殷德生：中国式经济增长与结构转型的规律性成果及理论体系
摘要：改革开放40多年来，我们用几十年的时间走完了发达国家几百年走过的发展历程，创造了“世所罕见的经济快速发展奇迹”，书写了“人类反贫困史上的中国奇迹”。中国式赶超增长和结构转型是一个庞大的叙事，蕴藏着理论创造的巨大动力、活力、潜力，尤其是对发展经济学的重塑和创新。本报告基于中国式赶超增长与结构转型的特征事实，提炼和总结其中的规律性成果和原创性理论，既展现本土特征又具有与西方发展经济学相洽的学理，揭示中国式赶超增长和结构转型的动力源泉，将发展社会生产力的“世界性”和我国社会主义基本经济制度等“本土性”结合起来构建中国式发展经济学。
何超：再论信用与货币
摘要：Gu、Mattesini和Wright(2016)指出在货币均衡里，信用(即延期付款给卖方)的变化不影响经济活动。 我们发现如果在他们的模型中同时允许货币信用(即从第三方借款)，则两种信用的变化都会影响经济活动。并且，在一定条件下两种信用状况的变化会引起货币价值反方向的变动。换言之，货币可能成为金融加速器或者缓冲器。我们的结果表明了在理论模型中刻画货币以及区分不同类型的信用的重要性。
金培振：城市异质性、制度供给与创新质量
摘要：基于城市异质性视角分析制度供给如何影响中国城市的实质性、可持续和协同式创新。研究发现:制度供给导致不同城市的高质量专利在数量与结构方面呈现空间分化趋势,其作用于创新质量的空间溢出方向和溢出距离也受城市异质性影响而表现各异。创新要素培育与配置是制度供给影响城市创新质量的重要机制。
李蔚：Managing China’s Stock Markets: The Economics of the National Team
摘要：We exploit China’s great stock market crash in 2015 to study the effects of government stock purchases. The Chinese government purchased stocks to stabilize the market through state-owned financial institutions collectively called the “National Team”. We find that the intervention led to reduced trading volume, volatility, and price informativeness. These impacts mainly come from the disclosure of the government portfolio. These results are consistent with the heterogeneous.

钟粤俊：空间、结构与增长——人口和土地再配置效应的空间均衡分析
摘要：中国可以通过城市化和土地供应政策调整优化产业结构，进而促进服务业发展和经济增长。本文构建包含两部门和“1+N”地区的空间一般均衡模型，研究要素的空间配置如何影响经济结构转型和增长。由于收入效应和规模效应，大城市发展服务业的比较优势更强，我们通过量化分析发现，畅通劳动力流动，促进人口向大城市高效集聚，可以使服务业占总产出之比上升2.5-3.5个百分点，城市间收入差距缩小14%，总产出上升10%，社会福利提高7.4%。其次，增加大城市土地供应可使服务业进一步发展，总产出和社会福利增加。进一步地，同时增加大城市土地供应和畅通劳动力流动，可使服务业占比上升3-4个百分点，总产出增加12%，社会福利增加9%。本文的政策含义是，解决区域资源配置的体制性、结构性问题，能产生巨大的制度红利，更好发挥国内大循环、国内国际双循环相互促进的作用，推动经济发展。
龙翠红：The effect of fertility on parental financial assets diversity: another disparity led by hukou system
摘要：From the perspective of urban-rural disparity driven by Chinese household registration system (hukou system), this article explores how the number of children affects parental financial assets diversity by exploiting the one-child policy enacted in 1979 in mainland China. The strict birth-controlling policy created conspicuous kink with relatively small jump in the probability of having only one child relative to multiple children across the birth cohort of individuals’ first child. Employing regression probability jump and kink (RPJK) design, the results demonstrate that having only one child instead of multiple children could significantly enhance non-agricultural hukou holders’ financial assets diversity, in comparison, there isn’t any significant effect of decreased fertility on agricultural hukou holders’ financial assets portfolio. Through mechanism analysis, we found that having only one child could raise the probability of using the Internet, and improve offspring’s educational attainments, further enrich non-agricultural parents’ financial assets. This paper also has important implications, the continuously declined fertility slackened Chinese households’ temporal and pecuniary constraint to some extent. Theoretically, the extra time and money related budget would lead to more financial market participation. While, the promotion effect of lower fertility on residents’ financial assets diversity only exists in non-agricultural households, further entrenching the urban-rural inequality. Chinese authority should neutralize the role of allocating socioeconomic resources hukou system has long colonized by broadening agricultural hukou holders’ access to social securities and economic opportunities.
姚羽欣：The Intergenerational Effects of Parental Early Life Hunger Experience on Children Outcomes: Evidence from China
摘要：This paper investigates the effect of parental early life hunger experience on adult children’s completed education, self-reported health, and labor market performance. Using detailed life-history data from China, we find that hunger experience at maternal early childhood and paternal teenage has significant negative impact on adult children’s years of education, while parental hunger experience at school-age has significant negative impact on adult children’s self-reported health. Our findings add evidence to the “international transmission” of negative effects of early life deprivation on children’s education and health, which indicates that early-life nutrition intervention, especially at certain “critical period” can have an intergenerational multiplier effect.
郭白滢：基金家族共同持股行为及其影响研究
摘要：共同持股是基金家族普遍采取的投资策略，对于基金家族行为方式、风险收益以及市场绩效能够产生重要影响。本文基于基金共同持股关系网络，采用 QAP 分析方法，研究基金家族共同持股的影响因素以及共同持股对于股票市场价格的影响。研究结果表明：（ 1）我国的基金家族成员倾向于共同持有股票，即同一家族内基金股票配置的相似程度高于不同家族的基金；（ 2）大基金家族内部基金之间普遍具有更高的持股重合度，且持股重合度具有顺周期的特征；（ 3）股票的动量效应与持股基金家族数量负相关，即被更多基金家族持有导致股票的动量效应的下降。本文的研究丰富了基金家族共同持股行为及其影响的研究，为基金市场监管与股票市场预测提供了经验参考。
