小型工业企业运行效率的影响评价研究——以公司注册资本自治为背景

从2014年3月起我国公司注册资本方式改为认缴出资,且注册程序也大大简化了,这意味着我国正逐步放开管制,促使公司资本更有效地参与市场经济。资本出资、验资方式的改变,旨在提高市场经济的运行效率,所以本文选取小型工业企业作为研究对象,因为其对注册资本登记制度的改革最为敏感及受益,通过对其前后运行效率的评价研究来检验市场经济的运行效率和公司注册资本制改革的效果。得出结论：改革前后企业运行效率的主要影响因素是相同的,只是顺序有点变动;山东政策落地效果最好;江苏、广东充分调动社会资本力量的参与;浙江狠抓市场环境优化、扩大企业出口;河南高创业热情带动就业。表明公司注册资本制的改革是有效的,能够改善绝大多数省份企业运行效率。但同时也发现存在资本结构不合理、市场环境不好、市场化水平低等问题,就此提出了相关政策建议。     

基于云重心Shapley值的供应链融资联盟收益分配研究

针对Shapley值法在供应链融资联盟收益分配过程中分配因素考虑不全以及各分配因素随机性和模糊性强的缺点,本文利用云重心法修正Shapley值的收益分配。根据供应链融资联盟收益分配的主要影响因素,在传统的Shapley值法的基础上引入了风险系数、投入成本、努力程度以及信息对称水平4个分配修正因子,弥补了影响因素的缺失,并利用云重心法计算各联盟企业的收益修正值,云重心法能够解决定性指标和定量指标之间的模糊性转换,极大克服了Shapley值法自身的局限性。算例对比结果发现,改进的Shapley值法能更加合理的分配收益,有利于维持供应链融资联盟的稳定。     

我国科技-经济-生态系统的综合发展水平及其协调度评价——基于灰关联投影寻踪协调度组合评价模型

科技创新、经济发展与生态环境建设作为国家治理体系的重要组成部分,对于我国国民经济和社会发展具有明显的推动作用。本文参考现有文献中科技创新、经济发展与生态环境建设3个维度的相关指标,构建科技-经济-生态系统协调度评价指标体系。并采用灰关联分析法、投影寻踪法和协调度模型,综合评价我国不同时期的科技-经济-生态系统的综合发展水平及其协调度。研究结果表明,2000～2015年,我国科技-经济-生态系统的综合发展水平处于快速增长阶段,年均增长率为6.22%,其中,科技创新水平、经济发展水平、生态环境建设水平的年均增长率分别为5.95%、5.35%、6.43%。同时,我国科技-经济-生态系统的协调度达到0.992。其中,“十五”～“十二五”时期,我国科技-经济-生态系统的协调度持续提升,分别达到0.8465、0.8466、0.9152。总体来看,在经济发展新常态下,我国政府通过加快转变经济发展方式和社会发展方式,同步提高科技创新水平、经济发展水平、生态环境建设水平,有利于进一步提升科技-经济-生态系统的综合发展水平及其协调度。     

环境约束下中国工业企业创新效率评价及影响因素研究

本文应用SBM模型的改进DEA模型以及DEA-Tobit法对中国2006～2015年环境约束下工业企业技术创新效率及其影响因素进行实证分析,研究结果表明,非期望产出对企业效率评价结果有较大影响,北部沿海综合经济区的环境效率值最高;西北综合经济区、长江中游综合经济区、黄河中游综合经济区、东北综合经济区环境效率值相对较差。政府支持力度、企业规模与环境约束下的工业企业技术创新效率呈正相关关系,企业聚集度与其呈负相关关系,而企业技术水平与从业人员素质对其影响较小。     

基于生态位适宜度的区域创新生态系统与创新效率研究

由于区域内创新资源的有限性,区域创新生态系统中创新主体生态位之间的重叠程度对创新效率的影响愈发的显著,基于此本文运用生态位适宜度评价模型对我国30个省市 2011~2015 年的创新生态系统适宜度水平进行了测度,并分别与运用超效率数据包络分析法所测得的区域知识创新效率和产品创新效率进行了面板数据的回归分析。结果显示,区域创新生态系统的生态位适宜度对两个阶段的创新效率均具有正向的相关关系,但这种影响只具有短期的时间维度,并不存在两年及以上的相互作用。区域创新生态系统的对外开放会对产品创新阶段的创新效率产生负面影响,同时会促进知识创新阶段创新效率的提高。最后,在协调系统内部各生态位之间的发展关系时,应注重区域内经济发展水平对两个阶段创新效率的促进作用。     

Estimating Value Creation from Revealed Preferences: Application to Value‐based Strategies

Research summary : We develop and apply a new set of empirical tools consistent with the tenets of value‐based business strategies, leveraging the principle that “no good deal comes undone” and the methods of revealed preferences, to empirically estimate drivers of value creation. We demonstrate how to use these tools in an analysis of value creation in buyer–supplier relationships in the UK corporate legal market. We show that our approach can uncover evidence of subtle mechanisms that traditional methods cannot easily distinguish from each other. Furthermore, we show how the estimates can be used as parameters of biform games for out‐of‐sample analyses of strategic decisions. With readily available data on relationships between firms, this approach can be applied to many other contexts of interest to strategy researchers. Managerial summary : Managers need to understand the drivers of value creation for customers in order to make competitive positioning decisions and understand when they can capture value under competition. However, estimates of the relative importance of each driver are typically difficult to obtain. In this article, we help remedy this problem by demonstrating a novel method that obtains estimates of the contribution of various drivers of value creation from commonly available data of buyer–supplier relationships. These estimates can then be used to inform the strategy‐making process. Copyright © 2017 John Wiley & Sons, Ltd.     

Blocked But Not Tackled: Who Founds New Firms When Rivals Dissolve?

Research summary: This article examines the role of competitive shocks in creating opportunities for new firm foundings. I argue that the sudden dissolution of rival firms may release resources that create opportunities for firm formation, particularly among employees facing impediments to capturing value in their current organizations. Analyzing microdata from the legal services industry, I use unexpected deaths of solo‐practicing attorneys as quasi‐exogenous sources of rival dissolution. Results indicate that these shocks increase the odds of founding by about 30%, with stronger effects among attorneys with weaker social connections or higher competition for promotion. The article thus highlights the role that founders play in reallocating dissolved rivals' resources while demonstrating that founding may be an important outlet for “blocked” employees to capture value from opportunities. Managerial summary: This article finds that the shutdown and dissolution of a rival organization may spur employees to found new firms. As a consequence, managers may find it valuable to pay attention to employees' turnover intentions following the dissolution of a rival. Findings suggest that employees who are having trouble advancing in the firm may be the most likely to found a new organization when a rival dissolves, so managers may want to focus retention efforts on these individuals. To the extent that managers wish to capture customers, employees, and other resources that were formerly attached to a dissolved rival, managers may wish to be aware that they could be in competition with their own employees for these resources and opportunities.

The Benefit Function Approach to Modeling Price-Dependent Demand Systems: An Application of Duality Theory

In this article, we advocate more extensive use of the benefit function in specifying price-dependent or inverse demand models. We demonstrate how duality theory may be used to establish the interrelationships between the Marshallian (or Hicksian) inverse demands and Luenberger's adjusted price functions, allowing estimable inverse demands to be derived directly from a benefit function. We estimate two systems of inverse demands for Japanese quarterly fish consumption. Results indicate that the procedures and methods employed here appear promising, and may prove beneficial for quantity and welfare analysis when modeling systems of inverse demand functions.     

Municipal commonage policy and livestock owners: Findings from the Eastern Cape,South Africa

The new African National Congress government announced after 1994 that municipal commonage would be a pillar of their land reform programme. The Department of Land Affairs spearheaded this by acquiring new land to complement the existing ‘old’ commonages. The aim of old commonage was to supplement the income of poor urban residents through the subsistence user system whereas new commonage was intended as a ‘stepping stone’ for emergent farmers. We investigated the differences between old and new commonage farmers as well as how they perceived the Makana local municipality's capacity to manage the commonage. The results showed that local institutions were weak. Only 46% of the old commonage farmers were members of a local livestock association whereas 74% of the new commonage farmers were members. Most old commonage farmers (59%) were dissatisfied with local government's management of the commonage. In contrast, only 37% of the new commonage farmers were dissatisfied with the management of the commonage. There were no differences between old and new commonage farmers in terms of livestock owners’ characteristics and mean annual net direct-use value of livestock. There were also no differences in the age of the two types of commonage farmers. Furthermore, there was no association between the type of commonage and level of education. The mean annual net direct-use value of livestock on old commonage was R6308 compared with R9707 on new commonage. Although the income from livestock for new commonage farmers varied slightly from that of old commonage farmers, the annual productive output per farmer on old commonage was R473 ha⁻¹, three times higher than that of new commonage farmers which was R134 ha⁻¹. We suggest that new land policy legislation is needed in which poverty as well as the legal arrangements between all stakeholders is clearly defined. Furthermore, national departments need to be more involved with local municipalities to increase local management capacity.
