Do jobs follow people or people follow jobs? A meta-analysis of Carlino–Mills studies. Spatial Economic Analysis. This study examines the classic question as to whether ‘jobs follow people’ or ‘people follow jobs’ by performing a meta-analysis of 321 results from 64 Carlino–Mills studies. It is found that the results are highly divergent, but that more results point towards ‘jobs following people’ than towards ‘people following jobs’. When it comes to the reasons for the variation in results, we find that the results are mostly shaped by the geographical location, spatial resolution, and population and employment characteristics present in the data, as well as by the model’s specification, its functional form and the spatial weight matrix specification. 相似文献

This study illustrates the fundamental importance of a political understanding in order to improve HRM in both public and private organizations. It complements studies that have found a statistical relationship between public staff management and economic growth by presenting a case study of Morocco, using the strategic human resource management (SHRM) model as a framework. There are several reasons why HRM in the Moroccan civil service has stagnated, notably unfamiliarity with HRM models and the French administrative heritage. But the fundamental reason is Morocco's political system, where real power resides in the Palace, and where political actors are reluctant to take bold initiatives. Thus a focus on the management level is currently misplaced, and fundamental political action harnessing the authority of the Palace without disempowering other political actors is needed. The study implies that a political analysis is sometimes a prerequisite for improving HRM in both public and private organizations. 相似文献

[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。 相似文献

The credit risk contagion of Internet peer-to-peer (P2P) lending platforms is an important part of Internet financial risk management and supervision. This study analyzes the contagion path of credit risk in Internet P2P lending. Based on complex network theory and the theory of infectious disease dynamics, the characteristics of Internet P2P lending development are combined to construct a SEIR model of credit risk transmission among Internet P2P lending platforms with time lag, and the robustness of the model is analyzed and proven. The influence of platform correlations, the susceptible immune rate, the platform elimination rate, contagion latency, the saturation coefficient, and the susceptibility input rate on credit risk contagion behavior among Internet P2P lending platforms is analyzed, using the equilibrium point and threshold value. The impact of each variable is analyzed by simulation. Corresponding countermeasures and suggestions are proposed to prevent and control credit risk contagion among these platforms. 相似文献

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. 相似文献

In this paper we propose a subsampling estimator for the distribution of statistics diverging at either known or unknown rates when the underlying time series is strictly stationary and strong mixing. Based on our results we provide a detailed discussion of how to estimate extreme order statistics with dependent data and present two applications to assessing financial market risk. Our method performs well in estimating Value at Risk and provides a superior alternative to Hill's estimator in operationalizing Safety First portfolio selection. 相似文献

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。 相似文献

基于VAR模型下粮食价格、农业生产成本与农民收入的实证研究 总被引:2,自引:0,他引:2
通过脉冲响应函数得出农业生产资料价格与粮食价格,同时上涨,部分或者完全抵消了粮食价格上涨以及国家试图提高农民收入、调节收入分配而出台的各项优惠政策对农民收入的增加效应。Granger因果检验说明粮食价格、农民收入分别是农业生产成本的Granger原因。为此,政府必须将农业生产资料价格的上涨幅度控制在合理区间,改善农村物流现状,规范农资市场的经营等。 相似文献

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. 相似文献
