ERP与MRO系统集成过程建模与应用研究

为了实现产品生产阶段到服务阶段业务与数据的有效集成,从业务层和数据层对制造服务系统中的大修维护维修(MRO)与企业资源计划(ERP)的集成过程进行了建模与分析,对ERP与MRO系统之间的业务过程和信息交互过程进行了分析,建立了二者的业务集成框架模型,分析了ERP与MRO系统的数据结构转换过程,提出了二者数据集成模型。应用Web Services完成了ERP与MRO的系统集成开发,包括服务BOM集成、备品备件管理集成等。研究结果实现了制造和服务阶段关键产品数据信息的集成与反馈,打通了从制造到服务阶段的数据传递与集成,对进一步研究复杂产品生命周期管理的信息集成具有一定的借鉴意义。     

Inequality and entrepreneurial thresholds

We explore the relationship between inequality and entrepreneurial activity. Drawing on cross-sectional data from a largescale survey of the economic conditions of individuals across India, we develop a number of dimensions of inequality to explore empirically how inequality interacts with entrepreneurship, operationalized as self-employment or as employing other people. We find compelling evidence that there are thresholds to becoming self-employed, and even more so to assembling the combinations of resources and personal attributes required to become an employer. Greater inequality leaves more people unable to make the transition to self-employment, leaving casual laboring as the occupation of necessity. At the same time, inequality increases the number of employers in a society, by concentrating resources - particularly land and finance - enough for significant numbers of people to be able to cross this higher threshold. Lastly, greater differentiation into social or religious groups curtails the ability to cross either entrepreneurial threshold, presumably by limiting the extent and benefits of social networks of value for entrepreneurship.     

水权配置视角下新型农业节水机制和路径研究

加快实施最严格水资源管理制度的重要目标是形成以节水为目标的新的社会运行机制和社会治理模式。农民在农业灌溉中自发形成的用水组织是这一变革中的重要社会力量。通过对农民用水协会特征的分析,认为在"水权配置"的视角下,发展与规范农民用水组织,变原有农业用水过程中的行政管控为社会治理,是建立农业"节水型"社会并支持其良好运行的重要保障,并就如何健全农民用水组织的内部治理结构、克服农民用水组织自身的消极因素提出了建议。     

城市化进程中的乡村衰落现象：成因及治理——“乡村振兴战略”实施视角的分析

党的十九大报告提出了“实施乡村振兴战略”。乡村振兴是“中国梦”不可或缺的组成部分，城市化进程中的乡村衰落现象不容忽视，乡村问题的解决关系到乡村振兴战略能否实现和现代乡村能否建成。为此，剖析了我国乡村衰落的成因，探索了乡村振兴战略落实的办法，提出了现代乡村建设的可能路径。     

我国秸秆综合利用面临形势与对策研究

[目的]为加快推动秸秆资源化利用,促进农业绿色发展。[方法]文章在系统梳理我国秸秆综合利用政策文件、相关文献的基础上,全面分析了我国农作物秸秆禁烧和综合利用的发展阶段,提出了秸秆利用面临的形势和存在的主要问题。[结果]我国秸秆综合利用从时间序列上,可以划分为起步阶段、强力推进阶段和攻坚阶段。城镇化的快速推进、农村能源结构的调整、农业供给侧结构性改革的实施、农作物季节矛盾突出等,成为秸秆综合利用面临的新形势、新挑战。当前推进秸秆综合利用存在四大方面问题:秸秆还田成本较高,区域技术规范和技术适宜性缺乏;受"成本地板"和"价格天花板"双重挤压,秸秆产业化利用发展困难;秸秆收储运成本高,技术装备水平低,用地、运输问题尚未解决,收储运体系建设不健全;关键性政策工具尚未破题,缺乏普惠性、针对性的资金扶持。[结论]针对形势与问题,提出了推进秸秆资源化利用的4条对策建议:开展县域秸秆全量化利用、分区施策确定秸秆利用方向、加强政策工具集成创设、扩大试点示范引导。     

Overconfidence and tax avoidance: The role of CEO and CFO interaction

We investigate how overconfident CEOs and CFOs may interact to influence firms’ tax avoidance. We adopt an equity measure to capture overconfident CEOs and CFOs and utilize multiple measures to identify companies’ tax-avoidance activities. We document that CFOs, as CEOs’ business partners, play an important role in facilitating and executing overconfident CEOs’ decisions in regard to tax avoidance. Specifically, we find that companies are more likely to engage in tax-avoidance activities when they have both overconfident CEOs and overconfident CFOs, compared with companies that have other combinations of CEO/CFO overconfidence (e.g., an overconfident CEO with a non-overconfident CFO), which is consistent with the False Consensus Effect Theory. Our study helps investors, regulators, and policymakers understand companies’ decision-making processes with regard to tax avoidance.     

铁路的长期经济影响:基于中国1980年铁路线的研究

铁路与经济发展之间的关系得到了大量的研究，但均集中于短期经济影响，且很少关注铁路在发展中国家从传统农业社会向工业社会转型过程中的作用。文章使用中国1980年的铁路线研究了铁路在中国转型期对县域经济发展的长期影响。研究发现，铁路开通对县域经济发展具有显著的长期促进作用，具体来说，以2000年数据为例，1980年铁路线对以GDP为衡量指标的经济发展的年均促进作用为1.16%。排除了无法观测因素和溢出效应、控制县级异质性、以及使用"三线建设"作为外生冲击的结果均支持上述结论。机制检验发现，铁路促进了县域层面的工业化，同时还显著增加了县域层面的外商投资和出口，进而促进了经济发展。本文的研究不仅提供了铁路的长期经济影响的经验证据，同时也揭示了以铁路为代表的基础设施对经济转型的作用，从而有助于理解中国经济增长奇迹，也为其他发展中国家转型提供了借鉴。     

Effects of CSR on affective organizational commitment via organizational justice and organization-based self-esteem

This study examined how employee perceptions of corporate social responsibility (CSR) influenced their affective organizational commitment (AOC) via procedural justice and organization-based self-esteem (OBSE). Using survey data collected from 203 employees working for a hospitality company, hypotheses were tested using structural equation modeling. The results showed that economic and philanthropic CSR did not have significant effects on procedural justice, but had significant direct effects on AOC. The findings also showed that procedural justice had a significant effect on OBSE, and both procedural justice and OBSE had significant effects on AOC. In addition, the results suggested that ethical CSR programs can have a positive impact on employees’ AOC via their procedural justice and OBSE. This study contributed to the literature by developing a CSR-procedural justice-OBSE-AOC model, guided by social exchange and self-consistency theories, and empirically testing it within a hospitality context.
