长江经济带绿色金融与产业绿色发展耦合协调研究

在梳理绿色金融与产业绿色发展的耦合机理的基础上,构建耦合协调度模型,利用长江经济带九省二市2012—2017年数据,分析长江经济带各省市绿色金融与产业绿色发展耦合协调关系。研究发现：第一,长江经济带绿色金融促进产业绿色发展,产业绿色发展反哺绿色金融成效显著,二者已达到良性共振耦合,耦合协调度不断提高,发展阶段经历了勉强协调、初级协调、中级阶段到良好协调,并向着优质协调靠拢;第二,上游地区产业绿色发展已形成了区域内合作机制,产业绿色发展迅速,绿色金融与产业绿色发展耦合协调度自2012年以来上升最快;第三,九省二市绿色金融与产业绿色发展的基础和侧重点不同,二者耦合协调度呈现一定差异,但都达到了良好协调阶段。针对长江经济带绿色金融和产业绿色发展二者耦合协调度现状,提出了相应的对策建议。

曲线箱梁桥实用设计方法的研究

曲线箱梁桥目前还缺乏比较实用的设计方法．本文对曲线箱梁桥的现有设计方法作了研究，并推荐一种实用设计方法：采用空间梁单元，每个节点取六个自由度；等效梁格的模拟考虑了横向梁格附近有无横隔梁的情况．结果证明，这是一种简便、较精确的设计方法．     

Infill asymptotics for adaptive kernel estimators of spatial intensity

We apply the Abramson principle to define adaptive kernel estimators for the intensity function of a spatial point process. We derive asymptotic expansions for the bias and variance under the regime that n independent copies of a simple point process in Euclidean space are superposed. The method is illustrated by means of a simple example and applied to tornado data.     

基于同城化视角的人口空间动态与区域经济发展耦合关联机理研究

人口空间动态与区域经济发展的耦合关系是同城化区域间共同面对的重要课题。本文在解构人口空间动态维度主体的基础上,将人口空间动态的诉求机制与动因机理架构于更低交易费用的利益诉求之上,解析人口空间动态的模式选择,深入探讨人口空间动态与区域经济发展的耦合关联性。在此基础上,提出引导人口流动与合理分布的策略。研究成果将有助于更好地理解同城化态势下人口空间演变的动因机理,为同城区域的经济发展、城市规划、文化交融等方面的科学设计提供重要参考。     

Job quality,industrial relations and the crisis in Europe

This paper reports results from recent Eurofound research on the impact of the crisis on industrial relations and working conditions in Europe, based on the output of Eurofound's European Working Conditions Observatory and European Industrial Relations Observatory and data from the European Working Conditions Survey. Overall, the crisis – even if it is sometimes difficult to separate the effect of the crisis from megatrends in working conditions and industrial relations – seems to have had an impact on both domains. With reference to industrial relations, the impact of the crisis has influenced actors, processes, and outcomes. Regarding working conditions, the results appear to be in line with the literature on the topic, which relates the crisis to an increase in job insecurity, a decrease in work intensity, in working hours, and in anti-social working time arrangements, and a general improvement in terms of health risks and related outcomes.     

Did small and medium enterprises maintain better jobs during the early years of the recession? Job quality multidimensional evidence from Spain

While the literature has indeed confirmed a general tendency linking small and medium enterprises (SMEs) to a dynamic of greater job creation, there is little available evidence on what has happened to job quality since the financial crisis. Through a representative sample of 5311 employees in 2008 (first year of job destruction) and 4925 employees in 2010 (last year for which data were available), and using a two-stage structural equation model, this article empirically analyses the multidimensional determinants of job quality, by enterprise-size class, in Spain. The research has revealed three main results. First, job quality in Spain improved in all enterprises, regardless of their size, during the early years of the recession. Second, the greatest improvements were found in SMEs. Although job quality was already better in SMEs than in large enterprises in 2008, the differences between them subsequently widened. Third, this accelerated divergence was explained by the following dimensions: working conditions, work intensity, health and safety at work, and work–life balance. These dimensions were much more positive in SMEs. Employment-related public policy should therefore focus more specifically on SMEs. There are two reasons for this. First, despite the recession, SMEs have shown themselves to be key factors in the explanation of job quality. Second, by making changes to their value generation model, they could continue to drive the creation of better quality jobs.     

Decomposition of Variance for Spatial Cox Processes

Abstract. Spatial Cox point processes is a natural framework for quantifying the various sources of variation governing the spatial distribution of rain forest trees. We introduce a general criterion for variance decomposition for spatial Cox processes and apply it to specific Cox process models with additive or log linear random intensity functions. We moreover consider a new and flexible class of pair correlation function models given in terms of normal variance mixture covariance functions. The proposed methodology is applied to point pattern data sets of locations of tropical rain forest trees.     

动态环境下联盟竞合、治理机制与创新绩效的关系研究

本文从竞合视角审视联盟组合,结合动态关系观探讨有效的联盟治理机制,揭示了联盟组合中竞合关系(横向竞合、纵向竞合)、治理机制(契约治理、关系治理)和创新绩效之间的关系,并考察了动态环境特征(技术波动、竞争强度)的二次调节作用。在不同的竞合关系中,由于合作和竞争的强度不同,契约治理与关系治理机制的作用也存在差异,同时,治理机制与创新绩效之间的关系也受到两种不同环境动态性特征的影响。研究结果显示,在纵向竞合中,运用关系治理比运用契约治理能更好地提升创新绩效,技术波动正向调节契约治理、关系治理与创新绩效间的关系。在横向竞合中,运用契约治理比运用关系治理有效,竞争强度加强了契约治理对创新绩效的影响,即关系治理在波动的环境中更有效,契约治理在竞争的环境中更有效。本文为企业开展研发联盟组合管理提供了新的视角和管理对策。
