Residential segregation and educational attainment of children from regional migrant families in China

This paper studies the residential segregation effects on educational attainment of children from regional migrant families in China. We find that if migrant families live in segregated communities with fewer local residents, the school dropout rate of the children living with their parents in the host cities is higher and their high school enrollment rate is lower. We employ a unique set of nationwide survey data of regional migrants in China in 2012 and 2013 that comprises more than 150,000 individuals in each year. We first use the ratio of migrants over the total population residing in a community to measure segregation. When the ratio increases by 10%, the school dropout rate of migrant children increases by 4.7% from the mean value. Secondly, we identify segregation from the housing type of the migrant family. When they reside in the dorms provided by their employers or in the workplace, they will also be surrounded by many migrant colleagues. We find that living in such places increases the “not‐going‐to‐high‐school rate” of migrant children by 35% from the mean value. Our subsample analysis indicates that the segregation effects only exist in the samples of male migrant children and rural hukou families.     

Payday loans and consumer financial health

The annualized interest rate for a payday loan often exceeds 10 times that of a typical credit card, yet this market grew immensely in the 1990s and 2000s, elevating concerns about the risk payday loans pose to consumers and whether payday lenders target minority neighborhoods. This paper employs individual credit record data, and Census data on payday lender store locations, to assess these concerns. Taking advantage of several state law changes since 2006 and, following previous work, within-state-year differences in access arising from proximity to states that allow payday loans, I find little to no effect of payday loans on credit scores, new delinquencies, or the likelihood of overdrawing credit lines. The analysis also indicates that neighborhood racial composition has little influence on payday lender store locations conditional on income, wealth and demographic characteristics.     

Potential Spatial Labor and Human Capital Mobility in China: Evidence from College Admissions Under the National College Entrance Examination System

Abstract:

Higher education in China plays an important role in promoting labor and human capital mobility. In this paper, I empirically address the issue of regional disparities, college admissions under the National College Entrance Examination (CEE) system, and potential interregional labor and human capital mobility in China. The results show that examinees from western provinces have a strong preference for coastal universities, compared with examinees from central provinces. College admissions in China then seem to have a stronger effect on potential labor and human capital movement from the western to the coastal regions than from the central to the coastal regions.     

碳排放约束视角下产业智能化对区域经济差距的影响研究

本文利用2003~2019年中国省级面板数据,从碳排放约束视角出发,实证考察了产业智能化对区域经济差距影响的差异性和产业智能化影响区域经济差距的机制。研究表明,产业智能化对缩小全国、东、中和西部地区省域间经济差距具有显著的正向效应;进一步考虑碳排放约束,发现碳排放约束正向调节了产业智能化对区域经济差距的正向效应,西部地区由于自身产业结构和区位因素,抑制了产业智能化对区域经济差距的正向效应;最后,对产业结构升级的两个子维度在产业智能化和区域经济差距间的中介效应检验,发现产业结构升级的中介效应存在,且主要是通过产业结构高级化实现,产业结构合理化发挥的作用较小。     

数字经济对区域经济高质量发展的影响研究

推动数字经济发展,是我国在当下推动经济转型,促进高质量发展的重要战略。本文基于2012~2019年省级面板数据,构建双向固定效应模型,运用基准回归、异质性检验和分位数回归的方法进行实证研究发现,数字经济助推经济高质量发展的同时还存在地区差异,对西部影响最大,中部影响最小,而数字经济的发展水平又受到产业结构、技术创新等因素影响。因此,本文针对不同地区差异分别提出建议,从而促进持续更新发展理念,以创新驱动发展,优化产业结构为数字经济提供良好环境,以期推动数字经济建设发展。     

国际生产分割视角下的中国双边贸易平衡--以东亚经济体为例

为了解释中国近年来对东亚经济体贸易逆差持续地增加的现象,文章在国际生产分割背景下,分别基于总体、国家（地区）和行业视角,对1992—2012年中国与东亚8个经济体间的零部件贸易面板数据进行实证分析。结果表明：中国作为东亚国际生产网络中的枢纽,从日韩等东亚经济体进口零部件会显著扩大中国对东亚经济体的贸易逆差,其中以ICT行业最为典型;生产分割效应弱化了汇率对双边贸易平衡的影响。只要中国在国际生产分割中所扮演的角色不变,中国对外贸易总体顺差和区域性逆差的局面将会持续存在。     

服务贸易开放与我国居民收入差距——基于不同组成部分的比较研究

我国居民的收入差距尤其是城乡收入差距,自从改革开放以来在不断扩大,与此同时服务贸易开放度也在不断扩大。利用我国1982—2010年的年度数据,通过引入多个控制变量,采用多元回归模型对不同服务贸易组成部分对我国城乡居民收入差距的影响进行实证检验,结果表明旅游服务、其他商业服务贸易具有缩小我国城乡居民收入差距的效应,而交通运输服务具有扩大我国城乡居民收入差距的效应。今后应进一步通过简化审批、减少垄断来扩大服务业的开放,大力发展服务贸易来抵消部分货物贸易对城乡居民收入差距产生的不利影响。     

二战后马克思主义经济学面临的现实性挑战及其回应

时代的发展与变迁对马克思主义经济学提出了新的问题和挑战,对此中外马克思主义经济学者在理论上进行了大量的有价值的研究和探索。从科技革命的推动与资本主义的历史地位、市场经济体制的建立与社会主义的发展、西方经济思潮的冲击与马克思主义经济学主流地位的坚守四个方面,梳理了二战以来中外马克思主义经济学者的研究成果,发现马克思主义经济学的生命力与科学性正是源于在实践中的丰富和发展,因此,坚持马克思主义经济学在中国的指导地位,首先必须在新的时代条件下,与时俱进,创新和发展马克思主义经济学。     

我国工业化、城市化对能源消费强度的动态效应与区域差异——基于动态面板数据模型的系统广义矩(SYS-GMM)分析方法

基于2002-2012年中国的省际面板数据,将能源消费强度分为低、中和高三个层次,运用动态面板数据模型的系统广义矩(SYS-GMM)分析方法,对工业化、城市化对中国能源消费强度的动态效应与区域差异进行了实证分析。研究结果表明,工业化、城市化水平提高均会导致地区间能源消费强度的增加,但城市化对低能源消费强度区域的影响并不显著,而对高能源消费强度区域的影响却十分明显。此外,上一期的能源消费强度、地区经济发展水平、能源价格和技术创新等均对中国能源消费强度产生不同的影响,而且中国存在技术创新的反弹性效应且能源价格对技术创新有诱致性作用。     

交易成本、禀赋效应与国有股权转让定价——兼论国有企业混合所有制改革的新思路

国有企业混合所有制改革是积极发展混合所有制经济的关键,完善的定价机制有助于推进国有企业混合所有制改革。国有股转让过程中存在大量的交易成本,扭曲了定价体系。基于科斯定理,可以发现,明晰产权是优化定价体系有效途径。但是,禀赋效应的存在,使得科斯定理无法完全解决国有股转让定价问题。对此,需要采取市场和非市场的政策组合,以此来完善国有股转让定价机制,推进国有企业混合所有制改革。
