福建省农业全要素生产率变动原因的实证分析

本文利用Malmquist指数方法,测算了1990—2007年福建省的农业技术进步率、技术效率增长率以及全要素生产率增长率;然后,利用协整检验和脉冲响应函数动态模拟福建省对外开放(对外开放度)对福建省农业技术进步变化率、技术效率变化率的影响,以及对外开放和两者的协整关系,进而说明福建省对外开放对其农业全要素生产率变动的作用。结果表明:20世纪90年代以来,福建省对外开放与其农业技术进步、技术效率变化和全要素生产率增长具有长期稳定均衡关系;福建省对外经济开放对福建省农业技术效率具有促进作用,但对农业技术进步具有"挤出效应"。     

基于发展水平和协调度的乡村振兴格局与分区研究——以江苏省为例

目的 乡村振兴战略是国家破解“三农”问题的系统部署,是激发乡村发展活力、实现农业现代化的必然要求。构建乡村振兴评价指标体系,对乡村振兴状况进行评价,是保证乡村振兴战略顺利推进的重要前提,也是当前研究热点,可为发达地区乡村振兴评价和针对性措施的制定提供参考依据,丰富乡村振兴的理论基础与研究思路。理论上可为衡量乡村振兴发展状况和制定区域发展政策提供参考,实践中可为江苏省乡村振兴实现进一步的突破提供科学指导。方法 文章以经济发达的江苏省为例,基于“指标体系—空间格局—空间分类”的研究主线,从产业兴旺、生态宜居、乡风文明、治理有效、生活富裕5个领域建立指标体系,借助熵值法、空间自相关、协调度模型对乡村发展水平和协调度进行评价,并开展乡村振兴的格局解析与分区研究。结果 江苏省乡村发展水平与地区经济社会发展水平呈明显正相关,表现为 “苏南最高、苏中居中、苏北最低”的空间格局;江苏省乡村振兴协调度存在明显差异,呈现“中部最高、南部居中、北部最低”的分布特征;综合发展水平与协调度,将研究区乡村发展分为重点突破型、全面推进型、协调发展型、优化提升型。结论 结合江苏省实际情况、现有研究成果探索了乡村振兴的发展方向,并针对不同类型地区提出相应的振兴策略。     

职业成长对员工建言行为的影响

基于员工利益视角,整合社会交换理论与关系人口学理论,并探索性地引入员工与主管前摄性人格匹配,可深入研究职业成长对员工建言行为的作用机理。运用多元线性回归分析多个组织的335份员工-主管配对样本数据,结果表明：职业成长对员工建言行为具有正向影响,员工对组织的责任感知在职业成长与建言行为间起到中介作用,员工-主管前摄性人格匹配不仅正向调节职业成长对建言行为的作用,而且正向调节责任感知对建言行为的作用。     

Strategic R&D investment,competitive toughness and growth

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market.     

浅议慈善与社会保障

社会保障和慈善的目的都是减轻人类灾难,促进社会福利,改善生活质量,慈善也是属于社会保障体系的一部分。但慈善属于道德层次,而社会保障属于法律层次。当前发展慈善事业对于完善社会保障体系,构建和谐社会,具;哿重要意义。     

Corporate Default Prediction Model Averaging: A Normative Linear Pooling Approach

Focusing on credit risk modelling, this paper introduces a novel approach for ensemble modelling based on a normative linear pooling. Models are first classified as dominant and competitive, and the pooling is run using the competitive models only. Numerical experiments based on parametric (logit, Bayesian model averaging) and nonparametric (classification tree, random forest, bagging, boosting) model comparison shows that the proposed ensemble performs better than alternative approaches, in particular when different modelling cultures are mixed together (logit and classification tree).

决策模型在职业生涯与发展决策过程中的应用

大学生是重要的人力资源,其就业是关系到个人前途和全社会发展稳定的大事。我们应从高校入手关注大学生的职业生涯发展,指导学生如何利用决策模型来规划自己的职业,这对大学生而言具有重要的现实意义。     

我国区域社会保障与商业保险协调度研究

本文构建了社会保障与商业保险协调度模型,定量研究了社会保障与商业保险的关系,并对模型进行了改进。结果显示:2005年~2010年我国绝大多数省份的协调等级都处于勉强协调和濒临失调的过渡区间,只有北京、山西、辽宁、上海和重庆在最近几年基本达到了初级协调,并且大部分省市的滞后类型为商业保险滞后型。基于上述分析,本文提出了促进社会保障与商业保险进一步协调发展的相关建议。     

Corporate Social Performance,Competitive Advantage,Earnings Persistence and Firm Value

In this paper, using a generalised valuation framework inspired by Ohlson, we show that corporate social performance (CSP) is value relevant and that, in particular, it appears to be associated with a higher coefficient on earnings. This could be attributable to either a lower cost of equity for these firms, or greater earnings persistence. We show that, once industry membership is controlled for, any cost of capital effect is minimal. Regression tests based on realised earnings confirm that the valuation effect is attributable mainly to greater earnings persistence in firms with higher levels of CSP. These outcomes are consistent with higher CSP conferring a competitive advantage on firms.     

Use of social media by university accounting students and its impact on learning outcomes

The proliferation in the use of social media, such as Facebook and Twitter, among university students is well documented. With many universities providing student resources in formats suitable for iPad, laptop, and mobile phone use, the use of social media for university activities has become easier. This study explores the use of social media by university accounting degree students to support their academic activities in an informal setting. It explores the impact these media have on learning outcomes. Our findings suggest that university accounting degree students use social media for a number of academic-related purposes. Students establish and maintain fluid mentor/mentee relationships around academic activities related interactions through the social media. We have found that the use of Social Media is significantly associated with students’ grades.
