基于模糊概念的可疑金融交易量化关联规则研究

从模糊集的基本理论入手,通过定义模糊概念软化属性域的划分边界,提出了一种新的基于模糊概念的量化关联规则方法.本方法克服了因划分区间而造成数据缺失的不足.最后通过将某市2004年的实际数据运用到建立的算法中,验证算法的有效性,为有效开展可疑金融交易识别提供了有益的参考.     

浅谈预算管理

预算管理是计划未来工作的过程,是工作计划的量化体现,同时也促进工作计划目标明确并且相互衔接。加强预算管理,对于规范公司业务流程,提高工作效率,增强可持续发展能力具有重要意义。     

再谈社会主义新农村建设

“中国农村象非洲”、“共产党还要我们穷多久”,这两种声音应该成为推进新农村建设的强大动力。从传统农业发展模式转变到大农业发展模式是新农村建设成败的关键;县级领导的作用与县域经济的现状,关系到能否完成新农村建设的重大任务;应将山区作为新农村建设的主战场,把发展农村合作组织作为工作重点,要处理好农村工作中的点面关系,要把尊重自然规律摆到主导位置。     

基于回归分析法的南京市耕地面积变化影响因素分析

首先主要运用Excel预测南京市耕地面积减少的趋势;其次,通过文献阅读确定影响南京市耕地面积变化的影响因素,进而利用统计学方法建立了耕地面积与各个影响因素之间的回归分析模型;然后对模型所得结果的相关性进行统计性分析,剔除可能具有相关性的影响因素;最后把对各影响因素在南京市耕地面积变化的过程中按所起的正、负相关影响进行归类分析。旨在为南京市在抑制耕地面积锐减现象对相关因素的控制上提供相关的参考依据。     

新冠肺炎疫情的经济影响分析：长期视角与短期应对*

本文从需求和供给两侧分析了此次新冠疫情对我国经济的短期和长期影响。在需求侧，基于理论分析和非典疫情对经济的影响特征，经济总需求会随着此次疫情的结束而在短期内快速得到恢复。但此次疫情也会加大总需求和居民收入增速的下行压力。在供给侧，疫情不仅会降低劳动力资源配置效率，加剧劳动力供需结构矛盾，同时也大幅降低了我国的资本投资，在缺乏有效干预措施下，很可能加剧我国资本投资和经济总体增速的短期下滑趋势。而基于理论分析，相应供给冲击也将对我国长期产出带来增长压力。基于疫情对我国经济需求侧和供给侧的影响分析，2020年要实现全面建成小康社会的经济目标需要实施改革力度更大、更为有效的财政和货币等支持政策。     

中国农业发展:多重困境与突破路径

作为新农村建设顺利推进的经济基础和逻辑起点,农业发展主要表现为农业增产基础上的农民增收.由于增产和增收、宏观战略和微观目标不一致,在理论和经验上表现出多重困境:主体形成困境、结构调整困境、谈判能力困境和生产效率困境,农业发展的基础不稳定也不牢靠.基于此,将家庭联产承包责任制转变为以家庭专业承包责任制为基本特征的组织创新将至关重要,这个组织演化过程是对农业发展多重困境的一个系统的、积极的回应.

Is regulatory adoption ceremonial? Evidence from lead director appointments

Research Summary: Regulatory bodies often wrestle with the thorny question of whether to mandate a governance practice or allow for organic adoption. While mandates afford rapid diffusion, we theorize that they also result in ceremonial adoptions. Leveraging a quasi‐natural experiment, we compare adoption outcomes for a governance practice—lead director adoption—that was mandated by the NYSE but not the NASDAQ. We find that NYSE firms are more likely than NASDAQ firms to have installed a lead director as a symbolic management tactic, so their lead directors are less effectual. We also find that transient institutional investors are deceived by this symbolic management, but dedicated institutional investors are not. Managerial Summary: Shareholders and analysts often desire to see companies introduce strict governance measures, such as proxy access and independent boards. Consequently, regulatory bodies often wrestle with the thorny issue of whether and when to mandate such practices for all companies. What they might not realize is that mandates may not work as well as they seem. Although more companies adopt reform under a mandate, they do so merely as a symbolic gesture. We look at one governance reform—appointing a lead director—finding that companies who introduce this reform as a result of a mandate appoint someone that is relatively toothless. We also find, though, that savvy investors are not actually fooled by this tactic and will trade out of firms that attempt such symbolic management.     

Catch Animal Spirits in Auction: Evidence from New Zealand Property Market

Following the animal spirits theory proposed by Akerlof and Shiller, this article contributes to behavior economics by investigating the possibility of using auction sales data to capture evidence of irrational exuberance in the housing market. Using the monthly percentages of residential property auction sales for Auckland, Wellington and Christchurch regions in New Zealand from 2006 to 2015, and the exuberance testing method proposed by Phillips, Shi and Yu, we find that animal spirits have been developing in the Auckland housing market since 2013, but not in other regions. When compared to the results based on price‐to‐rent ratios, auction sales provide more meaningful results for identifying market‐wide irrational exuberance at an early stage. The causality test on price‐to‐rent ratios and auction sales volume shows that asset prices and animal spirits influence each other in the short run. In the long run, prices have significant effect on animal spirits, but not vice versa.
