改革开放以来我国三农问题关注重点变化及其演进逻辑

本文从政策法规、主流期刊及新闻媒体三层面梳理了改革开放以来我国三农问题关注重点的变化,从国家经济实力和城乡关系演变的视角剖析这种变化背后的内在逻辑,讨论了未来我国三农问题研究需要关注的重点。研究表明,三农问题关注重点由改革开放初期的温饱问题,到市场经济运行期的市场经济体制问题,再到工业反哺农业期的农村小康问题,最后到推进农业现代化阶段的发展问题。不同时期关注重点有所变化的一个重要原因,是城乡关系在不同时期所呈现出的不同矛盾。对未来三农的关注点应该以乡村的视角,从科技、人才、文化、生态和治理等方面进行乡村振兴。

农村中小金融机构资本监管与盈利能力——基于风险承担与资产质量的中介效应

鉴于农村中小金融机构整体盈利性不足,考虑银行资本对利润侵蚀和创造的作用路径,本文构建资本监管影响银行盈利能力的计量模型,选取全国94家农村中小银行2014—2019年面板数据进行实证研究。结果表明,农村中小金融机构资本监管对其盈利能力具有显著影响,较高的资本缓冲降低了银行的经营绩效。村镇银行的资本储备抑制了利润增长,其风险承担存在主要中介效应;农商行则具有异质性,资本储备的利润创造效应大于侵蚀效应,其资产质量存在部分中介效应。此外,资本监管对农村中小银行盈利性的影响具有经营地域、资产规模和支农服务的异质性。
