乡村振兴战略的有效实施离不开金融体系的有力支持,农业保险作为金融支农重要工具在乡村振兴战略实施过程中发挥着重要作用。本文以四川省农业保险发展为研究案例,结合全国农业保险发展概况,点面结合深入分析了农业保险服务乡村振兴的内在逻辑、现状与问题,从乡村振兴依靠主体--老人农业与新型农业经营主体对风险的异质性需求角度出发,论述了农险服务乡村振兴的主要任务。本文认为,现阶段农业保险服务乡村振兴还存在顶层设计不合理、供需错配、目标定位不清导致中长期规划滞后、创新激励不足等结构性问题。基于此,本文提出从中央、省级政府以及保险公司三方出发,采取农险供给侧改革、优化顶层设计、加强农险宣传,提升农户保险意识、探索互助农险合作模式、充分运用互联网高新技术提高风险管控能力等政策建议。  相似文献

政策性农业保险作为重要的支农政策工具之一,除了起到农业风险管理作用之外,从长期来看还具有促进农民增收等效应。本文通过对已有文献进行梳理,讨论了政策性农业保险推广对农民收入增加的作用路径,并基于准自然实验的思路,将我国各省开展政策性农业保险试点作为外生冲击,利用2000~2016年的省级数据,使用渐进性双重差分的方法,评估政策性农业保险推广对农村居民收入以及收入结构的长期影响效果。研究发现,政策性农业保险试点对农村居民人均农业收入和人均非农收入的影响均是正向显著的,并且有助于区域内农村居民非农收入比重提高,这一效果随试点时间推进不断强化。此外,本文进一步检验了政策性农业保险推广对于城乡关系的间接效应,发现政策性农业保险试点对城镇居民收入的影响不大,对城乡收入差距缩小具有一定作用。  相似文献

We provide an interpretation of the productivity dynamics in the manufacturing sector based on the idea of the thick market externality à la Diamond. An econometric model has been estimated which allows to disentangle the long run effects of these trading externalities from those of internal economies of scale and of aggregate industry-level economies. The results obtained—based on a cointegrated system of non-linear-error-correction equations—confirm the hypothesis that the trading externality matters. Moreover, our findings point out that the emphasis generally posited both on internal and external economies of scale is not justified.  相似文献

This paper seeks to explain the productivity growth performance of Malaysia's manufacturing sector using a panel data of 28 industries from 1981–1996. Here, the data envelopment analysis technique is used to calculate and decompose the Malmquist index of total factor productivity (TFP) growth into technical change, change in technical efficiency and change in scale efficiency. This allows the identification of the sources of productivity growth which is crucial for policy formulation. It was found that the annual TFP growth of the Malaysian manufacturing sector was low at 0.8% and this was driven by small gains in both technical change and technical efficiency, with industries operating close to optimum scale.  相似文献

丙烷脱氢制丙烯技术进展   总被引:1,自引:2,他引:1  
丙烯是一种很有应用潜力的无色可燃气态烃。本文综述了丙烷脱氢制丙烯的国内外发展状况,对丙烷脱氢热力学进行了分析:因为该反应为一可逆、增分子、强吸热反应,所以必须采用选择性良好的催化剂,才有利于丙烷选择性的提高;对无机膜反应器中的丙烷脱氢及以氧气和二氧化碳作氧化剂的丙烷氧化脱氢几种丙烯制备方法进行了总结。  相似文献

This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.JEL classification: D24, G21This paper was written while Dogan was a member of Monash University Malaysia.

农业产业化经营中的风险要素及其规避   总被引:1,自引:0,他引:1  
成熟的农业产业化经营在很大的程度上弱化了农业风险。但作为一种尚不成熟的农业产业化经营,潜藏着各种经营风险,包括市场风险、技术风险、违约风险和自然风险。农业产业化经营风险具有客观性、多样性和隐含性,农业产业化经营主体应针对不同风险,采取不同措施,有效化解和规避风险。  相似文献

As the field of strategy reaches its 25th anniversary, we examine how far the field has progressed during that time. Both management and strategy research have been characterized as being in an early stage of development. We draw on Kuhn's ( 1996 ) paradigm development model, which posits a connection between a field's stage of maturity and research processes and outcomes, to assess the maturity of the strategy field. We conduct two studies. The first is a cross‐discipline comparison of productivity norms for university faculty. The second study examines longitudinal research outcomes for a sample of 945 strategy faculty. Our results indicate that strategy has the attributes of both an early stage and mature field: while overall research norms are low relative to other fields, they are driven far more by merit‐based than non‐merit factors.

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.  相似文献
