到引领作用,并且它们之间存在非常紧密的相互关联性,同时计算出科教投入对经济增长的贡献率为13%。通过根据实证研究,并结合上海市经济的发展现状,提出了进一步促进区域经济增长的对策与建议。
