目的 由于成都市温江区和崇州市农地经营权抵押贷款类型均属自上而下的政府主导型,可将两地进行合并讨论政府主导型农地经营权抵押贷款对农户收入效应的影响,同时相较崇州市,成都市温江区在担保和抵押物处置环节引入第三方参与而更趋于市场化运作,因此将两地进行对比分析以进一步探讨第三方参与是否会使农户信贷约束和收入效应产生显著差异。方法 文章将成都温江和崇州市作为研究区域,通过实地调研共获取249个样本,采用倾向得分匹配—双重差分法(PSM-DID)探讨政府主导型农地经营权抵押贷款对缓解农户信贷约束、增加收入的影响。结果 政府主导型农地经营权抵押贷款能缓解农户信贷约束、增加农户户均总收入、户均农业收入和户均非农收入,且引入第三方参与的温江区相较崇州市在信贷约束缓解程度、农户收入提升方面表现更优。结论 应大力推广政府主导型农地经营权抵押贷款和积极引入第三方参与,以扩大农地经营权抵押贷款规模,促进农户增收和释放土地红利。 相似文献

以2010年3月31日我国首次推出融资融券制度为研究背景,以事件前后一年的季度数据为研究样本,采用双重差分模型(Difference-in-Differences Model)实证检验了融资融券能否有效抑制标的股票管理层的盈余管理行为。研究发现,融资融券制度推出以后,无论我们采用更换样本、更换变量还是分样本回归,实证结果均未发现融资融券能有效抑制标的股票管理层的盈余管理。虽然如此,但研究仍可以丰富国内这方面的文献并为相关争议文献提供进一步佐证,更重要的是,研究结论可为政策制定者完善后续政策,进一步深化改革提供一定的经验证据和理论基础。 相似文献

China's carbon emissions trading (CET) policy aims to force relevant enterprises to implement low‐carbon technology innovation and address environmental challenges through marketization means. However, how China's CET policy may affect enterprise technology innovation and whether this effect may differ in industries remain to be further investigated. Therefore, based on the panel data of listed enterprises covered by the CET policy in China during 2009–2017, this paper employs the difference‐in‐difference (DID) and DID‐based propensity score matching models to evaluate the effect of CET on technology innovation. The empirical results indicate that the effect of China's CET on the technology innovation of related enterprises is generally not significant during the sample period, but this effect presents evident industrial heterogeneity. Specifically, among the eight CET‐covered industries, the CET policy helps to improve technology innovation for power and aviation enterprises but not in the other six industries (i.e., steel, chemical, building material, petrochemical, nonferrous metals, and paper), which implies that China's CET policy still has great potential for promoting the technology innovation of related enterprises. In addition, the central findings remain robust when the system generalized method of moment and DID‐based coarsened exact matching models are applied to consider the influence of omitted variables, unobservable confounders, and different matching methods. 相似文献

This paper investigates the effect of global sourcing on firm performances by using data on Danish manufacturing firms during the period 1995–2006. The results show that firms with better ex-ante characteristics are more inclined to source intermediate inputs from abroad. The results also show that firms that source from different locations possess different ex-ante characteristics; the most productive source inputs from high-wage countries while capital stock and being an exporter are more important factors when sourcing from low-wage countries. Moreover, controlling for the endogeneity of both the sourcing decision and location by using instrument variable and DiD matching approach, the results seem also to suggest that firms that source inputs from high-wage countries benefited from doing so in terms of higher growth of productivity and export intensity. Firms that source inputs from low-wage countries, on the other hand, seem not to have experienced any significant impact on neither productivity nor export, not even three years after they started to source inputs from these countries. 相似文献

在我国现行政绩观和相关制度背景下,地方官员对城镇化发展会存在独特的“偏好”,并在城镇化进程中经常扮演重要的角色,因此地方官员是理解城镇化快速发展的重要一环。本文结合江西省地级市的经验数据,运用倍差法实证分析并定量提取市长和市委书记对辖区城镇化的净影响,发现地方官员对当前城镇化发展具有显著的正相关关系,进而论证了地方官员推动了城镇化发展的假说。 相似文献

Using propensity score matching (PSM) and the difference-in- difference (DID) approach, this paper explores the characteristics of listed Chinese firms that voluntarily disclose auditors' reports on internal control and the economic consequences. Using a sample of non-financial firms listed on the main boards of the Shanghai Stock Exchange and the Shenzhen Stock Exchange between 2006 and 2010, we find that firms are more likely to voluntarily disclose their auditors' reports on internal control if they have higher state ownership, lower managerial ownership, sanction records, audit committees, non-Big Four auditors as their auditors of annual financial reports, unqualified auditors' opinions on financial reports, less board independence, after controlling for firm size, liabilities, performance, and history. Moreover, as compared to a control group that exhibits similar characteristics, firms that voluntarily disclose auditors' reports on internal control are associated with positive earnings quality and negative cost of equity capital. 相似文献

农地转出行为对农民家庭的生计资本有何影响?——来自CFPS数据的验证 总被引:1,自引:0,他引:1
农地流转对农民收入的提升起着关键性作用,量化分析农地转出与生计资本之间的关系,有利于揭示现有土地流转政策的实际扶贫效果.在合理筛选控制变量和对农户生计资本水平进行测算基础上,基于中国家庭追踪调查(CFPS)两期全国整合样本的面板数据,运用倍差法(DID)及普通最小二乘法(OLS)实证检验了农地转出行为对农户生计资本所产生的影响.研究结果表明:农地转出对农户的自然和社会资本产生了显著负向影响,但却对其物质、金融和人力资本产生了显著的正向影响.各项生计资本的变化并非全部源于农地转出这一因素,还受到户主受教育程度、家庭规模及当地经济发展水平等其他变量的影响.进一步研究表明,农地转出规模越大,农户的物质和金融资本水平就会越高,其自然和社会资本水平下降得也越明显.农地转出家庭的生计发展在土地流转后尚存在一个适应的过程,还需要得到多方面的帮助以进一步提升家庭福利水平.基于上述发现,提出了培育、加强农地转出户生计资本,降低农户生计脆弱性,促进其生计可持续发展的对策建议. 相似文献

2009年我国实施的“摩托车下乡”政策拉动了农村居民对摩托车的消费。鉴于农村地区居民收入较低,摩托车的不同定价会影响销售吗?基于2007-2012年71家摩托车企业的面板数据,使用倍差法来评估“摩托车下乡”政策对不同定价的摩托车企业销售的影响差异性。研究发现,定价较低的摩托车企业在政策实施后销售量的增加大于定价较高的企业。这说明农村居民较为偏好满足基本需求的低定价产品。 相似文献
