中国战略性新兴产业发展与金融支持的动态关联——基于沪深A股上市公司的经验数据

金融是现代经济的核心,战略性新兴产业发展离不开金融支持。以近三年七大战略新兴产业400多家上市公司季度数据为基础,通过面板数据协整分析和格兰杰因果检验探讨两者之间的动态关联。结果显示：金融支持对战略性新兴产业发展具有正效应,金融机构的支持力度提高1%,战略性新兴产业发展水平将提高0.76%。短期内两者呈现单向因果关系,金融支持是战略性新兴产业发展的原因,在长期两者互为因果关系。     

Industrial sales people as market actors

We develop the concept of boundaries in the context of sales personnel and their counterparts encountering and negotiating these while they undertake work to shape markets and build relationships. Drawing on a case study from production chemistry, we show that market shaping implies a mutual development of relationships, goods and services exchanged, and boundaries. In particular, we show that while relationships can submerge and obscure parts or dimensions of boundaries to other market actors, normal business activities such as testing new products and adapting products to changes in environmental legislation make visible some material dimensions of the exchange object, which can attract attention from other sellers. Visibility finds an expression as those market objects are exchanged, such that objects can be devices by which other actors join in and position themselves and their objects within markets.     

How companies strategise deliberately in networks using strategic initiatives

In this paper we contend that there is little idiographic empirical research that considers the issue of deliberate networking action in full-faced network contexts. We address the issue through the use of strategic initiatives as a form of deliberate networking action. IMP research argues the ability of an organisation to manage in a network context that involves the pull of the network and the action of the individual organisation (Håkansson & Ford 2002; Möller & Halinen 1999; Möller & Svahn 2003; Ritter, Wilkinson & Johnston, 2004; Zolkiewski 2007). Yet the paradox logic reminds us that a firm still needs to act, to try and control and influence, to suggest ideas and initiatives, to set limits and to seek opportunities. Strategic initiatives allow for conscious strategising at the same time as ongoing adaptations in activities and resources occur. Based on two complementary case studies we suggest five approaches for deliberate strategising in full-faced network contexts. These are i) strategising based on network pictures in the absence of direct interaction, ii) strategising in the presence of a network audience, iii) strategising among deliberate equals, iv) strategising among imaginative equals, and v) strategising as open and absorptive bystander. The five approaches can be used separately or in combination.     

Induced effects of smart food/agri-systems in Japan: Towards a structural analysis of information technology

The Japanese government decided to promote “smart society” in the 5th Science and Technology Basic Plan. The purpose of this research is to evaluate the effects of information and communication technology (ICT) in smart society by input-output analysis using the food industry and agriculture as examples. We define food production and agricultural activities utilizing ICT as a smart food-agri system, and try to analyze the effect of such a system on the economy as a whole. As a result, we confirmed that such a system has a large economic ripple effect on information sectors. At the same time, through these analyses, (1) we redefine information goods and service sectors, (2) we describe the new management sectors that are using these goods and services, but are not currently independent businesses, and (3) we clarify new industrial structure that exists in “smart society” using ICT.

产业投资基金及其组建模式的探析——基于文化产业投资基金的角度

国际经验表明,产业投资基金能够推动产业升级,提高投资效率,促进经济发展.我国文化产业现处于初级阶段,需要金融工具辅助其发展,文化产业投资基金的出现为文化产业的发展提供了更好的金融平台.本文主要分析文化产业投资基金及组建模式,并具体分析公司型、信托(契约)型和有限合伙型三种组建模式的应用.由于文化产业自身、市场环境和中国产业基金发展水平等条件的约束,不存在最优组建模式,需根据实际情况选择合适的组建模式.最后,从完善政策法规、完善金融服务体系、培养复合型人才等多方面提出建议,促进我国文化产业和文化产业投资基金的发展.     

城市医疗废弃物回收路径优化研究——以成都市金牛区为例

为满足城市医疗废弃物对回收处理时效性的高要求,提高城市医疗废弃物回收效率,构建了以总回收时间最短为优化目标的带有时间窗的车辆路径优化模型(VRPTW)。利用最大最小蚁群算法求解该模型,有效克服了一般蚁群算法容易早熟收敛的缺点,得到最短回收时间以及最优回收车辆数和最优行驶路径。最后,以成都市金牛区医疗废弃物回收为例,验证了模型的有效性。     

保险保障基金对中国保险业产业组织的影响

本文运用中国12家寿险公司和16家财险公司近10年来的面板数据,基于新产业组织理论,考察保险产业组织的运行规律及保险保障基金提取额对保险业产业组织的影响。估计结果显示:寿险业和财险业普遍存在过度竞争,竞争侵蚀绩效;无论是财险业还是寿险业,保险保障基金提取额对竞争活动的积极程度和市场份额具有正向影响,而与保险公司的经营绩效负相关;引入虚拟变量考察保险保障基金制度从隐性制度向显性制度变迁的经济效应发现,显性制度有利于抑制道德风险,使大多数保险公司规范自身竞争行为,扩张市场份额并提高绩效水平。     

Contagion effect of systemic risk among industry sectors in China’s stock market

This paper constructs a tail event driven network to investigate the interdependence of tail risks among industries in the Chinese stock market from 2014 to 2019, and identifies systemically important industries that have made significant contributions to risk contagion by systemic risk decomposition technique. The empirical results suggest strong linkages among industry sectors. The risk profiles of certain industries under close supply–demand relationships are positively correlated, whereas the financial industry, particularly banking, proves to be the principal risk diversifier in the network, with the household appliance, food and drink industries performing likewise an important role in risk diversification. Based on the TENQR model, further study on additional information provided by the industrial chain structure demonstrates that the upstream industry dominates the spread of risks under extreme market conditions. Our findings are of constructive significance to the anticipative introduction of corresponding policies by regulatory authorities, and are also instructive to the investors’ allocation of assets.     

混合柔性充电策略支持下的电动汽车配送路径优化

针对电动汽车在市区配送中应用越来越广泛的现象,提出了混合充电策略支持下带时间窗的电动汽车路径规划问题。在充电站,电动汽车可以选择快速充电方式充满电池或充一部分必须的电量,也可以选择直接更换满电状态的电池,这种柔性的充电策略为电动汽车提供了更灵活的运作方式,降低配送的时间和成本。通过引入充电策略相关的决策变量,在车辆路径问题的基础上,建立了混合充电策略的电动汽车路径优化的非线性混合整数规划模型。设计了一种改进的蚁群算法,通过集成局部搜索算法,提高了问题求解的效率。最后通过三个具有不同客户点分布特征的实例验证了算法的有效性,并分析了混合充电策略的影响。
