我国农用地资源态势分析与对策建议——基于国家农业资源台账

[目的]为切实解决我国长期面临的农业资源禀赋家底不清楚、农业资源更新不及时、基础数据共享不充分等实际问题,中国农业科学院农业资源与农业区划研究所率先启动了"国家重要农业资源台账数据"系统建设和服务应用。[方法]文章在国家重要农业资源台账数据基础上,根据研究内容与分析要求,甄选出了典型样点县(市)农用地资源数据库(2010~2015年),作为农用地资源态势分析和研究的依据。[结果](1)耕地、林地是典型样点县农用地主要类型。耕地主要分布在我国中东部地区,占土地总面积均在40%以上。2010~2015年,全国各样点农用地结构均发生了明显变化。耕地呈现总体增加的态势,年均增长率为1.76%,主要分布在土地后备资源较丰富地区,耕地减少的地区主要在快速发展的中部区域。(2)2010~2015年耕地质量呈现整体下降态势,这种趋势在我国中部经济增长较快的地区尤其明显。草地、园地面积均有明显减少,年均减少2.10%和2.02%。(3)分析土壤有机质含量平均值、全氮含量平均值、速效钾含量平均值及土壤pH发现,东北地区样点的有机质含量高,由北向南逐渐降低;南部地区的土壤全氮含量、有效磷含量较高,华北地区普遍偏低。土壤速效钾含量最高的地区分布在中部地区,而南部土壤速效钾含量较低。中部地区的p H普遍偏高,土壤呈碱性,南部及北部地区的pH偏低,土壤多为酸性。[结论]近些年来我国耕地数量保持稳定甚至有所增加,但耕地质量下降的问题不容忽视。从提高农业综合生产能力、促进农业农村可持续发展的战略高度,亟须进一步加大农用地资源整治与保护力度,加快国家农业资源基础数据建设与共享,加强农业资源利用领域前沿的技术方法和科学决策研究,为新时代农业农村优先发展、推进农业现代化提供参考依据。     

A trivariate model of participation,fertility and wages: the Italian case

Italy has unusually low fertility by OECD standards, accompaniedby unusually low female participation in paid work. This paperaddresses the issue of the empirical relationship between fertility,female participation in the labour market and wages with theseItalian 'peculiarities' as a backcloth. A trivariate model ofparticipation, fertility and wages has been constructed andestimated using three pooled cross-sections of Italian microdata, allowing for the identification of cohort effects. Thismodel follows a 'purist' approach: the participation and fertilitydecisions, as well as the wage equation, are modelled as completelyjoint. The cohort effects turn out to be significant: the pointestimates do not appear to confirm actual trends, which arenegative for fertility and positive for participation. The femalewage is the most important variable influencing the propensityto have children and the propensity to participate in the labourmarket, casting doubt on suggestions that observed trends arethe products of shifts in women's 'tastes'.

中美注册会计师制度变迁差异的经济学思考

一、中美注册会计师制度变迁的类型差异分析根据制度经济学的原理，制度的变迁可以分为强制性制度变迁和诱致性制度变迁。强制性制度变迁是指通过行政权力和立法手段等外在强制力推行制度、变革制度的一种制度变迁方式。而诱致性制度变迁是指通过一种环境的自发力量产生的诱导力推行制度、变革制度的一种制度变迁手段。我国的注册会计师制度变迁具有强制性制度变迁的属性。自１９８０年我国开始恢复注册会计师制度以至发展成熟，无不渗透着国家的强制性。最初财政部于１９８４年９月２５日发布了《关于成立会计咨询机构问题的通知》，规定设…     

品牌如何和客户说再见
