基于Logistic模型的东北地区粮食生产能力影响因素研究——以宾县为例

[目的]粮食生产能力关系到粮食供给和国家粮食安全,如何提高粮食生产能力是我国亟待解决的问题。文章以宾县为例,通过一定的方法探索粮食生产能力的影响机制,最终提出提高粮食生产能力的合理建议。[方法]利用农户调查数据,借助Logistic模型探讨自然因素和社会经济因素对粮食生产能力的影响特点。[结果](1)品种技术推广、作物收益对粮食生产能力的影响效应在1%水平上达到显著;(2)生育期变化、土地质量、旱灾、耕作方式对粮食生产能力的影响效应在5%水平上达到显著;(3)温度、降水、冷害及农业生产资料投入对粮食生产能力的影响效应在10%水平上达到显著;(4)温度与降水是否集中在生育期内、出售情况、农业引导政策对粮食生产能力的影响不显著。[结论]针对研究结果,该文提出,可从预防低温冷害、健全水利设施、完善耕地保护制度及加强农业基础设施建设等方面提高粮食生产能力。     

Industry risk transmission channels and the spillover effects of specific determinants in China’s stock market: A spatial econometrics approach

This paper uses a spatial econometrics approach to study the industry risks in China’s stock market. We comprehensively consider the real linkage and information risk transmission channels and analyze the risk spillovers of specific determinants. Our empirical results show the following: 1) The real linkage channel and information channel are both effective transmission channels for driving spillover effects, and the information channel is of the utmost importance. 2) The spillover effects of specific determinants exist and are persistent. The superposition of spillover effects may lead to extreme risk. 3) The transmission channels and spillover effects are asymmetric in different regimes.     

数字化、专业化模式转型与企业生存风险

数字化、专业化转型是企业实现高质量发展的关键。并表近年上市公司数据,采用半参数Cox估计方法构建企业生存风险函数,分解企业生产经营的内部控制与外部环境因素。研究发现,专业化转型确实能延长企业的生存周期,而数字化转型却产生了背离预期现实的结果,即数字化转型一定程度上增加了企业的生存风险。因而,企业应注重内部人员管控能力与企业经营能力,地方政府应提升并优化营商环境,进而发挥专业化与数字化转型的市场潜力。     

A truly global crisis? Evidence from contagion dependence across international REIT markets

This study examines the global nature of the recent crisis under bivariate Markov-switching models for pre- and post-crisis periods using the breakpoint of August 9, 2007. It quantifies international synchronization of boom-bust regime switches to investigate contagion-type dynamic comovements of Real Estate Investment Trusts (REITs). Global REIT markets display persistent bust regimes from September 2008 to May 2009, whereas the regime-switching patterns are not significant in the pre-crisis period. The results provide new evidence for global REIT contagion phenomena and suggest greater difficulties in diversifying risks across global REIT markets during the post-crisis period.     

上海小城镇社保模式探索及其启示

上海小城镇社保“24％＋X”的基本模式具有“低平台、有弹性、广覆盖”三大特点，充分考虑了当前上海郊区的经济发展水平和郊区人口对于社会保障的现实需求，较好地体现了社会保障多层次以及同当前经济发展水平相适应的原则，在实践中取得了较好的效果。本文通过对上海小城镇社保的分析，试图为我国农村社会保障制度的发展提供新的思路。     

行业标准化对中国进出口贸易的影响研究

以1993~2008年中国钢铁、煤炭、服装、食品加工、家电、机械制造六个行业的行业标准数目为基础,利用面板数据变截据模型分析行业标准化对进出口贸易的总体影响,通过面板数据变系数模型分析行业标准化对其进出口贸易额的影响。结果表明,我国的行业标准化对进出口贸易均存在正面影响,行业标准对钢铁、煤炭行业的进出口及对家电的出口均产生负面影响,对服装、食品加工、机械制造及家电的出口均产生正面影响。     

基于层次分析法的企业循环经济发展模式选择模型研究

首先以企业产权边界、企业间联系两个维度为依据,归纳了企业发展循环经济的五种模式。随后运用层次分析法,在充分考虑了循环经济本身特有的稀缺性、外部性、稳定性、收益性等经济学特性后,提出企业选择循环经济发展模式决策模型。最后通过模型计算分析,指出企业集团循环经济发展模式应该是未来企业推进循环经济理论研究和实践重点。     

企业信息化项目管理对项目成功的影响研究

在企业信息化项目中,项目管理是企业深化改革和提高信息化效益的重要途径。但是项目管理究竟在项目建设中发挥了多大作用,对项目成功起到了怎样的影响,这一直以来都是一个模糊的概念。文章通过问卷调查和结构方程模型具体衡量项目管理对项目成功的影响程度。     

Disentangling the drivers of renewable energy investments: The role of behavioral factors

The scope of this study is to investigate the main determinants of renewable energy investments in Greece. For this reason, we build an appropriate framework to infer the decision‐making process in the renewable energy sources (RES). The main drivers are then categorized under two groups as economic, and behavioral ones. In the next stage, we rely on binomial (logit and probit) and quantile regression analysis to estimate the impact of these factors on investment decisions towards RES. Our findings indicate that investors who gain better access to knowledge and exhibit a more positive attitude towards the contribution of artificial intelligence (AI) on the RES industry have a higher share of renewables in their portfolio. We argue that these investors are willing to invest a higher amount in the RES industry today. At the same time, quantile regression models illustrate that this relationship is nonmonotonic (i.e., inverted U shaped curve), arguing that positive attitudes towards the contribution of behavioral factors on RES are not adequate to encourage investments after crossing a certain point (threshold). Based on the empirical findings, we argue that the message to policymakers and government officials is to promote a faster penetration of low carbon technologies to achieve sustainable economic and social growth.
