城乡炫耀性消费差异的根源探索

运用中国家庭追踪调查数据,研究发现:农村家庭的炫耀性消费支出比例显著高于城镇家庭,且这一结果随时间变化比较稳健。进一步研究发现,在考虑了家庭参照群体的平均收入之后,城乡炫耀性消费差异不再显著,且参照群体的平均收入对家庭炫耀性消费的影响显著为负。这很可能来源于家庭为寻求社会地位而消费的动机,更高的社会地位意味着更多的财富和带来更高的收益。炫耀性消费充当了家庭社会地位的信号,向其参照群体传递了自身的收入水平状况,参照群体的平均收入越低,消费者寻求社会地位的消费动机越强。农村家庭参照群体的平均收入较低,所以其寻求社会地位的动机更强、炫耀性消费水平更高。因此,寻求社会地位的消费动机是城乡炫耀性消费差异的主要原因。     

政府补贴促进制造业企业研发投入了吗?——基于资本结构的门槛效应研究

本文以2016~2018年沪深股市的制造业上市公司为研究样本,通过建立门槛效应模型,验证了政府补贴与企业研发投入的作用关系会随着资本结构的变化而变化。研究发现,政府补贴能够促进企业研发投入,并且在资本结构的调节作用下呈现三重门槛效应。进一步研究还发现,政府补贴对非国有企业研发投入的影响系数更高。因此,政府研发补贴政策需要综合考虑企业资金状况、企业性质,建立有效甄别机制,实施差异化补贴策略,加大对非国企补贴力度,拓宽中小企业融资渠道。     

An empirical investigation of water consumption forecasting methods

Many regions on earth face daily limitations in the quantity and quality of the water resources available. As a result, it is necessary to implement reliable methodologies for water consumption forecasting that will enable the better management and planning of water resources. This research analyses, for the first time, a large database containing data from 2 million water meters in 274 unique postal codes, in one of the most densely populated areas of Europe, which faces issues of droughts and overconsumption in the hot summer months. Using the R programming language, we built and tested three alternative forecasting methodologies, employing univariate forecasting techniques including a machine-learning algorithm, with very promising results.     

Non-stationary additive utility and time consistency

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in $t$, the date of decision and in $s$, the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on $t$. The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents.     

A gramscian perspective on field dynamics. The case of the privatization of Italian steel industry

Institutional fields are not static, they undergo times of fragmentation and times of settlement. Neo-institutional research has long explained the settlement of fields as either the effect of political manoeuvring of actors, or of discursive activity influencing cultural codes, narratives and symbols. But can these processes really be considered in isolation? In this paper, we propose to adopt a comprehensive view on fields’ dynamics, one that embraces the interaction of political and discursive manoeuvring to explain how fragmented fields manage to settle. To do so, we build on the Gramscian concept of hegemonic practices as discursive and political processes that integrate cultural equivalence among actors with political alliances based on aligned interests. Hegemonic practices align actors in a new historical bloc (a new settlement). Through this lens, we interpret the case of the Italian State steel privatization (1984–1995) and propose a process model explaining what yields fields’ dynamics from fragmentation to settlement. The model highlights the action of diffused agency in field dynamics, thus overcoming the obsolete challenger/incumbent view, and the need of becoming a historical bloc for alliances to stabilize a field.     

体验型产品在线评论与消费意愿及销量的关系——以价格为调节变量

随着网络在线交易的迅猛发展,在线评论等网络口碑传播的重要性日益凸显。以体验型产品为研究对象,以信号理论和"刺激-反应"理论为指导,建立"在线评论-消费意愿-在线销量"模型分析三个要素之间的关系机理,并采用中介效应检验和调节效应检验进行验证,结果显示:在线评论作为一种信息刺激,其数量对体验型产品在线销量具有显著的正向影响,但在线评论质量效价评分对体验型产品在线销量的影响不显著,这与产品的类型有关;在线评论一是直接对在线销量产生影响,一是通过中介变量(即作为消费意愿替代变量的收藏量)传递影响,对在线销量产生作用;商品价格在在线评论和在线销量的直接和间接关系中都起到了正向调节作用,这与体验型产品交易过程中价格质量信号功能强于促销功能有关。实践中,企业可通过一些激励设计提高消费者在线评论参与度;进行更加科学化的网页设计,完善收藏功能,以方便消费者进行筛选和比较;注意防止盲目降价行为给消费者带来的负面影响,发挥好价格的信号作用。     

东南亚国家社交商务与非本土节日消费行为分析——以中国春节为例

在世界范围内,中国春节越来越受消费者欢迎,特别是东南亚消费者会在社交商务中参加中国春节活动。然而,现实中却存在一个矛盾的现象,即一些东南亚消费者春节期间热衷于购买中国商品,而春节过后却抵制中国商品。实证研究发现,东南亚消费者并未完全从态度上偏好中国春节和中国商品,只是出于社交商务的需要才参与中国春节和购买中国商品。东南亚消费者可区分为文化杂食型和节日身份型两个细分市场。其中,文化杂食型消费者包容并喜欢多元文化,会长期偏好中国节日和中国商品;节日身份型消费者仅在中国节日期间会参与中国节日和购买中国商品。这样的结论对指导中国企业实践具有重要价值,首先,为更好地响应“一带一路”倡议,应树立中国品牌意识,在“一带一路”沿线国家培育偏好中国文化和产品的朋友圈,转变消费者态度;其次,为更好地实施“走出去”战略,应在国际市场进行文化杂食和节日身份的细分,对文化杂食型消费者以文化为纽带培育其长期稳定的消费习惯,对节日身份型消费者通过营销策划刺激其消费;其三,为成功进入东南亚市场,对在东南亚运营的社交商务,应侧重培育消费者亲中国文化与产品的态度,并增加其使用社交商务平台的愉悦感。     

消费国际化趋势下的中国对策

随着我国经济发展和融入全球化水平提升,国际影响力不断增强,消费升级进程推进,我国消费市场主体、客体和载体的国际化特征渐趋明显。本文基于对消费国际化理论的回顾,对消费国际化的内涵进行了界定,在总结当前我国消费国际化的特征及所面临的问题基础上,提出了丰富中高端商品供给、优化进口商品消费环境、健全免退税服务体系、推动扩大入境旅游等一系列政策建议。本文认为,当前我国消费市场主体、客体和载体等各要素的国内外融合程度仍然有待提升,我们应该顺应消费国际化发展趋势,推动我国消费升级朝着更高层次发展。     

社会规范对绿色消费的影响及作用机制

绿色消费是我国推进生态文明建设所倡导的消费行为,本文将社会规范划分为描述性规范、动态描述性规范和命令性规范,探讨了社会规范对绿色消费的影响及作用机制。通过两个实验研究发现,描述性规范、动态描述性规范、命令性规范对绿色消费的促进作用显著,三者对绿色消费的促进作用无显著差异;描述性规范、动态描述性规范会激活消费者的个人规范,个人规范在描述性规范、动态描述性规范影响绿色消费过程中发挥部分中介作用;命令性规范会引发消费者的后果认知,进而激活个人规范,后果认知与个人规范在命令性规范影响绿色消费过程中发挥完全中介作用。因此,可以发挥描述性规范、动态描述性规范对绿色消费的引导示范作用和命令性规范对绿色消费的监督作用,激活绿色消费的个人规范水平,更为有效地促进绿色消费。     

The impact of dual network structure on firm performance: the moderating effect of innovation strategy

ABSTRACT

Firm innovation is embedded in a collaboration network among researchers and a knowledge network composed of knowledge elements; the two networks are decoupled. Guided by social network theory, this study puts forward the definition and the classification of firm dual network structure, probes into the influence of dual network structure on firm performance, and explores the alignment between innovation strategy and firm dual network structure. We conduct an empirical study of 183 listed companies in China from 2004 to 2018. It is found that the four types of dual network structure all have positive impacts on firm performance, and the impact of a collaboration network is slightly higher than that of a knowledge network. Besides, innovation strategy plays a positive moderating role in the relationship between dual network structure and firm performance. Our findings provide new ideas for firms to identify and optimise knowledge and collaboration network structures and match them with innovation strategy to improve performance.
