基于SFA方法的碳排放效率 区域差异化与协调机制研究

本文主要采用SFA模型,将对碳排放效率有影响的七个变量加入模型,测算出1996-2011年的碳排放效率值。然后从时间和空间的角度分析了碳排放效率的变化趋势。研究表明,碳排放效率在整体上处于上升阶段,在地区上存在趋异的现象,即碳排放效率随着时间的发展表现出更大的地区差异性。因此,我们有必要建立系统的碳排放协调机制,保证碳交易市场有效运行。     

政府补贴、技术来源与创新绩效——基于重庆大中型工业企业的实证研究

文章以重庆大中型工业企业2000-2011年数据为样本,实证研究了细分技术源和政府补贴的创新绩效影响。结果表明:内部RD、技术改造和国内技术购买均可提升创新绩效,其中技术改造的创新绩效正影响最大;国外技术引进对创新绩效的直接影响显著为负,但国外技术引进与技术改造和国内技术购买存在显著的正向互动关系,说明国外技术引进需与技术改造和国内技术购买结合才能提升创新绩效;政府补贴可刺激企业扩大内部RD和技术改造而提升创新绩效,但难以影响企业国内外技术引进的决策。因此,技术改造对提升创新绩效最有效。

科技金融的保障政策分析——基于广州创新城市视角

在当今社会中,科技和金融是经济发展的两大动力,科技和金融的有效结合对于广州创新城市的建设有着重要的意义。文章结合科技金融的理论,根据广州创新城市发展现状,分析广州市科技金融发展存在的问题,并对此提出相应对策建议。在此基础上认为广州创新城市能够实现跨越式发展的关键在于:广州重视科技与金融结合,有效缓解了经济发展和科技创新中的技术与资金的矛盾,从而不断提高产业技术水平和国际竞争力。     

经济增长的技术效率及其影响因素研究——以四川省为例

运用2000—2010年数据,基于对数型柯布—道格拉斯生产函数的随机前沿模型,对四川省区域经济增长效率及其影响因素进行研究。结果表明,四川省经济增长主要靠劳动力驱动,平均技术效率水平较低,经济处于规模报酬递减状态,且其区域差异有扩大的趋势。而基础设施建设和科研投入对经济增长效率具有促进作用,金融机构的贷款业务和政府财政支出对效率的提高具有抑制作用。     

Environmental regulation and U.S. states' technical inefficiency

Using data on 48 states from 1982–1994, we estimate the impact of environmental regulation on technical inefficiency of U.S. states' manufacturing sector. The result indicates that environmental stringency has significant and positive impacts on U.S. states' technical inefficiency.     

Influence of technological support,skills and competencies,and learning on corporate entrepreneurship in European technology firms

In the today′s changing environment, firms are hardly competing with each other to achieve a competitive advantage that can differentiate them from others and improve their organizational performance. In this sense, it is crucial to develop corporate entrepreneurship and promote strategic variables that foster it.The aim of this paper is to highlight the importance of different technological variables (top management support to technology, technological skills and technological distinctive competencies) and organizational learning on corporate entrepreneurship, and thus analyze the influence of corporate entrepreneurship on organizational performance in the context of technology firms.A sample of 160 European technology firms was selected from the database Amadeus in 2009 with CEOs as our main informants. The hypotheses studied are empirically confirmed by using a hierarchical regression model.     

基于关联规则与信息熵的技术融合趋势研究

根据从德温特专利数据库中检索的专利数据,运用Apriori关联规则算法得到关于技术融合趋势的关联规则,然后通过基于差异思想的兴趣度模型验证规则的有效性,并在关联规则基础上利用信息熵评估企业核心技术领域分布及变化情况。最后,以安川电机和发那科公司为例进行实证分析。研究结果显示,基于差异思想的兴趣度模型弥补了关联规则因阈值设置主观性较强而导致部分规则无效的问题。     

Analysing wage differentials when workers maximize the return to human capital investment

The analysis of the determinants of differences in wages across workers has traditionally relied on the estimation of average earnings functions. In this article, we propose a new theoretical model where it is the workers who decide the amount they wish to invest in human capital, taking into account the costs of acquiring those skills, for the purpose of maximizing earnings. In this model, both human capital and marginal productivity are likely to be influenced by the individual’s (unobserved) characteristics such as ability or motivation, potentially giving rise to endogeneity problems. In this context, the empirical implementation of our theoretical model allows us, under certain assumptions, to obtain consistent estimates even under the assumption of endogeneity. We present an empirical application to the education sector using data from the Spanish Structure of Earnings Survey 2010. Our results show that females and workers in the private education sector face more difficulties in achieving their maximum potential wage.     

绿色低碳视角下技术创新影响因素研究

低碳技术创新是现阶段我国技术创新发展的重要任务,识别绿色低碳视角下技术创新影响因素对于促进我国绿色低碳技术的创新发展具有重要意义。通过扎根质化研究,综合提出了低碳技术创新绩效影响因素指标体系,然后基于投影寻踪法和多因变量对多自变量的偏最小二乘回归分析,得出低碳技术创新绩效影响因素回归模型。研究结果表明：现阶段我国低碳技术创新的能源消耗与环境污染较为严重;研发人员对于低碳技术创新产出影响较大;环境治理对低碳技术创新具有正向影响但不十分显著。
