中间品技术溢出双门槛效应分析

通常认为,某产业自身进口中间品（Term）和其它产业进口中间品（Tram）对该产业的技术溢出均存在公司规模过大或过小的双门槛效应。基于我国中低技术产业数据,结合公司规模相关理论,采用非线性动态面板回归技术来检验门槛效应。结果表明,Tram对我国中低技术产业的技术溢出不存在公司规模门槛效应,而Term的技术溢出存在公司规模双门槛效应。且当中低技术产业的公司规模小于0.869 097亿元总产值/个时,系数显著为正,暗示我国中低技术产业总体公司规模过于庞大,在吸收外部知识溢出时不具备充分的灵活性。     

区域“大众创业，万众创新”效率评价

以中国内地31个省（市）数据为基础,以“大众创业,万众创新”（简称“双创”）的本质及特征为依据,构建了一套区域“双创”效率评价指标体系。运用三阶段DEA方法,在控制环境因素的基础上考察了各地区“双创”投入产出转化效率。研究显示,目前各区域“双创”效率发展不均衡,规模效率和纯技术效率除个别地区达到1以外,其它地区都存在不同程度的效率缺损。最后,根据规模效率和纯技术效率大小,对31个省市的“双创”效率进行四分图归纳,根据归纳结果提出了相应的解决措施,可为“双创”可持续发展提供参考依据。     

“双11”促销活动中羊群效应的博弈分析

2013年天猫"双11"促销活动的销售额突破了350亿。这种现象的背后是羊群效应的呈现,对促销活动起到了推波助澜的作用。文章运用博弈理论对此现象进行分析。结果表明,不同博弈情形对羊群效应的作用不同,羊群效应的形成需要一定的条件。文中共列出了网民之间、商户之间、网民与商户之间三种市场主体的7种博弈情形,不同的博弈情形可运用在不同的场景中。其中博弈情形1为大家都参与,适用于优质产品的无差异化推广销售中;博弈情形2为大家都不参与,适用于假冒、伪劣、盗版、水货等产品的打击和阻隔;博弈情形3、4、6为部分人参与,适用于特定产品、特定人群的差异化销售中;博弈情形5属于参与和不参与均可,适用在商家的专卖连锁店、加盟商户或各分、子公司的联合经营中;博弈情形7属于混合策略,在竞争充分的完全市场竞争结构下出现概率较大。     

Growth, welfare and transitional dynamics in an endogenously growing economy with abatement labor

This paper sets up a simple endogenous growth model that highlights the importance of the endogenous labor-leisure choice and the allocation between production labor and abatement labor. We show that, in contrast to the common notion (e.g. [Bovenberg, A.L., Smulders, S., 1996. Transitional impacts of environmental policy in an endogenous growth model. International Economic Review 37, 861–893] and [Bovenberg, A.L., de Mooij, R.A., 1997. Environmental tax reform and endogenous growth. Journal of Public Economics 63, 207–237]), the existence of an environmental production externality is a sufficient (but not necessary) condition for environmental policies to stimulate economic growth if the labor-leisure choice is endogenously determined. In particular, since there are complementarities between public abatement and private abatement, the public abatement expenditure will have a more powerful enhancing effect on economic growth when it is accompanied by more efficient private abatement. This result also leads to a corollary to the effect that it is easier to achieve double dividends in terms of enhancing both growth and welfare if the endogenous labor-leisure choice is taken into account.In our dynamic analysis, we show that if public abatement is substantially large, dynamic indeterminacy may occur despite the absence of a positive labor externality and interestingly, this is more likely to be the case when abatement labor plays a more significant role. Besides, the transitional effects of an increase in public abatement are also investigated.     

Efficiency in the provision of social care for older people. A three-stage Data Envelopment Analysis using self-reported quality of life

Using a three-stage data envelopment analysis approach, this paper explores efficiency in the provision of social care for older people in 148 English Councils in 2009/10. Departing from D'Amico and Fernández (2012) [31] our measure of efficiency is inscribed within the production of welfare framework and based on self-reported quality of life of recipients of the services. Our results indicate a high level of efficiency, but once we control for the effects of a number of environmental variables, we found that more stringent eligibility criteria and higher assessment costs are negatively associated with the efficiency in the provision of social services.     

Double implementation in economies with production technologies unknown to the designer

Summary. This paper considers double implementation of Walrasian allocations and Lindahl allocations in Nash and strong Nash equilibria for both private and public goods economies when preferences, initial endowments, production technologies, and coalition patterns are all unknown to the designer. It will be noted that the mechanisms presented here are feasible and continuous. In addition, unlike most mechanisms proposed in the literature, our mechanism works not only for three or more agents, but also for two-agent economies, and thus it is a unified mechanism which is irrespective of the number of agents.

环境税“双赢”效应及其对我国税制改革的启示——一个基于OECD国家视角的研究

环境问题在西方发达国家上百年工业化过程中分阶段出现过,而目前在我国则集中出现,我国已进入污染事故多发期和矛盾凸显期.国外环境税的征收情况、环境税在经济合作与发展组织中的“双赢”效应,对我国环境税的设计都具有一定的借鉴作用.     

网络购物行为影响因素实证研究--基于双渠道视角

线上、线下双渠道运作已经成为互联网时代传统企业渠道变革的一大趋势,越来越多的现代消费者变成了双渠道消费者,越来越多的商家在利用传统销售渠道销售产品的同时也通过网络直销模式进行产品销售。本文基于现有网络购物影响因素文献,整合多渠道选择理论和顾客价值理论,构建了双渠道下消费者网络购物行为影响因素模型并提出相应假设。同时以桂林电子科技大学学生消费者为研究对象,以双渠道为研究视角,对消费者网络购物行为的影响因素进行了实证研究。研究得出了五个驱动消费者进行网络购物的影响因素并实证证明了其分别对消费者网络购物选择行为具有显著的正向影响。最后,针对实证分析结论,探讨了相应的实践意义与研究不足,以期为企业营销决策提供参考。     

异质性机构投资者差异化作用于双元创新投资吗——基于注意力基础观与市场迎合理论双重视角

基于2011-2020年沪深A股高新技术企业样本,探究公司治理框架下异质性机构投资者对企业双元创新投资的差异化作用机理,得出如下结论：①异质性机构投资者对于双元创新投资具有差异化影响,其中,专注型机构投资者更有利于双元创新投资;②专注型机构投资者影响决策者注意力资源配置,使其更注重探索性创新投资,临时型机构投资者基于市场迎合动机作用于开发性创新投资,且当管理层业绩和外部监管压力较大时,其对开发性创新投资的迎合动机更明显;③专注型机构投资者通过监督和激励管理层、提升企业风险承担水平作用于企业双元创新投资,临时型机构投资者通过丰富投资者情绪作用于开发性创新投资未得到验证;④产业政策有助于增强专注型机构投资者对决策者注意力的影响,使其更专注于探索性创新投资,同时也有助于提高临时型机构投资者的开发性创新迎合投资动机。研究结论为理解机构投资者差异化治理角色提供了一种新视角。
