Breakthroughs on Fundamental Issues of Socialist Political Economy in China’s Economic Reform

How to effectively integrate the basic economic system of the primary stage of socialism in which public ownership is the dominant and diverse economic sectors develop side by side with a resource allocation model in which the market plays a decisive role is a fundamental issue in building a socialist political economy with Chinese characteristics. Western bourgeois economics and the traditional understanding of Marxist classical writers reject the possibility of such integration. In the transitional countries of Central and Eastern Europe, the practice and theoretical exploration of combining the two ended by abandoning public ownership. The fundamental feature of socialist economic reform practice with Chinese characteristics is to uphold their organic unity. This approach has already achieved great progress but at the same time is confronting a series of new problems.     

高校学生党员答辩机制的创新研究

在高校学生党员培养全过程中建立并完善答辩制度,对于进一步提高学生党员综合素质、加强基层党组织建设、增强高校学生党员发展工作的科学性和和公信度均具有重要意义。完善层次分明、以人为本、与时俱进的答辩内容,是提高学生党员教育、培养、考察和监督实效的关键。应从完善答辩程序、建立分层培养、突出过程评价、加大监督力度这四个方面对高校学生党员答辩机制加以创新研究,不断推进高校学生党建工作。     

股市危机中股指期货应该限制交易吗——基于2015年股市危机的实证分析

利用上证50、沪深300和中证500股指期货合约及其相应指数的高频数据,克服了传统BEKK和DCC模型的不足,通过建立VECM-DCC-VARMA-AGARCH模型考察股市危机期间中国股指期货市场与股票市场之间的信息传导关系与风险传染效应。研究结果表明,股市危机期间股指期货具有很强的价格引导和风险传染效应,股指期货的持续波动加剧了股票市场的进一步波动。因此,提出风险传染效应与市值规模相关、非对称效应和非预期冲击效应与市值规模负相关、波动的风险传染效应与市值规模正相关。危机时期,应抑制股指期货市场上的过度投机,对股指期货采取限制开仓、提高交易保证金和交易手续费都是正确和切实可行的措施。建议监管当局健全股指期货和股票市场交易制度。     

货币政策的债券市场传导机制——对利率的预期渠道

从对利率预期的角度探讨债券市场在货币政策传导到实体经济过程中的作用十分重要,将该传导机制细分为两个阶段:货币政策对债券市场的影响和债券市场对实体经济的影响,经理论建模和实证发现:两阶段的传导都非常有效,货币政策的债券市场传导机制确实存在。将两阶段结合起来看债券市场的传导效果,发现存贷款基准利率、法定存款准备金率及公开市场操作利率等货币政策工具能够对经济增长和通胀水平产生显著影响。实证结果还表明:在货币政策的实施过程中应当充分挖掘收益率曲线中包含的信息;央行的货币政策遵循了逆周期的原则,很好地熨平了经济的异常波动;应当提高货币政策体制的可信度和透明度,形成稳定的长期利率目标。     

Perceptions of grandparents who provide auxiliary care: value transmission and child‐rearing practices

A grounded theory qualitative study was developed to explore how grandparents perceive their role as socializing agents. Forty‐two grandparents with grandchildren aged from 6 to 12 years old participated in this study. Data were collected through focus groups, which were conducted until reaching data saturation and analyzed using the constant comparative method. Four general conclusions emerged from the study: (i) grandparents recognized the importance of getting involved in the socialization of grandchildren as supporters of parents' socializing role, and the need to adapt to social changes; (ii) they emphasized traditional value that were perceived in decline, and combination of warmth and involvement were considered the best way to help grandchildren internalize values; (iii) interaction with grandchildren helped grandparents to feel active and useful, increased their life purpose and gave them a second chance to enjoy what they could not with their own children; and (iv) grandparents also accused burden and role ambiguity. These results show the importance of developing family policies that recognize grandparents' socializing role. Also, interventions that promote strategies that enable grandparents to perform their role more successfully and to cope with possible family conflicts should be developed.     

基于自增强机制的矿区产业共生系统自稔性风险研究

矿区产业共生系统作为一种极具特色的产业组织形式，对区域经济的发展具有重要的驱动作用，已成为各国发展矿区经济的重要政策工具。自增强机制可以使矿区产业共生系统实现规模递增，带来协同效应和竞争优势。但同时也带来系统内企业惰性增加和适应性减弱，在外部环境发生变化时，在自增强机制的作用下，矿区产业共生系统内企业容易走上无效率的状态。因为系统内企业间信息同质性越高，系统的锁定效应和路径依赖就越明显。     

上海生态文明建设的激励和约束机制研究

生态文明建设是一项系统工程,需要通过整体推进,构筑规划、建设、管理、技术、产业、社会和合作协同发展的综合体系。未来上海应以建立和完善市场机制为核心,以法律机制为前提,以政府监管机制为保障,以能力建设机制为基础,以社会参与机制为监督,按照"引逼结合、多方合力、突出重点、先行先试"的原则,加快上海生态文明建设机制创新。主要途径有:完善碳排放交易试点,建立长效市场机制;推进分布式能源应用,提高清洁能源比重;加快新能源汽车推广,优化交通能源结构;培育发展再制造产业,推广先进制造理念。     

策略延迟下众筹项目的定价和激励决策

本文研究了投资者的策略延迟行为对众筹项目的定价以及激励决策的影响。策略延迟是指投资者在投资过程中自动按照估值在相应阶段投资，并且部分投资者会刻意延迟投资来搭便车的行为。本文采用了一个两阶段模型来刻画投资者的投资行为，并进一步对比序列到来模式（投资者没有策略延迟）与同时到来模式（投资者有策略延迟）中的贝叶斯均衡。研究结果表明，当发起人采用价格激励的方式提高成功率时，投资者的策略延迟行为可能会影响最优的激励策略。当存在固定目标约束时，如果投资者没有策略延迟行为，发起人应该激励前期投资者，通过弥补他们等待成本的方式提高成功率；反之如果投资者出现策略延迟行为，对项目估值较高的投资者会自动在前期投资并且愿意承受更高的价格，此时发起人应该反过来激励后期投资者。当不存在目标约束时，不论投资者是否有策略延迟行为，发起人都应该始终激励前期投资者以获得更高的成功率以及期望收益。
