股权金融市场、增长方式选择与平衡增长：传统与新兴部门视角*

为探究股权金融市场对增长方式选择和平衡增长的影响，本文基于传统与新兴部门的差异，构建动态理论模型并利用“Simulink”技术进行数值模拟分析。理论分析发现股权金融市场效率对平衡增长具有增长效应且存在门槛条件，效率高于门槛值时股权金融市场发展将提高平衡增长率和创新贡献率。总体上，发展股权金融市场将促进我国平衡增长和增长方式转变，但东、西部地区存在差异，发展股权市场可以加快东部地区创新型增长而对西部地区没有显著作用。     

“十四五”战略性新兴产业发展的思考

过去10年间,我国战略性新兴产业从小到大、从弱到优,有力地支撑了新旧动能接续转换、供给侧结构性改革、创新型国家建设、区域协调发展和全面开放迈向新台阶。未来5年,应积极引导企业增加基础研究和应用研究投入,集中资源推动重点领域关键核心技术突破,最大限度利用好国内国外两个市场空间,着力构建国际一流的创新创业基础设施,继续做好有利于集聚技术、资金、人才等创新要素的软环境建设。     

FAMILY PLANNING AND WOMEN'S EDUCATIONAL ATTAINMENT: EVIDENCE FROM THE ONE‐CHILD POLICY

This paper exploits China's one‐child policy (OCP) to study the relationship between fertility and educational attainment of the mothers of China's “sibling‐less generation.” I take two difference‐in‐differences approaches to estimate the OCP's effect on women's education: one compares gender difference among the ethnic majority group and the other compares ethnicity differences between ethnic majority women and ethnic minority women. I also explore the heterogeneity of the policy's effects by parent's status at the Communist Party. I find that the OCP has a positive and significant effect on women's education and explains about half of the increase in educational attainment for women born between 1960 and 1980. Their increased educational attainment associates with delayed entry into first marriage, delayed entry to parenthood and increased labor supply. (JEL I20, J13, J16, J18)     

产业融合对中国装备制造业创新效率的影响:结构嵌入的调节作用

从理论和实证两个方面探讨了产业融合对中国装备制造业创新效率的影响，以及网络中心性和网络异质性对二者关系的调节作用。基于2006—2015年省际装备制造7个子行业面板数据，采用ISCNFI指数测度模型和基于产出距离函数的超越对数前沿分析方法，分别测度装备制造业产业融合程度及创新效率变化情况，进而利用面板回归模型对理论假设进行实证检验。结果显示：产业融合程度与中国装备制造业创新效率存在倒“U”型曲线关系，即随着产业融合程度提升，中国装备制造业创新效率呈现出先上升后下降的变化趋势；网络中心性强化了产业融合对装备制造业创新效率的提升作用，而网络异质性削弱了产业融合对装备制造业创新效率的提升作用。     

Thriving and career outcomes: The roles of achievement orientation and resilience

This research investigated how and under what conditions thriving at work affects career attitudes and behaviors. Using an experimental design (n = 174), Study 1 found that the effects of thriving on career satisfaction, career commitment, and career engagement were mediated by career resilience. The positive effect of thriving on career resilience and the resilience‐mediated effects of thriving on career satisfaction, commitment, and engagement were stronger when achievement orientation was higher. Study 2 verified these findings with a survey of another sample of 296 employees. These studies offer important insights for human resource managers and career consultants or practitioners regarding what may enhance employees' career outcomes. Our findings imply that thriving‐enabling practices might be beneficial among highly achievement‐oriented employees.     

Factors affecting agricultural land transfer-in in China: a semiparametric analysis

We use interview survey data collected randomly from 2677 farm households in nine provinces of China to understand the role of demographic, economic, land, and village characteristics on agricultural land transfer-in by farmers. Results show that variables such as borrowing from informal sources, household labour availability, percentage of total income from agricultural sources, and the household with village cadre have significant positive effects on land transfer-in. Low economic development and low transportation network availability in a county reduces land transfer-in. We also find that two variables (land holding and land idling) should be entered into the model nonparametrically. Land holding and land idling have U- and L-shaped impacts on land transfer-in, respectively. Land transfer-in has endowment equilibrium and provides Chinese households more opportunities to earn agricultural income, thereby reducing rural poverty.     

盘锦30万吨原油码头超硬地层沉桩施工技术

在标准贯入度达到60击以上的较厚极密实砂土地层沉桩时,受船机设备性能限制通常会采用冲水沉桩等施工工艺,而配备D-180柴油锤的"葛飞腾2"超大型打桩船合理利用船机性能,采用动态控制锤击过程的施工方法可以直接穿透此类地层,效果良好。     

应用型本科现场管理课程教学内容研究

《现场管理》是很多高校管理专业、机械专业等本科阶段的必修课程。该课程内容涉及大量与生产实践密切联系的内容，且具有较强的行业专业性。为增强课程的普遍适用性，文中提出将教学目标主要围绕在“观察能力”的塑造及“思考维度”构建这两方面，并在此目标指导下，系统设计了该课程的教学内容模块。     

基于泰勒规则的人民币套息交易

本文利用泰勒规则对汇率改革以来的人民币汇率进行预测,基于各种预测模型构建模拟的人民币/美元套息交易策略,并依据风险调整收益、最大回撤率和收益偏度等指标来考察各交易策略的获利能力.实证结果表明:基于人民币的套息交易可以获得明显的收益,而基于泰勒规则预测的套息交易收益更佳,它超越了作为比较基准的随机游走模型的表现.考虑了经济基本面中不可直接观测的时变因子的影响作用后,套息交易的收益改善程度尤为明显.这为比较和权衡相关汇率模型的预测能力提供了新的视角.此外,对比在岸市场和离岸市场人民币套息交易的收益表现,说明在人民币利率市场化进程中健全金融监管和对资本账户采取适当管制措施是必要的.     

水泥土复合管桩浅析

水泥土复合管桩是由高喷搅拌法形成的水泥土桩与同心植入的预应力管桩复合形成的获得国家专利的新型复合桩型.水泥土复合管桩不仅桩身材料强度高,还兼有侧阻力大的优点.既可作为基桩使用,也可将其用于复合地基.水泥土复合管桩充分利用原土,且施工时无噪音和污染,经济、环保,适用于粉土、粘性土、素填土、砂土等土层,特别适合软土地基.相比起纯粹的水泥土桩和预应力管桩,适用范围更广,发展前景更广阔,属于绿色建筑基础.
