农业作为国民经济的基础,必须要有持续发展的能力,而这种持续发展必须有强有力的金融支持。我国农业发展只有对风险规避、资金及金融服务提供各种可能的金融支持方式,才能促使我国农业通过走产业化发展道路实现由传统农业向现代农业的转变。 相似文献

地下岩体在开采之前,由于自重和构造所引起的应力是处于平衡状态的,当掘巷道或者进行回采工作时,就破坏了原来应力的平衡状态,使岩体内部应力重新分布,具体表现在巷体周围的煤、岩体产生移动、变形,直到煤和岩体内部形成新的应力平衡状态为止。在煤的开掘过程中,由于采掘活动引起巷道围岩应力集中和重新分配,为了防止围岩变形遭到破坏,需要对围岩进行支护和加固。本文就大断面煤层沿空巷内支护加固技术进行研究,以便为煤矿在开采过程中积累一些技术和经验。 相似文献

This paper proposes a dynamic optimization–simulation model as a decision support system for one-way carsharing organizations. To reduce the vehicle imbalance in one-way systems, a Vehicle Relocation Optimization model is solved successively in a discrete event simulation. Each event is the arrival of a new user. The model is compared to an a priori benchmark model. Autoshare is chosen as a case study. Results show that increasing the reservation time (time between requesting and picking up a vehicle) from 0 to 30 min reduces fleet size by 86%. The model captures a tradeoff between vehicle relocation hours and fleet size. 相似文献

We model the expected support of banks with credit ratings from Moody's and Fitch, taking explicitly into account the capacity and willingness of governments to provide support in case of need, as well as their concerns about moral hazard (i.e., that the expected support may induce banks to assume bigger risks). Our results suggest that moral hazard concerns are relatively weak. In addition, a substantial part of the expected support can be attributed to the quality of a country's institutions. These findings have important implications for the dynamics of banking crises, the value of the ‘fair’ insurance premium banks might be called upon to pay for the expected support, as well as for ways to reduce the resulting negative externalities. 相似文献

“撤县设区”能促进区域发展吗——基于浙江省1993-2013年县际面板数据的分析 总被引:1,自引:0,他引:1
本文通过对国内外学者在县(区)域经济领域十几年研究成果的梳理,整理浙江省原69(现58)个县(市)近30年经济发展的数据,对县域经济进行规模分析和产业结构分析。首次对柯布-道格拉斯生产函数模型改进,把技术增长中重要的因素,即劳动力要素的受教育程度内生化分析,并运用该模型对县域经济和"撤县设区"后区(以余杭市等为例)经济作对比研究,证明"撤县设区"的政策并没有促进区域经济的发展。 相似文献

Professional athletes moving abroad for their career is a novel phenomenon in international human resource management (IHRM). This exploratory article charts the motivations of sports expatriates to move abroad to play, as well as adjustment challenges and sources of support. A survey was conducted with 77 professional athletes in 10 different sports. The main motivations to move abroad were interest to experience life abroad, followed by the search for new challenges. In terms of challenges, different coaching style and communication issues were most often mentioned. Support was mainly informal, through team mates rather than professional providers. Our article contributes to the literature because it is one of the first studies focusing on sports expatriates from an international HR perspective. Our study provides information on a vulnerable group of expatriates; they are young in age and under extreme performance pressure. Sports expatriates need all the support they can get, and yet, little professional support is offered. 相似文献

The present study develops a conceptual framework that sheds light on whether institutional pressures (i.e., normative, mimetic, and coercive) and corporate support can improve innovative behavior across different societies and the moderating role of national cultural dimensions on this link. Our study validated these arguments empirically using data from the 2018 Global Entrepreneurship Monitor (GEM). Data were collected and analyzed from 2,618 respondents. Data were collected through a questionnaire survey of full-time non-managerial employees selected, from different departments of various four- and five-star hotels across five economically and culturally different societies (UK, UAE, Germany, China, USA). Our results indicated that both institutional pressures and corporate support have positive influence on employees’ innovative behaviour. Furthermore, Hotels in cultures with high levels of individualism and low levels of uncertainty avoidance, power distance, and masculinity will indicate higher levels of innovative behaviour in response to corporate support programs. While, hotels in nations with high levels of power distance, collectivism, uncertainty avoidance, and masculinity will indicate higher levels of innovative behaviour in response to normative, mimetic, and coercive pressure. These findings provide important implications for innovative behaviour by developing and validating a multilevel model empirically in the hospitality context. 相似文献
