房产税能否抑制实体经济"脱实向虚"——来自上海和重庆的经验分析

本文利用我国35个大中城市2006-2018年的平衡面板数据,基于上海和重庆在2011年实施的房产税试点政策,运用合成控制法检验房产税政策能否抑制实体经济"脱实向虚"发展的趋势.研究结果显示,房产税政策能够有效地遏制地区房地产业新增产值占GDP的比重的上升,促使实体企业回归主业,增加实体投资,实现促进实体经济朝着"脱虚返实"方向发展的作用.鉴于此,本文提出应加快推进房产税政策在全国范围内的实施,并在政府补贴、银行贷款等方面采取一系列配套措施鼓励实体企业进行更多的实体投资.     

国内外众创经济研究述评——基于文献计量与扎根理论分析

立足众创时代特征,运用文献计量对1999—2018年间1701篇国内外众创文献挖掘分析,探寻众创经济特点主题,探析众创发展知识基础,探求众创研究演进脉络,并获取众创经济视域下核心语句和高频词语,运用扎根理论对抽取的126篇的众创文献样本进行三级编码,进而构建众创研究的整合性理论框架,探究众创研究的系统性发展图景。研究表明,众创理论假说大量问世,众创文献热点主题包括六类,众创经济研究存在两种演进趋势,众创经济治理系统理论具有三个维度;未来应关注众创主体思辨性、众创要素系统性和众创技术本土化等专题研究。     

技术并购能够带来技术创新效应吗 ——收购公司成长潜力视角

选择2009—2017年我国A股高科技产业上市公司并购事件作为研究对象，考察技术并购能否给收购公司带来技术创新效应，以及收购公司成长潜力水平对技术并购与技术创新效应的调节作用，并进一步从两维度区分不同类型技术并购以检验其技术创新效应差异。结果发现：技术并购能够显著带来技术创新产出效应和技术创新促进效应；收购公司成长潜力越大，技术并购带来的技术创新效应越显著。此外，相对技术进入型并购，技术巩固型并购更能给收购公司带来显著技术创新效应，而国内技术并购与跨境技术并购带来的技术创新效应不存在显著差异。     

集成动员理论下军民科技协同创新机制设计研究

军民科技协同创新能力是国家科技整体竞争力的重要组成部分。近年来，军民科技协同创新取得显著成效，但也存在诸多问题，严重阻碍了军民科技协同创新深入发展。因此，迫切需要对军民科技协同创新机制进行系统性设计。基于集成动员理论的核心思想，借鉴其组织模式和运行机制理论，针对军民科技协同创新机制不明晰等问题，对军民科技协同创新机制进行系统性设计，提出在军民科技协同创新管理机构的引导下，将军民科技协同创新的各种资源要素和功能集成于军民科技协同创新服务平台，为军民科技协同创新流程和成果转化流程两大板块提供相关服务，并构建相关运行保障机制，进而实现军民科技协同创新集成化、敏捷化、模块化、高效化管理，进一步完善军民科技协同创新管理体系。     

The Effect of Fuel Price Changes on Fleet Demand for New Vehicle Fuel Economy

New vehicle purchases by private companies and government agencies, or ‘fleet’ buyers, represent a significant percentage of overall new vehicle sales in the United States. Yet little is known about fleet demand for new vehicle fuel economy including how it responds to fuel price changes. Using unique disaggregated data on fleet and household registrations of new vehicles from 2009 to 2016, we estimate how fleet demand for new vehicle fuel economy responds to fuel price changes. We find that fleet purchases of low fuel economy vehicles fall relative to high fuel economy vehicles when gasoline prices increase, a finding that is consistent with fleet buyers’ taking into account capitalization of fuel costs in the second‐hand market. Our estimates imply that raising gasoline prices by one dollar would increase fuel economy of new vehicles acquired by fleet buyers by 0.33 miles per gallon. We estimate a similar response for household buyers during the same period. This result justifies basing fuel economy responses to fuel cost changes on household data alone, an assumption widely used in the vehicle demand literature and the fuel economy valuation literature. We also find, however, that the response to fuel price changes varies across the types of fleet buyers: rental companies respond strongly to fuel price changes, whereas commercial and government buyers are insensitive. Our estimates imply that an increase in the federal gasoline tax would modestly increase fuel economy of vehicles bought by households and rental companies but would have little to no impact on fuel economy of vehicles bought by non‐rental companies and governments.     

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。

A hybrid information approach to predict corporate credit risk

This study proposes a hybrid information approach to predict corporate credit risk. In contrast to the previous literature that debates which credit risk model is the best, we pool information from a diverse set of structural and reduced‐form models to produce a model combination based on credit risk prediction. Compared with each single model, the pooled strategies yield consistently lower average risk prediction errors over time. We also find that while the reduced‐form models contribute more in the pooled strategies for speculative‐grade names and longer maturities, the structural models have higher weights for shorter maturities and investment grade names.     

湖南省农业生态与农业经济耦合性测度

[目的]考察湖南省近9年来农业生态与农业经济系统耦合发展现状,探究二者发展过程中的规律,以期找出二者协调发展模式,并为湖南省农业生态环境保护、农业经济发展提供决策依据。[方法]运用耦合协调度模型,基于熵权法为各指标进行客观确定权重,结合2007~2015年湖南省农业生态与农业经济发展的相关数据,确定农业生态与农业经济的耦合匹配分析模型,采用熵值赋权法确定各项指标的权重,构建农业生态—农业经济耦合协调评价指标体系。[结果]研究结果表明,2007~2015年湖南省农业生态与农业经济的耦合协调发展基本稳定,耦合度值均在0.9以上,二者呈协调发展趋势。其中,2014年和2015年二者的耦合度较高,分别为0.975 3和0.984 3,说明湖南省在这两年的农业生态与农业经济的协调性好,农业经济与农业生态能够相互有效促进彼此的发展。同时,仍需时刻关注生态环境的承载力,降低对自然资源的无序攫取,实现经济的可持续发展。     

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.
