GDP已经成为世界公认的衡量经济增长速度的指标,但它只是单纯从数量上反映经济增长。GDP外部质量特征主要体现在年平均发展速度、年地区发展的离散系数上;内部质量特征则包括支出法构成、收入法构成、三次产业构成、要素的贡献率、能源和原材料消耗等方面。应综合GDP的内部质量指标和外部质量指标编制GDP综合质量指标评价体系,弥补单一GDP指标的不足。 相似文献

随着后疫情时期的到来以及经济高质量发展的不断推进,承德产业分工受到了较大影响。增强经济“韧性”,加速产业空间集聚,成为承德后疫情时期经济战略方向的重要考量。论文通过构建VAR模型,实证研究承德产业集聚对经济高质量发展的动态效应,结果表明:产业集聚对经济高质量发展具有周期性循环往复效应,制造业与公共服务业集聚效应显著,制造业专业化集聚的贡献率最大。因此,要加大对制造业、公共服务业等产业的支持力度。 相似文献

We examine whether gender diversity of chief executive and chief financial officers (CEOs and CFOs) is associated with financial reporting quality. The CEOs and CFOs of publicly traded companies are both required to certify the appropriateness of their financial statements and annual disclosures. We argue that gender diverse dyads (groups) of executives can bring different perspectives and professional skepticism to financial reporting. Using a sample of different CEO/CFO gender dyads during 2006–2019, we postulate and find evidence of higher accruals quality among firms led by gender-diverse dyads compared to accruals quality reported by firms led by all-male CEO/CFO pairs. Additional analyses reveal that the auditors of firms with gender-diverse executive dyads issue audit reports later, charge higher audit fees, and are more likely to be one of the Big 4 firms. These findings support the view that top executive gender diversity enhances financial reporting quality, which has important implications for corporate governance mechanisms. 相似文献

We examine the impact of CEO power on reading difficulty of corporate annual reports. We find that CEO power is positively related to reading difficulty, implying that annual reports of corporations with powerful CEOs are difficult to read and understand. More importantly, we find that the relation between CEO power and reading difficulty is moderated by earnings performance or corporate governance. Additional findings suggest that this relation becomes stronger for firms with lower financial reporting quality or for CEOs with shorter tenure. Our study not only joins the debate on the consequences of powerful CEOs but also uncovers several factors that moderate the relation between CEO power and annual report reading difficulty. 相似文献

This paper proposes an asymmetric autoregressive conditional duration (ACD) model, which extends the ACD model of Engle and Russell (1998). The asymmetry consists of letting the duration process depend on the state of the price process. If the price has increased, the parameters of the ACD model can differ from what they are if the price has decreased. The model is applied to the bid-ask quotes of two stocks traded on the NYSE and the evidence in favour of asymmetry is strong. Information effects (Easley and O'Hara 1992) are also empirically relevant. As the model is a transition model for the price process, it delivers `market forecasts' of where prices are heading. A trading strategy based on the model is implemented using tick-by-tick data.While remaining responsible for any error in this paper, the authors would like to thank R. Anderson, G. Le Fol, C.

In this note, we revisit minimum quality standards (MQS) under a vertically differentiated duopoly. We generalize the model in Ronnen (1991) and Valletti (2000) by introducing asymmetry into the fixed cost of quality improvement and by explicitly taking into account the endogeneity of quality ordering. In the generalized model, we show that the results derived by Ronnen (1991) and Valletti (2000) are largely robust. 相似文献

非国有经济发展对中国经济增长质量影响机理研究——来自VEC模型的新证据 总被引:1,自引:0,他引:1
转轨以来,中国非国有经济的发展促进了经济增长的数量扩张.这是因为,经济非国有化改革作为一种制度创新,是一种增量式改革.这种改革使得体制内利益在未受影响的条件下,实现了帕雷托式的增长.然而,非国有经济的发展并没有带来中国经济增长质量的同比改善.这是因为,中国民营企业发展一般都过分强调以利润为中心,忽略环境成本,并且由于融资困难等因素导致了其技术创新能力的弱化;其次,中国引进的外资不仅在技术和管理创新的扩散效应上没能达到预期效果,而且日益增加的加工贸易通过转移定价方式使中国经济不能充分享有出口增长带来的利润贡献. 相似文献
