基于状态空间模型的政产学研资协同创新四螺旋影响因素实证研究

在三螺旋理论框架下,搭建政府、产业、大学、研究机构和资本部门四螺旋模型,运用文献归纳法选取多元主体协同创新6类影响因素,以主体间协同程度测度结果为因变量基础,利用状态空间模型动态分析这些因素影响方向、大小和趋势。实证结果表明,中国经济因素表现为促进作用持续提升;中国技术市场规模和创新产业规模表现为先抑制后促进,且促进作用不断提升;中国产品市场需求和创新投入表现为抑制作用持续提升;中国创新产出在时间上表现为促进作用先提升后下降并最终稳定的状态。最后,提出不同政策建议,以促进中国政产学研资协同创新体系后续发展。     

基于数据包络(DEA)分析的京津冀地区环境绩效评估研究

提高资源环境绩效是区域生态环境治理的核心与关键。在构建环境绩效评估指标体系的基础上,运用数据包络分析模型（DEA）测度并分析2005-2015年京津冀地区静态环境绩效水平。利用Malmquist指数动态分析法将环境绩效分解为技术效率变化指数和技术进步指数,并探讨分解指标对环境绩效的相对贡献。结果显示：京津冀地区环境治理投入与产出水平均呈现逐年上升趋势;北京和天津的总体环境绩效水平要远高于河北,2005-2011年京津冀地区的环境绩效水平排序为北京、天津、河北,2012-2015年京津冀地区的环境绩效水平排序为天津、北京、河北（2013年除外）。河北省环境绩效水平较低的主要制约因素是技术进步缓慢与全要素生产率偏低。Malmquist指数呈现出一定的波性,这主要是由技术变化指标波动所致。最后,就如何提升京津冀地区环境绩效水平,提出相关对策建议。     

Portfolio efficiency analysis with SFA: the case of PSI-20 companies

This study aimed to assess the technical efficiency (TE) of individual companies and their respective sectors that are traded on the Portuguese stock market. We accomplished this by combining the internal input variables (e.g., ‘market value and return’) with exogenous variables (e.g., ‘interest income’, ‘depreciation’, ‘cost of goods’, ‘employees’ and ‘net sales’) into a Stochastic Frontier Analysis (SFA) model. The TE of the PSI-20 (Portuguese Stock Index) was estimated using factors that affect efficiency variability. The main advantage of using the SFA approach is its potential to discriminate between measurement error and systematic inefficiencies in the estimation process. The results demonstrated that TE is higher for enterprises in the industrial, construction and distribution sectors, whereas the commercial banking sector has the lowest TE scores. The ‘employees’ and ‘depreciation’ are the variables which most contribute to stock market inefficiency.     

商业集群的发展历史及产业集群打造

随着全球一体化进程的加快和越来越激烈的全球竞争,创建具有竞争力的产业集群是许多政府和企业的共同心愿。但产业集群作为商业集群的最高历史阶段,其打造并不是一挥而蹴的事情。商业集群的形成和转型具有客观规律性,从低级到高级商业集群分为：地理集群、市场集群、网络集群、创新集群和产业集群。商业集群每个发展阶段具有不同的特点和不同的形成条件,从低级到高级的转化与升级具有内在驱动机制,必须掌握这种内在驱动机制并努力满足相应条件,才有可能使商业集群顺利地形成、转型或升级,否则,欲速则不达。     

中国知识产权政策的演变(1985-2009)——一个量化的视角

随着我国对自主创新能力的重视程度不断提高,政府先后出台了多项知识产权政策,这对我国加强知识产权保护以及促进技术创新起到了一定的作用,但是也存在着许多问题。通过建立知识产权政策的量化标准,对1985年以来我国颁布的知识产权政策进行分析,描绘了我国知识产权政策的演变规律。

基于效益视角的创新链合作机制研究

创新链是描述一项科技成果从创意的产生到商业化生产销售整个过程的链状结构,主要揭示知识、技术在整个过程中的流动、转化和增值效应,也反映各创新主体在整个过程中的衔接、合作和价值传递关系。在提出创新链概念,分析创新链特征的基础上,重点论述了合作机制是创新链提高创新效率、减少创新失败的关键运行机制,并构建了创新链上研发主体、生产主体和销售主体之间的合作机制,最后用博弈论分析证明了各主体进行全面合作,才是获取创新收益最大化的最优选择策略。     

Efficiency in the provision of social care for older people. A three-stage Data Envelopment Analysis using self-reported quality of life

Using a three-stage data envelopment analysis approach, this paper explores efficiency in the provision of social care for older people in 148 English Councils in 2009/10. Departing from D'Amico and Fernández (2012) [31] our measure of efficiency is inscribed within the production of welfare framework and based on self-reported quality of life of recipients of the services. Our results indicate a high level of efficiency, but once we control for the effects of a number of environmental variables, we found that more stringent eligibility criteria and higher assessment costs are negatively associated with the efficiency in the provision of social services.     

An alternative approach to the monitoring of technological diffusion via foreign direct investment: evidence from the Greek manufacturing sector

The existing studies of foreign direct investment and the corresponding technological diffusion process that they generate, focus either on specific parameters of the production process in isolation, or they combine certain parameters to construct indices that are not consistent across studies. The present analysis proposes an alternative approach that captures the entire production process and multinational firms are viewed as the platform that transfers more advanced technologies to the host countries. As multinational firms are able to utilise more efficiently the available production process, an efficiency gap ensues between the domestically owned firms of a country and the multinational firms that operate in it. We capture and provide a measure and a monitoring mechanism of the technological diffusion process via foreign direct investment through the evolution of the efficiency gap between the two groups of firms whilst controlling for other variables that might contribute to such a gap. We apply our approach to the manufacturing sector of the Greek economy that experiences a consistent presence of foreign direct investment inflows over the time period 2001–2007.
