互联网发展与创新绩效:三维理论框架和异质性验证

在新一轮科技革命背景下，企业经济活动越来越依赖于互联网，因此探讨中国互联网发展能否有效提升创新绩效，具有重要的理论价值和现实意义。文章构建了互联网发展影响创新绩效的三维理论框架，同时从"质量-数量"二分视角，采用2011-2016年省际面板数据，借助面板个体效应模型对二者相关关系予以实证分析，研究结论如下：（1）互联网通过去壁垒、去中心、去中介，从要素、组织、生产范式三个维度分别经由要素重组、组织变革和供需迭代促进了创新绩效。（2）在全国层面，互联网发展和创新质量间存在U型关系，而互联网发展与创新数量间则表现为倒U型关系，且拐点值存在明显差异。（3）在分区域层面，东中西部互联网发展与创新质量间分别呈现出U型、U型、倒U型关系，与创新数量则均表现为倒U型关系。（4）由于不同省份2016年互联网发展水平分布在拟合线拐点两侧的位置不同，各省份未来政策着力点有所差异。（5）数据驱动、生态网络、用户主导分别与互联网发展深度复合影响了创新绩效，但在显著度上存在差异。综上，应从互联网建设、推广与应用，研判区域异质性，发挥调节变量的正向效应三方面重点突破，最大化互联网创新绩效，促进经济高质量发展。

军民科技协同创新要素融合机制研究

构建一体化国家战略体系和能力是新时代实施军民融合战略的重要目标，军民科技协同创新则是实现该目标的必然选择。基于扎根理论建立军民科技协同创新影响因素体系，通过分析影响因素间的交互关系构建系统动力学模型。根据模型对案例进行仿真分析，考察单因素作用、多因素协同作用、多因素非协同作用条件下协同创新水平变化情况。从军民科技协同创新内涵、结构、功能实现3个层面揭示要素融合机制。据此，为国家军民深度融合提供相应政策建议。     

Does economic policy uncertainty raise corporate precautionary cash holdings? Evidence from China

Using China as the research setting, this paper investigates the relationship between economic policy uncertainty and corporate precautionary cash holdings. Empirical results show a U-shaped relation between economic policy uncertainty and corporate precautionary cash holdings. Empirical analysis, in terms of ownership structure, firm size, corporate competitiveness and geographical location, further shows that (i) the effects for economic policy uncertainty in both state-owned and non-state-owned enterprises are significant, but the effect is stronger for state-owned enterprises; (ii) such significant effect is also found more strongly in small and medium-sized enterprises and highly competitive enterprises; and (iii) the effects for eastern, central and western China are all statistically significant, but the effect is strongest for eastern China.     

产能治理与企业债务结构再平衡—基于商业信用与银行信贷关系视角

我国上市制造业企业的商业信用与银行信贷关系存在长期互补特征,但信号理论对互补强度的演变过程缺乏有效的解释力.为探索信号理论之外的互补机制,反思企业债务结构的信贷偏移效应,文章提出了产能驱动假说,利用面板门限模型,得到了以下结论:(1)商业信用与银行信贷会随产能增长而呈现从"替代"到"互补"的演变特征,且互补强度(单位商业信用上升伴随的信贷上升)会随产能膨胀出现从"弱"到"强"的二次突变特征,即产能扭曲会使企业债务结构快速向银行信贷偏移,这为理解企业信贷依赖的形成路径提供了产能层面的微观解释.(2)企业债务结构再平衡能力具有异质性,高研发投资及低调整成本企业借助产能治理来修正信贷依赖的能力更强,因此降低调整成本、扶植企业创新应成为优化融资结构的重要政策路径.文章在信号理论之外提出了产能驱动假说,解释了我国企业债务结构扭曲的动态特征,并从技术创新与调整成本视角为推动企业实现债务结构再平衡提供了政策参考.     

东北地区粮食型农户家庭农场经营风险认知的影响因素分析

［目的］东北地区作为维护国家粮食安全的“压舱石”，准确而系统地掌握东北地区粮食型农户家庭农场经营风险认知水平，为政府部门精准实施粮食型农户家庭农场配套扶持政策提供参考。［方法］文章利用黑龙江、吉林、辽宁3省301个粮食型农户家庭农场调研数据，运用交叉列表和多元有序logit模型分析家庭农场经营风险认知水平及其影响因素。［结果］（1）6312%的粮食型家庭农场有一定风险认知能力，土地经营面积在333~1333hm2（50~200亩）与1333~3333hm2（200~500亩）的家庭农场风险认知处于中等水平， 3333hm2（500亩）以上家庭农场经营风险认知低； （2）玉米种植型家庭农场风险认知水平高于水稻种植型家庭农场； （3）年龄、是否村干部、劳动力数量、土地经营规模、是否有自然灾害、农产品市场价格波动、是否“三品一标”认证、金融支持、农推人员技术指导和新型经营主体间合作稳定对东北地区粮食型农户家庭农场经营风险认知有影响。［结论］应培养家庭农场主个人特质，鼓励支农惠农政策向规模适度的家庭农场倾斜，从流程入手提高家庭农场风险防范能力。     

Managing security risks for inter-organisational information systems: a multiagent collaborative model

Information sharing across organisations is critical to effectively managing the security risks of inter-organisational information systems. Nevertheless, few previous studies on information systems security have focused on inter-organisational information sharing, and none have studied the sharing of inferred beliefs versus factual observations. In this article, a multiagent collaborative model (MACM) is proposed as a practical solution to assess the risk level of each allied organisation’s information system and support proactive security treatment by sharing beliefs on event probabilities as well as factual observations. In MACM, for each allied organisation’s information system, we design four types of agents: inspection agent, analysis agent, control agent, and communication agent. By sharing soft findings (beliefs) in addition to hard findings (factual observations) among the organisations, each organisation’s analysis agent is capable of dynamically predicting its security risk level using a Bayesian network. A real-world implementation illustrates how our model can be used to manage security risks in distributed information systems and that sharing soft findings leads to lower expected loss from security risks.     

“荷兰病”型旅游地:内涵解析与识别流程

"荷兰病"是一个经济学领域的概念,指一国或地区某一产业部门异常繁荣,而其它产业发展相对滞后的现象。在中国旅游产业发展实践中,存在着以丽江市、张家界市、三亚市、黄山市和阿坝州为代表的以旅游业为单一支柱产业,区域经济发展高度依赖旅游业的旅游地。文章创造性地提出了"荷兰病"型旅游地的概念,并系统阐述了"荷兰病"型旅游地的内涵特征、形成条件和识别流程,运用Eviews7.0软件对上述五个城市进行"荷兰病"识别的计量经济分析,发现都属于典型的"荷兰病"型旅游地。     

Corporate Opacity and Cost of Debt for Family Firms

This paper uses a sample of Chinese firms to examine the impact of corporate opacity on the relationship between family control and firms’ cost of debt. We find that family control is associated with a lower cost of debt on average, and a negative impact exists mainly in firms with relatively low corporate opacity. We further provide evidence that the moderating effect of corporate opacity becomes more pronounced when investors’ perception of controlling families’ moral hazard of expropriation is higher. Our results are robust to alternative opacity proxies and controlling for endogeneity of family control using the instrumental variable method. Our study highlights that controlling families are heterogeneous in their impact on the shareholder–debtholder relationship in family firms, and debtholders view corporate opacity as an important reference in assessing the extent of potential agency conflicts in China.
