The existing evaluation system for power grid investment in China has not combined measures of the investment benefits and investment efficiency very well and it lacks practical reference value. This article proposes an improved evaluation index system of the benefits and efficiency of power grid investment projects. The system divides the evaluation method into indexes. This includes the basic indexes, modification indexes, and appraisal indexes that evaluate the economic and environmental benefits of the investment projects comprehensively. It considers the overall efficiency in terms of the economy, technology, and society. It combines an absolute efficiency evaluation model with a data envelope analysis relative efficiency evaluation model. Finally, the benefits and efficiency of investment of an actual power grid project are evaluated through a case study. The results show the practical value of the proposed efficiency evaluation method for evaluating investment projects in a power grid. 相似文献

In this study, an epsilon-based network data envelopment analysis is employed to construct assessment mechanisms for government performance. Moreover, performance indicators of two dimensions of tax collection efficiency and financial effectiveness are measured. We propose a vector autoregression model in which all economic variables are regarded as dependent variables to address the disadvantages of traditional regression model. The conclusions are as follows: (a) measures of tax collection efficiency deteriorated, whereas those of financial effectiveness improved. (b) In an impulse response analysis of the model, an increase in government-published land values produced significantly increased tax collection efficiency. 相似文献

We study investor communication and stock comovement using a novel data set from an active online stock forum in China. We find substantial comovement among the returns of a stock and its “related stocks,” which are frequently discussed in the subforum dedicated to the given stock. Comovement is greater when the discussion of related stocks is more intensive. Further, the effect of communication on comovement is stronger for stocks associated with higher information uncertainty. Codiscussed stocks are more actively traded and experience more correlated trading. A trading strategy that exploits communication‐driven comovement generates abnormal returns. Our findings highlight the impact of investor communication on asset comovement. 相似文献

零售业自营与联营之争由来已久,在当前供给侧结构性改革、完善促进消费体制机制以及零售业寻求创新发展的背景下,有必要对这一问题展开进一步的理论探讨。文章结合马克思流通经济理论指出,自营和联营的本质区别在于是商业资本还是产业资本承担商品流通职能,自营和联营并不是非此即彼的互斥关系,但如果零售业完全倚重其中一种模式并在全社会推向极端,则需要反思商业资本和产业资本是否各得其所和高效分工。在中国流通体制变革中,虽然联营模式在特定历史时期帮助众多零售企业渡过生存危机并推进内资零售快速扩张,但发展至今,已呈现零售业普遍联营的情况,使零售业整体面临着制约创新发展的新问题。数字经济为零售业回归自营提供了有利契机,零售企业应充分利用新技术摆脱联营制的路径依赖,依托数字化开展深度自营并全面提升流通效率。 相似文献

Mobile channel additions have been shown to increase consumer-brand relationships, brand satisfaction towards and overall purchasing from a retailer, but what is less apparent is whether shareholders are fully rewarded for retailers’ mobile channel additions. Results from an event study on 115 announcements relating to mobile app additions of publicly traded U.S. retail firms between 2009 and 2016 indicate that the stock market responds generally positively to mobile app additions, but specifically to the two mobile app addition types. Stock market responses to search-related and purchase-related app additions are moderated by firm size, product category, and target customer age. For announcements of search-related apps, the market responds more positively to product retailers than to service retailers, and to small firms than large ones. For announcements of purchase-related apps, the market responds less positively to firms that target younger customers than firms who do not especially target them. 相似文献

We investigate whether firms restructure board composition to align with changes in their contracting environment. Board size and independence increase with firm complexity, consistent with theoretical predictions. However, the hypothesized negative relation between board independence and information costs is evident only for firms completing acquisitions. Furthermore, board independence increases to offset increases in CEO power in a sample of firms making acquisitions, but decreases when CEO power increases in a large cross‐section of firms. We conclude that after the Sarbanes–Oxley Act of 2002, firms face constraints adjusting to target board structure, but these constraints can be mitigated by a shock to the contracting environment via acquisition. 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
