技术嵌入与数字化商业模式创新——基于飞贷金融科技的案例研究

随着数字技术的快速发展,数字化商业模式创新成为企业竞争的利器,而技术嵌入是企业内化数字技术支撑数字化商业模式创新的重要策略.本文基于飞贷金融科技的创新实践开展纵向案例研究,探究技术嵌入对数字化商业模式创新的影响.研究发现:技术嵌入包含技术整合和技术开发,两种策略在企业发展过程中经历了不同形式的演变.其中,拼凑式技术整合更有利于商业模式要素创新,而协奏式技术整合更有利于商业模式架构创新.利用式技术开发更有利于商业模式渐进创新,而探索式技术开发更有利于商业模式颠覆创新.最终,案例企业的数字化商业模式呈现出一条"流程信息化→渠道平台化→产品数字化→技术产品化"的进阶式演化路径,数字化程度相应呈现"类抛物线"的演变规律.本研究丰富了数字化商业模式创新的相关理论,并为科技型企业构建数字化商业模式提供了实践启示.     

近代巴蜀诗人李士棻生卒年及别号考略

近代巴蜀诗人李士棻曾被曾国藩誉为“太白醉魂”，为曾府门下“四川三李”之一，其诗作有浓郁的巴蜀文化特色。然李氏仕宦不显，长期以来学界对其关注不足，学界近年不多的相关研究，多围绕国内所存的文献，对其诗歌创作进行艺术分析，对诗人的生平介绍多简单略过，没有严谨的考证，目前仍然很有争议。通过搜罗国内外现存典籍，综合目前所见李士棻本人著述，辅以晚清近代重要报刊《申报》和与李氏有交往的朝鲜文人文献，考证其生卒年及别号，冀为今后的相关研究解决基础问题。     

要素拼凑、双元创业学习与返乡创业者创业经验优化 ——基于特定间接效果模型的评估

利用253位返乡创业者的调查数据,采用阶层回归分析、特定间接效果模型评估等方法,分析要素拼凑、双元创业学习对返乡创业者创业经验优化的影响机理.结果表明:要素拼凑对返乡创业者创业经验优化和双元创业学习均有显著正向影响;利用式学习和探索式学习在返乡创业者要素拼凑与创业经验优化之间均起中介作用,且利用式学习的中介影响力更强.因此,为推动返乡创业企业高质量发展,建议返乡创业者有效利用先前经验优势返乡创业,并因地制宜积极开展要素资源拼凑活动;同时,在创办企业初期,返乡创业者可侧重利用式学习持续优化创业经验,而在创业成长期及之后,则应注重利用式学习与探索式学习的相机结合.     

区块链应用下生态农产品供应链优化

利用博弈模型，对生态农产品供应链内部契约合作稳定情况进行研究，并就区块链技术如何保障生态农产品供应链稳定运行进行分析。分析认为：生态农产品供应链稳定运行情况受到市场风险制约，区块链技术能通过改善生态农产品供应链内部信息不对称现象，增加生态农产品供应链内部交易节省成本并提高主体违约成本，同时增加生态农产品供应链主体长期合作得益及协调主体合作，从而保障生态农产品供应链稳定运行。在此基础上，结合区块链技术特征对区块链技术应用下生态农产品供应链结构设计进行了探讨并对部分可能出现的问题进行了讨论。     

新生代乡村教师的离职意向与政策改进

新生代乡村教师是乡村教育的新生力量和未来的中流砥柱，他们能否安心留在乡村学校从教，关系着乡村教育的可持续发展。为解决乡村教师"留不住"的问题，国务院办公厅于2015年6月发布《乡村教师支持计划（2015-2020年）》，从经济待遇、社会地位、专业发展等方面着手，提出了具体措施。但是通过实证研究发现：当前新生代乡村教师的离职意向仍然普遍存在，尤其是其中的男教师和工作在乡村小学的教师；新时代乡村教师的离职意向，受经济待遇、社会地位、专业发展、个人偏好、乡村文化适应性、家庭和学校支持度、教师教育满意度等多方面因素的影响，其中个人偏好和乡村文化适应性是最主要的影响因素。因此，为了更好地留住新生代乡村教师，仍需在"乡村教师支持计划"现有政策支持的基础上，进一步补充和完善相关的政策措施：（1）重视乡村教师招聘和管理过程中对个人偏好的考察与培育；（2）积极帮助新生代乡村教师适应乡村文化；（3）关心新生代乡村教师的家庭问题，提供帮助和支持；（4）重视乡村学校建设，给予新生代乡村教师更多的组织关怀；（5）出台针对乡村教师的教师教育标准。     

Pre-arrest drug use and associated risk factors among incarcerated offenders in China

ABSTRACT

Past research has consistently reported a higher rate of drug use before arrest among incarcerated inmates than that of the general population. However, there is a lack of either qualitative or quantitative research on this topic under the Chinese setting. Drawing upon survey data collected from 1,518 inmates in a Chinese province, this study attempts to fill in the research gap by assessing the connection between risk factors associated with pre-arrest use. Roughly a quarter of all inmates in the sample had the experience of drug use before arrest. Regression analysis suggested that impulsivity, volatile temper, and perceived prevalence of drug use in neighborhood were significantly related to drug use among inmates. Two control variables include offense type and stable job, were also found to be significant predictors of drug use. Implications for research and policy were highlighted in the end.     

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.     

Leader-member exchange as a linking pin in the idiosyncratic deals - Performance relationship in workgroups

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups.     

孔子政法观念之再认识

作为儒家创始人的孔子,其法律思想带有一定的保守主义色彩。参照现代法学理论,形式意义上的"法",在孔子的政法观念中就是"刑";实质意义上的"法",在孔子的政法观念中则是德礼、政刑的规范体系。孔子所理解的"法"基本被限制在"刑"的范围内,而"礼"则部分承担了"法"的"规范"职能,这也是"仁政""德教"与"和谐"等孔子政法观念核心价值的立论基础。然而,当"法"不只是"刑"的时候,"仁政""德教"与"和谐"等核心价值则需要被重新审视。     

农民工打工地方言的习得及其影响因素分析——基于珠三角地区农民工的调查

本文基于对珠三角地区3000多位农民工的调查数据，以粤方言为例实证考察了农民工对打工所在地方言的习得状况及其影响因素。研究结果表明，41．1％的珠三角地区的农民工“可以听说”粤方言，“能听但不能说”的有40．4％，而“既不能听也不能说”的有18．5％。进一步分析发现，农民工来源地与打工地的地理接近性、农民工的职业性质、业余时间看电视、社会交往、永久性迁移意愿、年龄和所在企业规模等因素对农民工习得粤方言的效果有较显著影响。
