[目的]研究第二次土地利用现状调查以来山东省生态用地变化特点及驱动因素,评价各类驱动因素对生态用地的影响程度,为科学编制区域空间规划,保护和合理利用生态用地提供参考。[方法]文章构建了全省生态用地转移矩阵,归纳了影响生态因素变化的主要驱动因素,提出了驱动力指数计算方法,定量分析和比对了各驱动因素对生态用地的影响。[结果]2009—2017年生态用地共计转出2048万hm2,占生态用地总面积的472%; 转入316万hm2,占生态用地总面积的072%。8年来全省生态用地净减少1732万hm2,占2009年生态用地总面积的400%。生态用地的流向以耕地最多,向城镇村及工矿用地流出次之,向设施农用地的流出也有较大面积。[结论](1)在影响生态用地变化的六大驱动因素中,耕地开发和城镇村工矿占用的驱动力指数最高,非耕农业占用对生态用地的变化有一定影响。(2)六大因素中城镇村工矿占用对当地生态环境的破坏力最强。  相似文献

学界对于信访分类治理的研究大多基于因“人”分类或因“事”分类展开,形成了信访分类治理研究的基本范式。然而,社会心理服务嵌入信访治理体系,为信访分类治理提供了新的视野:因“心”分类,即按照信访人“心理诉求——利益诉求”的两分原则,将信访人分为利益型、心理型、耦合型和无意识型四种。本文以西平县信访治理实践为个案,提炼出由“心”而治的信访分类治理模型,并对该模型的治理理路进行了分析。研究发现:地方政府对信访频次、情绪和事件的三维叠加形成了信访分类治理的参照维度,而地方政府对治理技术的灵活性运用则构成了信访分类治理的动态实践。本文为信访分类治理过程中信访人的心理诉求与利益诉求间的关系提供经验事实,并为社会心理服务驱动下的信访分类治理理路提供分析框架。然而,受限于研究区域和案例数量,本文提炼出来的由“心”而治的信访分类治理模式还有待进一步验证和完善。  相似文献

Despite reductions in poverty generally, recent trends in Latin American countries show processes of both de-feminization and re-feminization of poverty. A rise in the numbers of women to men living in income-poor households has occurred despite feminized anti-poverty programs, most notably conditional cash transfers (CCTs), which target resources to women. This paper shows that methodological differences in what, how, and who is the focus of measurement may influence patterns of poverty “feminization.” It also suggests that feminized policy interventions might in themselves be playing a role in the re-feminization of poverty, not least because of data and definitional limitations in the way female-headed households and, relatedly, women’s poverty are understood. The somewhat paradoxical interactions between the feminization of household headship, the feminization of poverty, and the feminization of anti-poverty programs present interesting challenges for redressing gender gaps in poverty within the 2030 Agenda for Sustainable Development.  相似文献

Existing research on private label market share is primarily in the context of the Western market. The Chinese market context research is scarce, although private labels are developing rapidly in the past several years. This study investigates how the average wage and number of stores affect the Chinese market's private label market share. More importantly, this paper examines the moderating effect of the average wage and the number of stores on the relationship between the private label market share and product assortment as well as the relationship between the private label market share and pricing. Data collected from a Chinese supply chain dyad is analyzed to study category management using hierarchical linear models. The results reveal that the average wage and the number of stores positively affect the private label market share. Furthermore, the average wage enhances the negative effect of the number of brands, weakens the negative effect of the private label price, weakens the positive effect of national brand price. Meanwhile, the number of stores enhances the positive effect of the SKU proliferation of private label, enhances the negative effects of the number of brands, and enhances the negative effect of the private label price. This study contributes to category management. Furthermore, the findings will be valuable to domestic and international grocery marketers and retailers operating private labels in China.  相似文献

2019 is the 70 th anniversary of the founding of the people’s Republic of China and the key year for implementing the rural vitalization strategy.Summarizing the great achievements made by agriculture and rural areas in the past 70 years will have an important theoretical value for promoting the modernization of agriculture and rural areas and the strategy of rural revitalization.Under such circumstances,the 10 th member congress and 2019 academic seminar of CAAE was successfully held in Beijing.The key to promote rural revitalization lies in deepening rural reform,focus on the property right system and market-oriented allocation of factors,and establish a system and mechanism of free circulation and equal exchange between urban and rural areas.In order to promote the organic connection between small-scale peasant and the modern agriculture,it is necessary to speed up the development of agriculture social service industry.Finally,it is suggested to adhere to the two-wheel drive of rural revitalizationand new urbanization,promote the effective coverage of rural public services,and improve the rural governance mode of combining autonomy,rules of law and virtue.  相似文献

The introduction of automated vehicles (AVs) is a virtual certainty. Much less certain is the timing of their introduction and how rapid the transition to full automation will be. Various governments are already working to facilitate this shift by, for example, amending and elaborating regulations to support the introduction of AVs, or supporting tests in different urban environments. Meanwhile, urban and regional planners and decision-makers are still grappling with the uncertainties and differing opinions about the possible impacts of AVs on land-use changes and location choices, particularly in relation to the space available for vehicles, both moving (i.e. roadspace) and stationary (i.e. parking space). This paper uses a backcasting approach to identify critical policy decisions and measures to be taken before the implementation of AVs, so as to achieve a more desirable, attractive and high-quality city. These policy measures primarily relate to the reuse and reallocation of parking and roadspace. Two strategic decisions are found to be essential to meet the major goals of sustainable and liveable cities: a clear commitment to a shared mobility and the delimitation of Core Attractive Mixed-use Spaces (CAMS). In order to deliver these desired urbanisation patterns, a set of three policy paths, involving eight policy packages, is proposed for the next 20–30 years. This article provides urban and regional decision-makers with examples of interventions that can be implemented beyond and during the implementation of AVs.  相似文献

长期以来,人们只看重货币国际化结果,以占全球贸易计价结算比重、外汇交易比重、国际债券比重、外汇储备比重等相关指标衡量一国货币的国际化程度,而忽视货币跨境流动放松过程,即一国货币的跨境流动自由化程度。货币国际化是一个过程又是一种结果,包含进程和结果两个层面,在货币国际化进程中,过早过快放松本币流出入会引发经济金融风险,某些情形下进程比结果更值得关注。构建人民币跨境自由度指数涉及强度赋值、项目设置和权重确定三方面内容。在梳理2019年第2季度前我国货币政策基础上,对2008年至2019年经常项目下的人民币跨境流动自由度、证券投资项目下的人民币跨境流动自由度以及资本项目下的人民币跨境流动自由度进行评估,并以美国近5年各项目下的资金流动平均占比为权重,构建了人民币跨境流动自由化指数,考察2008—2019年人民币跨境流动自由化程度,结果显示人民币国际化进展较快,跨境流动已得到很大程度放松,而且人民币流入自由程度显著高于流出自由度。我国人民币国际化进程应持续遵循先经常项目后资本项目、先流入后流出、先机构后个人、先大额后小额、先风险小项目后风险大项目的次序,提高人民币跨境流动的稳定性,降低无序流动的投机风险;严格管控证券投资、其他投资、衍生品项目下人民币跨境流动,并依据我国利率市场化程度、金融市场发达程度及审慎监管能力进行调整;大力提升经常项目的人民币结算比重,发展人民币离岸市场,提高非居民间的人民币使用频率和使用规模;充分评估各项目下人民币跨境流动和本外币兑换自由度,提高两者的协同匹配程度,降低因两者不匹配而产生的负面影响。  相似文献

2019年是中华人民共和国成立70周年,也是物流业稳中有进、变中求新的一年。面对严峻形势,我国物流业顶住下行压力,实现平稳运行,取得多方面进展。具体而言,一是社会物流需求增速持续放缓,总体运行缓中趋稳;二是物流需求结构持续优化,物流供给结构稳步升级,供需结构加速调整;三是科技应用引领数智化转型,科技赋能物流数智化、平台化;四是新兴的供应链服务企业向标准化发展迈出了重要一步,供应链创新发展进入新阶段,现代供应链成为新亮点;五是物流基础设施网络加快升级,物流枢纽网络建设进入实质推进阶段,助力枢纽经济发展;六是物流业"走出去"空间加大,国际物流打开对外开放新局面,我国对外投资合作与对外援助执行保持平稳有序健康发展;七是绿色物流配合污染防治攻坚战,绿色可持续物流取得新进展;八是物流政策落地,物流企业获得感增强,从业人员稳定性增强,物流营商环境持续改善。2020年,我国经济稳中向好的基本趋势不会改变,物流业平稳增长的总体方向不会改变,物流业主要经济指标将继续保持平稳增长,但物流业下行压力依然较大,发展不平衡、不充分矛盾依然比较突出,与人民群众日益增长的美好生活需要和现代化经济体系建设的要求相比依然存在差距,高质量发展任重道远。在新的一年里,为更好地推动我国物流业发展,一要平衡物流稳增长与高质量发展关系,决胜全面建成小康社会;二要坚持目标导向,探索新时代物流业发展的新使命新要求;三要突出新发展理念,推动传统数量型降成本向效率型降成本转变;四要深化产业联动融合,从低水平粗放式发展向精细化、高品质发展转变;五要坚持科技引领和技术驱动,激发物流业高质量发展新动能;六要推进国家物流枢纽联盟工程和全国百家骨干物流园区互联互通工程,建设物流基础设施网络;七要配合"一带一路"倡议,推动国际物流合作与交流;八要进一步处理好政府与市场、国家与地方、市场与企业的关系,营造政府、企业与协会合力推动物流业高质量发展的产业生态圈。  相似文献

财务风险是企业调整发展战略、提升管理水平的重要参考指标之一。财务风险预测模型的建立能够预测企业在中短期内的财务风险,为企业敲响警钟。以造纸业上市公司冠豪高新为例,选取近五年财务杠杆系数为风险指标,建立GM(1,1)风险预测模型,结果显示该公司短期内财务风险呈下降趋势,调查发现这主要得益于产品成本的降低以及营销策略的改变。  相似文献

What does a community‐centric approach to impact assessment look like? That is the central question addressed in this article. Our community‐centric perspective provides an alternative to discipline‐centric approaches to impact assessment that emphasize specific methodological gold‐standards (e.g., randomized controlled trials [RCTs] in development economics). Disciplinary approaches to impact assessment owe their principal allegiance to the discipline's knowledge‐creation norms. Consequently, the concerns, interests, and voices of community members are not fully captured in the impact assessment process. In this article, we flip the conventional perspective to offer a community‐centric view of impact assessment that places the concerns, interests and voices of community members front and center. We present the case for why we need a community‐centric approach to impact assessment and clarify its axiological content, theoretical perspective, and methodological stance. Specifically, we advocate for a relational axiology, a system‐theoretic perspective, and a phenomenological methodology.  相似文献
