‘Who Knows What?’ in New Venture Teams: Transactive Memory Systems as a Micro‐Foundation of Entrepreneurial Orientation

The increasing importance of entrepreneurial behaviour has led scholars to embrace the idea that an entrepreneurial orientation (EO) is an important predictor of firm performance. While EO occupies a central position in strategic entrepreneurship research, scholars have yet to explore its origins in new ventures. Drawing on the knowledge‐based and cognitive views, we theorize that a new venture team's transactive memory system is a cognitive mechanism that spurs the development of an EO. In a field study of high‐tech new ventures in China, we examined the relationship between venture teams’ transactive memory systems (representing the distribution, integration, and utilization of the teams’ knowledge) and EO and the moderating influence of team‐, firm‐, and environment‐level factors. We found that the transactive memory system of a new venture team enhanced their EO and that this relationship was positively influenced by intra‐team trust, the structural organicity of a venture, and environmental dynamism. Our findings provide novel insights into the micro‐foundations of TMS in developing an EO in new ventures.     

Object detection based on visual memory: a feature learning and feature imagination process

ABSTRACT

Visual memory plays an important role for the human’s visual system to detect objects. The features of an object stored in the visual memory have much lower dimensions than the features contained within an image. We simulate the visual memory as a feature learning and feature imagination (FLFI) process to build an object detection algorithm. The method is constructed by a bottom-up feature learning and a top-down feature imagination. The proposed object detection method is tested using publicly available benchmark data sets, and the result indicates that it is fast and more robust.     

基于灰色关联分析的企业IT应用水平提升路径研究

在实证调研的基础上,应用灰色关联理论,对企业的管理制度能力和流程管理能力与IT应用水平进行灰色关联分析,发现企业IT应用水平不同阶段,这两种能力与IT应用水平的关联度存在差异,表明企业IT应用发展规律在不同IT应用阶段相对应的制度能力和流程管理能力不同。由此,提出企业在选择提升IT应用水平路径上应当关注在不同时期与IT应用水平相对应的制度能力和流程管理能力的培育和强化。     

基于排队论的动态多项目资源配置方法研究

在大规模定制环境中,制造企业多以项目的方式对产品的设计、制造等全过程进行管理。在这种环境下,项目及其资源具有动态性。针对其动态性,对动态多项目资源配置问题进行了描述,并提出了基于排队论的动态多项目资源配置模型。最后根据自适应遗传算法给出了该模型的求解算法,并进行了实例仿真分析。结果表明,在不影响完工日期的前提下,该方法可以减少资源配置费用。     

我国承销商利用分析师报告托市了吗?

学术界对于我国IPO市场是否存在承销商托市行为一直存在争议。本文通过搜集新股上市一年之内的分析师报告数据,系统考察了我国承销商利用分析师报告进行托市的行为特征,以及投资者对于承销商分析师具有托市性质报告的市场反应。结果发现:(1)承销商会利用乐观、但偏颇的分析师报告为市场表现不佳的新股进行托市,但这一现象在新股上市90天后消失;(2)声誉机制在新股解禁期后才能有效约束承销商利用分析师报告托市的利益冲突行为;(3)市场投资者总体上能够识别承销商的托市意图,并对承销商分析师报告的系统偏误进行自我调整。本文的研究不仅为我国承销商是否存在托市行为提供了新的直接性经验证据,而且有助于市场各方洞悉分析师报告背后的利益冲突,同时也为监管部门出台相关的规范政策提供了新的决策参考。     

A Golden Formula in Neoclassical‐Growth Models with Brownian‐Motion Shocks

In the paper, a Golden Formula, which does not depend on the specification of production and preference functions, is established to reveal that time‐average of the growth rate of optimal capital accumulation will converge to a constant, which is endogenously determined by relevant parameters, almost surely. The Golden Formula naturally implies surprisingly interesting and also intrinsic economic relations between some important macroeconomic variables; for example, it serves as a direct bridge between the modified Golden Rule and the modified Ramsey Rule. Furthermore, it indeed subsumes and hence substantially extends the classical Golden Rule in deterministic theory.     

我国风力发电项目投资风险评价——基于支持向量机模型

在分析我国风力发电项目投资风险并建立其评价指标体系的基础上,将支持向量机模型用于风力发电项目投资风险评价,全面衡量风力发电项目面临的经济风险、技术风险、政策风险等。支持向量机方法很好地解决了风力发电项目样本数据缺失、评价主观性问题。实证分析结果表明,利用支持向量机模型评价风力发电项目的投资风险,具有一定的适用性和准确性。     

开征累进物业税的战略构想

地价过快上涨和投机需求旺盛是造成房价不合理上涨的两个重要原因。在城乡同时开征累进物业税可以解决上述问题。累进物业税的开征对象包括城市住宅、城市已出让土地及农村住宅。在城乡共同开征物业税的基础上,将物业税归为地方税种,在中央和地方之间重新分配土地出让金,弱化地方抬高地价的内在冲动。     

广西农垦产业园区建设融资问题探讨

产业园区要实现其运营目标和服务功能,良好的基础设施是首要具备的条件。基础设施建设资金的不足和融资渠道的匮乏,影响并制约了广西农垦产业园区的开发与建设。为了促进农垦经济又好又快地发展,提高投资效率,应当针对经营性、准经营性及非经营性基础设施项目的各自特点选择适宜的融资模式,并不断探索、发展新型融资模式,拓宽融资渠道,促进农垦产业园区的发展。     

基于战略贡献的岗位评价研究

岗位评价为企业战略发展和获取核心竞争力提供了非常明确的操作方向.然而现行岗位评价方法过多关注工作本身和所需知识技能,缺乏将岗位价值与公司战略紧密联系的逻辑关系,忽视了岗位评价的战略性思考.文章从岗位对战略贡献的视角入手,选择平衡计分卡作为战略实施的基础工具,构建出基于战略贡献的岗位评价因素研究流程图,参照岗位评价要素库,运用内容分析法分析出基于战略贡献的岗位评价通用因素、等级、权重和等级赋值.
