中国农药施用与农业经济增长脱钩状态:时空特征与影响因素 总被引:1,自引:0,他引:1
[目的]明确农药施用与农业经济增长关联状态及其影响因素,为实现"控药减害增收"的目标提供借鉴。[方法]基于2005—2015年数据利用脱钩理论和对数平均分解指数法分解进行分析。[结果]中国农业经济增长伴生大量农药施用,仅少数省域表现出农药施用和农业经济增长扩张绝对脱钩的理想状态,东北西北部分省域农业经济增长则以更大幅度的农药投入增长为代价。中西部地区劳动力规模和技术进步效应是推动农药施用与农业经济增长脱钩的因素;东部地区种植规模变化、劳动力规模和技术进步因素均是推动农药施用和农业经济增长脱钩的因素;东北地区仅劳动力规模效应成为推动脱钩的力量。[结论]推动农药施用与农业经济增长脱钩需要强化农业科技的创新与普及,完善农业生产过程中的技术支撑,推动农业病虫害监测预警,加大对环境友好型低污染农药和肥料的推广度;构建农户施药的多重约束机制,完善农业病虫灾害保险减少农户对生产过程的风险感知,发挥农业合作社对农户施药行为的规制作用,完善产品分级认证和安全准入制度;通过农地合理流转和农业机械化等方式集约利用农业生产资源;因地制宜推动农药施用与农业经济增长脱钩,结合区域资源优势和农业发展阶段有针对性地设计对策措施。 相似文献

The global logistics industry has grown significantly and logistics has become an important sector of the business economic system and a major global economic activity in recent years. Logistics activities accelerate economic and productivity growth. Efficient logistics is also important to a country’s competitiveness and source of employment. The purpose of this paper is to uncover and understand the major determinants of logistics performance (LP) to further lift the LP of countries. Using unbalanced panel data of 93 selected countries from 2007 to 2014, the present research attempts to critically investigate the major determinants of LP. In estimating the model, this study prefers to use static panel data approach owing to limited data. The findings of the present study reveal that (a) countries with low level of corruption and stable political environment are likely to yield a high level of LP; (b) improvement in resources supply such as infrastructure, technology, labour, and education also have a significant positive effect on LP. Therefore, institutional reforms and upgrading resources will effectively accelerate LP. 相似文献

战术面向服务架构(TSOA)是实现战术云平台服务基础设施的重要支撑概念。由于战术环境的复杂性,目前对TSOA实施过程中面临问题和相关实现技术的总结还较少。为此,开展了针对TSOA的概念以及相关技术的研究。首先,从战术环境下的TSOA架构需求背景出发,介绍了TSOA架构的组成以及适应性特征;然后,通过分析战术环境下设备和网络等多方面存在的限制性因素,明确实施TSOA架构所面临的挑战以及需要解决的关键问题,并对实现过程中涉及的服务发现、消息传输机制、网络状态自适应等相关技术进行归纳;最后,对国内外的相关研究工作进行总结,期望对推动TSOA架构的具体实施提供一定参考。 相似文献

目前国际民航组织(ICAO)和美国航空无线电技术委员会(RTCA)有关广播式自动相关监视(ADS-B)标准中的报文数据源均规定来自全球定位系统(GPS),而中国自主建设的“北斗”卫星导航系统(BDS)作为ADS-B数据源是必然趋势。设计了基于BDS的ADS-B报文生成系统的总体架构,利用BDS接收机接收的真实数据仿真生成了ADS-B的6种报文,并以空中位置报文的生成为例,详细阐述了报文产生涉及的关键技术以及报文的生成过程。通过运行集成后的ADS-B报文生成系统以及对所产生的6种报文的仿真验证,证明该系统总体设计思路合理,运行结果正确,可为基于BDS的ADS-B相关技术研究提供稳定可靠的ADS-B报文源。 相似文献

[目的]开展农业干旱危险性评价与区划研究,为辽宁省西北地区农业防旱抗灾工作提供科学依据。[方法]文章根据联合国国际减灾战略署(ISDR)对农业干旱危险性的定义,分析了构成研究区作物干旱危险性的致灾因子和孕灾环境因子,采用层次分析法确定了各因子的权重,构建了研究区农业干旱危险性评价指标和模型。以2009年为例,通过利用降雨、土壤、农业生产类型及地形等数据计算了辽西北地区农业干旱危险性评价指数,利用自然间断点法分级干旱危险性评价指数,并借助GIS技术,绘制研究区农业干旱危险性等级区划图。[结果] 2009年作物生长期间研究区农业干旱危险性由高到低排列为:朝阳市葫芦岛市锦州市阜新市铁岭市沈阳市。[结论]辽西北地区农业干旱危险性等级区的划分,能够帮助政府管理部门为面临干旱威胁不同的区域建立适当的防灾方法和有效的应急预案。 相似文献

Chinese tourists' views of nature and natural landscape interpretation: a generational perspective 总被引:1,自引:0,他引:1
This study investigates Chinese tourists’ views of nature, interest in animal experiences and their preferred natural landscape interpretation content from a generational perspective. Eight hundred and eight self-administered questionnaires were collected at Wulingyuan, a UNESCO World Natural Heritage Site, in China. It suggests that overall Chinese traditional cultural values and beliefs, notably the thinking of tian ren he yi (oneness of nature with humans), still have considerable impacts on Chinese tourists. They were found to have a strong sense of connection with nature and a preference for cultural interpretations of natural landscapes. Meanwhile, Chinese might be reaching a point of convergence in terms of attitude towards nature and animals with their Western counterparts, as reflected by their weak anthropocentric view, and strong ethical and aesthetic appreciation of animals, regardless of generation cohorts. Yet, the study shows significant generational gaps: older generations have a stronger connection with nature, are more concerned about environmental issues and show more support for the Western approach towards nature protection; the younger generations hold weaker anthropocentrism, and are more interested in animals, yet are less likely to learn about nature through tourism interpretation. 相似文献

We describe a model that predicts an asymmetric impact of disclosure on investor uncertainty. We show that good news tends to resolve more uncertainty than bad news, and that uncertainty can be revised upwards if the investors' prior belief is sufficiently strong and the signal is sufficiently bad. This result is in contrast to classical disclosure models, where new information always resolves uncertainty and the change in uncertainty depends only on the relative precision of the news. Using option-implied volatility as a proxy for uncertainty, we find strong support for our predictions. We also show that our results are robust to competing explanations, notably to the leverage effect and volatility feedback, as well as to the jump risk induced in anticipation of the earnings announcements. 相似文献

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors’ satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors’ satisfaction and lending intention. Some specific features of China’s online lending market are identified, which provides valuable insights for online lending platforms and the government. 相似文献

This paper examines the effects of idiosyncratic accounting information on a firm's cost of capital. By embedding a moral hazard problem into a multifirm asset‐pricing model, I show that moral hazard distorts the sharing of idiosyncratic risk but does not affect the sharing of systematic risk in the economy. A firm‐level improvement in idiosyncratic information reduces the firm's cost of capital even though it does not affect the implied cost of capital inferred from publicly traded shares. Moreover, an economy‐level improvement in idiosyncratic information reduces the risk premium for idiosyncratic risk but increases the risk premium for systematic risk, resulting in an ambiguous net effect on the firm's cost of capital. These results provide alternative explanations for the mixed empirical evidence on the relation between information quality and the cost of capital. 相似文献
