Institutional dynamics and access to non-farm employment in rural China, 1950–1996

This article examines non-farm employment in the context of Chinese rural institutional change, based on evidence from discrete-time logistic models for event history analysis using the Life History and Social Change survey. We find the transition to non-farm sector rose rapidly during the Great Leap Forward and market reform, while the Cultural Revolution saw it reach the lowest ebb. While male advantage prevailed exclusively during the Cultural Revolution and early marketization, education possessed a stable positive effect in all historical periods. Although the returns to different kinds of political capital vary along with institutional dynamics, intergenerational reproduction was greatly reduced after the Cultural Revolution.

金融周期、行业技术周期与经济结构优化

本文首先采用马尔科夫区制转移模型测算金融周期和12类行业的技术投入周期,进而采用交叉谱分析法和OLS法分析金融周期对行业技术周期的影响,结果发现:不同金融变量的周期具有异步性,各行业的技术投入周期具有明显差别;不同金融变量周期与行业技术投入周期之间存在不同的数量关联性,对不同的行业技术投入具有不同的影响作用;在繁荣阶段,金融市场和银行对各行业的技术投入都具有正向推动作用,但金融市场对高密度创新行业技术投入的推动作用更为显著,银行对低密度稳定行业技术投入的推动作用更为显著;在紧缩阶段,金融市场对高密度创新行业技术投入的紧缩效应更为剧烈,银行却对低密度稳定行业的技术投资下行起到缓解作用。根据这些事实和规律,可以引导利用各金融变量对具有发展前景的行业强化技术投资助推作用,提升经济结构优化效率。

Mandatory IFRS adoption and management forecasts: The impact of enforcement changes

We examine how concurrent enforcement changes affect the positive relationship between mandatory IFRS adoption and firms’ voluntary disclosure. We show that the increase in the issuance of management forecasts after IFRS adoption is smaller for firms from IFRS-mandating countries with concurrent enforcement changes than for those from countries without such changes. We find no difference in the increase of forecast informativeness between firms from IFRS-mandating countries without concurrent enforcement changes and firms from non-IFRS-mandating countries; however, firms domiciled in IFRS-mandating countries with concurrent enforcement changes exhibit a significantly smaller increase in forecast informativeness. Our findings suggest that better IFRS enforcement distinctly weakens (strengthens) the positive effect of IFRS adoption on voluntary (mandatory) disclosure.     

POI数据辅助下的泸州市城市地块用地类型现状快速判断与验证

［目的］土地利用规划和城市规划的用地地块，在实际使用过程中，都会不同程度与规划用途产生差异，如何把握规划的实施程度是土地管理中的一个重要问题。［方法］在大数据时代的背景下，通过对网络大数据可以真实地反映城市地块的真实使用状况。研究采用OSM（Open Street Map），对研究区进行城市地块的划分，形成街区尺度的城市地块。采用POI（Point of Interest）数据，建立了POI分类与城市用地分类的映射关系，计算了不同类型的POI数据的频数密度和类型比例，形成基于POI的城市地块用地类型识别方法，对研究区的城市地块进行土地利用现状识别。识别结果与第二次土地调查分类结果进行对比，验证方法的可行性。［结果］从泸州市的实证结果看，基于POI数据的城市地块识别结果与基于地籍数据的城市地块识别结果存在很大的差别。地籍数据主要是表针城市地块中不同实体的土地利用状况，两种数据采集的标准和表达的意义都不同，因此造成结果存在较大的差异性。［结论］研究认为，POI点有准确的空间位置信息和丰富的属性信息，主要是表征城市地块中不同实体的真实使用状况，可以较准确地判定快速发展的城市进程中的城市用地类型，能较为真实反映城市地块的现实使用状况，但也要注意POI数据在实际应用中存在的缺陷和不足。     

Weak‐instrument robust inference for two‐sample instrumental variables regression

Instrumental variable (IV) methods for regression are well established. More recently, methods have been developed for statistical inference when the instruments are weakly correlated with the endogenous regressor, so that estimators are biased and no longer asymptotically normally distributed. This paper extends such inference to the case where two separate samples are used to implement instrumental variables estimation. We also relax the restrictive assumptions of homoskedastic error structure and equal moments of exogenous covariates across two samples commonly employed in the two‐sample IV literature for strong IV inference. Monte Carlo experiments show good size properties of the proposed tests regardless of the strength of the instruments. We apply the proposed methods to two seminal empirical studies that adopt the two‐sample IV framework.     

乡村振兴背景下安徽省农村经济与人居环境协调度研究

在乡村振兴战略背景下,应关注农村内部各系统之间的相互协调,以期实现乡村整体水平的优化发展.以安徽省为研究对象,建立农村经济与人居环境发展水平的指标评价体系,运用熵值赋权法、耦合协调模型,计算各市农村经济与人居环境发展水平的综合指数以及二者的协调度.实证结果表明:安徽省农村经济与人居环境水平具有明显的区域差异性,总体协调度相对偏低.因此,应进行不同产业的深度融合,树立绿色引领乡村振兴的理念,健全农村公共设施的投资机制等.     

Remaking Shanghai: New Divisions in an Expanding Metropolis

This study of Shanghai analyzes the city's emerging patterns of residential settlement in 2010. Most previous research on China focused on central city patterns, but by 2010 urban development in major metropolitan areas was taking place predominantly in the suburbs. The analysis re‐examines and extends previous studies of the level of segregation by various key population characteristics, showing that the highest segregation is found in the suburban ring, where original villager residents are now joined by an influx of migrants from other regions and by intracity movers. We probe the sources of the segregation pattern in multivariate analyses at two scales—an innovative analysis at the level of individuals that shows how people's citizenship status, occupation and education affect the type of housing that they are able to live in, and jointly contribute to their location in the metropolitan area. We show that the patterns attributable to the market reform period mostly did not supplant the socialist urban structure, but rather used it as its foundation. Segregation today can be attributed less to current class inequality than to state policies in the distant and recent past that have determined when, where and for whom housing is built.     

创业失败经验对连续创业意愿的影响——创业失败学习与市场动荡性的作用

基于经验学习理论，探究创业失败经验如何通过创业失败学习影响创业者连续创业意愿，以及市场动荡性的调节作用。对176位有失败经历的创业者进行问卷调查，结果表明：创业失败经验对创业失败学习和连续创业意愿均有显著正向影响；创业失败学习在创业失败经验与连续创业意愿关系间起中介作用；市场动荡性负向调节创业失败学习与连续创业意愿的关系，即市场动荡性越高，创业失败学习与连续创业意愿间的关系越弱。研究结论对于拓展创业失败经验与连续创业意愿研究、帮助创业者从失败中复原，以及激励连续创业具有重要理论价值和实践意义。
