人力资本与企业绩效关系的实证分析

国内外对企业绩效的实证研究主要是研究财务指标与企业绩效的关系,缺少对非财务指标的实证研究特别是人力资本与企业绩效关系的实证研究。本文选取反映人力资本的指标和反映企业绩效的指标,随机选取上市公司的数据进行多元回归分析,结果发现,员工高学历比例和员工专门技术人员比例,与企业绩效存在显著关系。笔者建议,要明确企业绩效与人力资本的关系,重视人力资本的作用,同时要结合行业特点和竞争程度综合考虑企业绩效。     

基于PSR模型的区域高技术产业创新要素供给评价

区域高技术产业高质量发展需要创新要素有效供给。基于PSR（压力—状态—响应)模型构建高技术产业创新要素供给评价指标体系，采用全局熵法对我国创新要素有效供给现状进行评价，并度量创新要素供给协调度，从创新要素供给综合指数和子系统协调度两个方面评价创新要素有效供给水平。在此基础上将我国区域创新要素供给分为5个梯度，并运用障碍因素诊断模型，分析影响各梯度省域高技术产业创新要素有效供给实现的主要障碍因素。研究发现，影响有效供给的主要障碍层从2009年的压力层与状态层转变为2018年的响应层与状态层，高技术产业发展水平等成为主要障碍因素。各省域应依据自身要素供给主要障碍层和障碍因子，结合自身创新要素供给所处梯度，采取针对性措施，通过强链、补链、固链相结合，实现区域高技术产业创新要素有效供给。     

Diversity in foresight: Insights from the fostering of innovation ideas

Foresight activities have often provided support for objectives such as priority-setting, networking and consensual vision-building. In this paper, we draw upon complementary evolutionary perspectives and discuss these objectives from the viewpoint of diversity which may be vital in contexts characterized by technological discontinuities and high uncertainties. We also argue that although the scanning of weak signals has been widely advocated in such contexts, the solicitation of ideas for prospective innovations may provide more focused, action-oriented, and comparable reflections of future developments. For the analysis of such ideas, we develop a collaborative foresight method RPM Screening which consists of phases for the generation, revision, multi-criteria evaluation, and portfolio analysis of innovation ideas. We also report experiences from a pilot project where this method was employed to enhance the work of the Foresight Forum of the Ministry of Trade and Industry in Finland. Encouraging results from this project and other recent applications suggest that RPM Screening can be helpful in foresight processes and the development of shared research agendas.     

Making green discourses matter in policy-making: Learning from discursive power struggles within the policy area of car taxation

This paper is about stability and change in the policy-making discourse of a traditional neoclassical policy area, the area of car taxation. Stability is here related to the unquestioned continuation of a traditional neoclassical economics perspective in policy-making, whereas change is related to the introduction and impact of environmental concerns. The aim of the paper is to investigate, what makes green discourses matter in traditional policy-making. It is based on an in-depth study of policy-making processes related to car taxation in two environmental front-runner countries, Sweden and Denmark.Making green discourses matter in policy-making is an important contemporary environmental challenge. Therefore, as Tian Shi argues, we need more research into the institutional setting of the policy-making process. Ecological economics as a policy science has to have a broad understanding of the political economic nature of the policy process. Taking this standpoint as the point of departure, the paper seeks to uncover questions such as, what is the policy-making reality in which Swedish and Danish green discourses have to make a difference? How do existing neoclassical regimes react, when green actors attempt to influence policy-making from an environmental point of view? And to what extent can green discourses actually have an impact on the policy world within the area of car taxation?The paper concludes that the traditional neoclassical economic discourse is particularly robust and resistant against alternative green discourses. Stability rather than change is the dominating picture. This does not imply that environmental concerns will not be taken into account in the future. Rather it implies that only the changes, which keep up the existing order, or enhance the narrow power-related interests of the dominating actors, will materialise more or less easily. The rest is a power struggle in which timing, coalition-building, persistence and thorough knowledge about the field in question is of importance. In this struggle change agents will also benefit from the ability to rethink dominating ways of thinking and doing in an environmentally benign way. A rethinking that is based on environmental values while at the same time holding positive visions that are ‘compatible’ with the existing dominating discourse.     

城镇居民教育收益率的地区差异及其解释

利用中国社会科学院经济研究所"中国城乡居民收入分配"课题组1995年和2002年的家庭抽样调查数据,本文使用分层线性模型重新估计了1995年、2002年我国居民的教育收益率,得到了不同于OLS估计的结果:(1)我国城镇居民教育收益率的地区差异很大,差异主要来源于省内各城市之间,来源于省间的差别并不显著;(2)计算了省内城市劳动力市场化程度对当地教育收益率的边际影响,发现劳动力市场的发育确实有利于提高教育收益率,而且劳动力市场化程度的差异在一定程度上为各地教育收益率的差异提供了解释。     

外商投资与中国经济发展──产业和区域分析证据

本文将有关外商直接投资影响的分析 ,与中国经济的特定发展模式联系起来 ,从中得出两项分析结果。一是在产业发展层面 ,外商投资确实有助于改进资源配置效率 ,然而这种贡献却是以妨碍生产效率改进为代价的 ;二是在区域发展层面 ,以进口替代加资本深化为特征的“上海模式” ,在促进地区和全国经济发展方面 ,确实优于以出口导向加劳动密集为特征的“广东模式” ,只是前一模式本身存在着严重的可持续性问题     

基于主成分分析法的人类发展指数替代技术

在本文中,我们采用基于协方差的主成分分析法来分析1990年以来UNDP发布的中国人类发展数据,然后采用Spearman秩相关系数来分析获得的主成分与HDI之间的关系。研究表明,主成分分析法不仅能够有效地替代传统的人类发展指数编制方法,其形成的动态权重结构还可以有效地透视人类发展差距模式的历史演进过程,以及人类发展的各个方面(如预期寿命、知识教育和体面的生活等)在整体发展进程中的角色变化。对中国人类发展数据的分析结果也表明,尽管1990年以来中国各地区在经济、教育和健康方面均取得了重大进步,但三项发展之间存在着严重的不协调,地区发展差距也越来越多地体现为经济发展差距,这些反映了改革开放以来中国各级政府过分强调经济增长而带来的片面、不协调的人类发展。实现经济社会的协调发展,是时代的要求,也是当前我国各级政府面临的主要任务。而强调公共服务职能、推动地方政府的服务型转型,是消除不平衡发展的关键。

油井采出液处理效果分析及改进措施研究

通过对油站和污水站的化学成分分析，找出了电脱水器跳闸的原因：由于污水中的一些成分导致腐蚀，腐蚀产生的硫化铁和铁颗粒，随着油水混合液在管线中运移，在电脱水器上越积越厚，致使电脱水器上导电率增高，电脱水器跳闸。提出了改善注入水水质，减缓腐蚀的有利措施。     

跨国公司对我国汽车合资企业控制分析

跨国汽车公司以国际直接投资(FDI)方式建立合资企业是我国汽车产业利用外资的主要形式.在实际运行中,股权比例的安排并不等于实际控制权的分配,合资企业对合资双方相关资源依赖性的强弱决定了合资双方的实际控制权.跨国汽车公司借助技术垄断优势,通过双方合资时的约定或日后实际运作中的设计安排,以非股权约束的方式来实现对合资企业的实际控制.
