[目的]通过深入研究黄土丘陵区贫困人口生计资本对生计活动的影响,为解决农村贫困问题,提升农户生计资本存量、实现区域可持续生计发展提供科学依据。[方法]文章以甘肃省榆中县为例,基于对榆中县农户的调查数据,采用熵值法分析了东北部山区、中部川区和西南部山区贫困人口的生计资本状况和生计活动方式,并对其生计活动进行评价。[结果]从农户的生计资本组合来看,榆中县整体自然资本和人力资本相对物质资本、金融资本、社会资本3类资本较为富裕,尤其在西南部山区和东北部山区3类资本缺乏型农户比例较高。中部川区各乡镇人口的总体生计资本状况较好,总指数最高,而西南部山区次之、东北部山区最低,两者生计资本状况总体匮乏。农户的生计活动主要以种植、养殖和外出打工为主,生计活动多样性程度偏低; 中部川区人口的生计活动多样性指数最高,西南部山区次之、东北部山区最低,且整体受教育程度偏低,加之物质资本、金融资本、社会资本缺乏进一步限制了当地农户的生计多样性。[结论](1)针对不同生计资本水平和生计活动多样性程度偏低的贫困地区,需要进一步发挥民族文化产业扶贫优势,开启地域产业扶贫新模式,打造地域无公害特色农业产业品牌,提高农户物质资本边际贡献; (2)发展小额信贷金融服务,改善农户金融资本存量,预防村际农户金融资本二元极化; (3)实施免费教育培训技能学习,打造教育培训脱贫示范村,提高人力资本存量,缓解贫困人口生计压力等提高经济发展水平的扶贫政策措施。  相似文献

This study seeks to examine and unearth antecedents to co-creation behaviours within a U.S. retail banking context. A critical aspect for marketing managers and academics alike, co-creation has a strong influence on tangible factors such as profit and intangible factors such as referrals, satisfaction and feedback. Antecedents were identified as trust, customer engagement and participation attitude whilst social media usage was a consumer characteristic identified as influencing co-creation. Data was collected from 489 U.S. retail banking customers via an online survey. The data was analysed via structural equation modelling. The findings indicate that customer engagement influences trust, co-creation and participation attitude. Participation attitude was found to influence trust and co-creation but trust had no direct effect on co-creation. The study further found that social media usage intensity influenced co-creation behaviours. The findings contribute in three ways. First, this is one of the first studies to scrutinise participation attitude in an attempt to explain co-creation behaviours for U.S. banks over social media. Second, identification of precursors to value co-creation has been ascertained in a U.S. retail banking social media context. Third, the study additionally contributes to the findings that social media usage has a moderating effect in value co-creation and offers a potential segmentation strategy.  相似文献

The value relevance of comprehensive income (CI) compared to net income (NI) remains unresolved. We look at this issue in the Canadian market, using association methods to determine the value relevance of reporting CI and other comprehensive income (OCI) components for stock prices and returns. The sample consists of all the firms in the S&P/TSX Composite Index that prepared their financial statements according to Canadian standards or International Financial Reporting Standards (IFRS) over the 2008–2016 period. Although we find no evidence that CI is more value relevant than NI for stock prices and returns, we note that some OCI components are incrementally value relevant beyond NI for both amounts. In addition, financial services firms differ from other companies in terms of the relationships between some of their OCI components and prices or returns, with such firms even driving some relationships. Relationships between OCI components and prices or returns are also affected when data from the financial crisis period are excluded, with some relationships even changing after IFRS adoption. These results inform Canadian standard setters and financial statement users that OCI components are decision useful for the Canadian market.  相似文献

When regulating foreign direct investment (FDI), countries often face a trade-off between pursuing national policy interests and suffering efficiency losses due to FDI restrictions. We demonstrate the presence of this trade-off in the case of a protectionist FDI policy in Indonesia. Using a yearly census of Indonesian manufacturing firms from 2000 to 2015, we link product-level changes in binding FDI regulation due to major regulatory tightening to changes in firm-level productivity. Controlling for an extensive set of fixed effects as well as potential political economy drivers of regulation, we show that a tightening of the regulatory environment was successful in reducing foreign capital reliance among regulated firms, and led to increases in FDI among non-regulated firms producing the same product. Despite compensating increases in domestic capital, regulated firms experienced relative productivity losses. This points towards either a less efficient allocation of domestic capital or a general inferiority of domestic capital as compared to foreign investments.  相似文献

以创新生态系统为视角,引入创新资源互动与生态系统规范机制为中介变量和调节变量,探究价值共创如何影响企业创新绩效。基于307家企业样本数据,运用结构方程模型、Bootstrap和层级回归方法对数据进行分析。研究发现:创新生态系统中,价值共创不完全直接影响企业创新绩效;创新资源互动部分中介价值共创对企业创新绩效的影响;生态系统规范机制部分正向调节价值共创对创新资源互动的影响。最后提出,创新生态系统调控方与企业要差异化地制定提升创新绩效的实施方案,营造活跃的创新资源互动氛围,形成并完善系统内生态规范机制。  相似文献

合理的技术价值界限是理性决策的依据。对于复杂的新技术,尤其是后果不确定技术,不同主体间价值认知分歧直接导致价值界限不清,成为理性决策的难点。以保罗的实用对话伦理理论为认知路径,讨论此类技术价值分界方法。通过比较功利主义、自由至上主义在价值认识和判断上的后果差异,揭示后果不确定技术价值在不同主体间漂移的原因,探索在不同价值主体间产生伦理维度的技术价值界限方法。在开放式语义环境中,不同价值主体之间的共识即是技术价值的伦理界限,可为决策公正提供伦理支撑,避免因主体缺失而导致在应用中发生技术价值过度偏失和决策失当,为我国发展诸如转基因水稻等后果不确定技术决策提供可操作性的方法论借鉴。  相似文献

基于价值链视角,构建涵盖人才资源在区域空间层面集聚生成、地区配置、效能产出3个维度在内的区域人才集聚水平评价指标体系,采用专家咨询AHP-信息熵组合赋权法构建综合评价模型和耦合协调度模型,对2010—2018年长江经济带沿线省市人才集聚水平进行测度与时空演化特征分析。结果表明,就长江经济带整体而言,考察期内地区人才集聚水平总体呈现逐年上升态势,但仍处于低水平状态;沿线省市人才集聚水平差异显著,缩小趋势渐缓,整体呈现局部高水平、全局低效率的不利境况;各省市人才集聚水平关键维度的耦合协调度整体呈显著波动递增态势,但内部耦合协调度存在不平衡发展问题,影响地区人才集聚水平整体提升。为提升长江经济带人才集聚水平,推进沿线地区协调发展,需强化区域人才合作机制,采取差别化精准策略破解沿线地区人才集聚低水平、不协调的短板因素。  相似文献

This paper explores the determinants of the individual's decision to perform cross-border e-commerce (CBeC). The European Union (EU) is especially interested in the promotion of CBeC because it is an important tool in its strategy to achieve the Digital Single Market in Europe. In this paper official data is used from a representative survey of 16,209 individuals on ICT usage by households and individuals that was carried out in Spain by the National Institute of Statistics (INE) for the year 2016. Using a standard neoclassical utility maximization framework, and logistic regression techniques, the results show that being a male is positively related to the probability of practicing CBeC. Education is positively and significantly related to the probability of being involved in CBeC with EU countries. Computer and Internet Skills are significant and positive factors in explaining CBeC (either with EU countries or with the rest of the world). The variable “how often the consumer sees other customer reviews before buying online”, has a positive effect. Foreign nationality also increases the likelihood of using CBeC. To promote CBeC in Spain measures towards developing digital skills, Internet trust and use of online information reviews of goods and services are discussed.  相似文献

过去几十年来,国际生产的增长主要是通过跨国并购的模式实现。不过以前的研究主要集中在运用行业和企业层面的因素来探讨FDI的进入模式。邓宁(2009)强调宏观经济变量可以解释FDI,并呼吁进行更多的研究,以提高我们对宏观经济变量影响重要性的认识。在前期研究的基础上,文章采用2006-2012年6534起中国企业并购交易作为样本,分析中国企业跨国并购交易的决定因素。借鉴诺思的制度理论框架,探讨中国和东道国的正式制度与非正式制度对中国企业发起跨国并购可能性的影响。文章研究的重点在于国家宏观经济和投资者保护状况对中国企业进行跨国并购交易的可能性的影响。通过单因素分析和logistic回归分析发现,中国宏观经济的发展和目标企业所处的商业环境越好,越会促进中国企业跨国并购的可能性。实证结果还显示中国对投资者保护强度越大,中国企业进行跨国并购的可能性更小。  相似文献

Important changes have happened to the upstream segment of the coffee sector in Ethiopia - Africa’s biggest - in the last decade, as illustrated by the increasing adoption of improved production, harvest, and post-harvest practices. Upstream marketing has also improved and there have been large investments in processing capacity, shown by the extended coverage of wet mills. These improved practices are shown to be associated with positive impacts on coffee productivity and prices. Changes appear to be linked with multiple factors including local market reform, greater presence of public extension agents, high international prices, and a push for certification by international buyers. On the other hand, a combination of production (lack of improved seedlings, weather and disease shocks) as well as institutional issues (saving constraints and lack of vertical integration and traceability) have seemingly impeded more widespread uptake of improved practices and therefore better farm performance. The study illustrates the significant complexity in obtaining transformation at the farm level in these settings.  相似文献
