Does Consumer Well‐Being Affect Hedonic Consumption?

This article presents a theoretical model that reveals how consumers’ long‐term subjective well‐being (SWB) influences their spending on hedonic products. Using the longitudinal data from a large national panel survey, the study found that consumers’ SWB influences spending on hedonic products via the mediating effects of their positive interpretation of life circumstances and broadened set of activities resulting from positive emotions. The results are explained using cognitive tuning theory and broaden‐and‐build theory and have implications for hedonic products providers in terms of who their target audience is and how demand for their products is generated.     

Anti-corruption,government subsidies,and investment efficiency

The problem of corruption in socio-economic development has long been a focus of academics and practitioners. To address this concern in China, the 18th National Congress of the Communist Party of China instituted a new anti-corruption policy. In this paper, we examine the impact of this recently enacted anti-corruption policy on the investment efficiency of subsidized enterprises from the perspective of government subsidies. We conclude that government subsidies have a significant positive impact on the overinvestment behavior of enterprises and that the anti-corruption work done by the government has effectively restrained the excessive investment behavior of government-subsidized enterprises. Further, we find that the anti-corruption policy is more effective in restricting overinvestment in subsidized state-owned enterprises than in non-state-owned enterprises. We examine the impact of the anti-corruption policy on excessive investment caused by government subsidies and enrich the body of research related to investment efficiency. We also provide empirical support for further research on the anti-corruption policy at the macro-market and micro-enterprise levels. The findings highlight the need to establish new cooperation between government and enterprises, to rationalize the distribution of administrative resources, and to promote the sustained and healthy development of the national economy.     

基于委托代理的独立学院科研管理研究

通过把委托代理理论引入科研工作,建立单重激励和多重激励下的委托代理模型并求解,发现科研工作者的工作热情和该项工作自身的风险性以及激励制度的实施紧密相关;在相同的条件下,激励强度系数更大,多重激励下的科研工作者比单重激励下的更努力工作。独立学院应采取物质激励与精神激励相结合的激励机制。

电感耦合等离子体原子发射光谱法测定聚乙烯、聚丙烯中铬、锆、钒和铪

采用微波消解技术对以聚乙烯、聚丙烯为原料制作的食品容器、食品包装薄膜进行预处理,确定了溶样酸介质及其用量、微波消解温度、时间等关键因素,建立了一种快速测定聚乙烯、聚丙烯材料中铬、锆、钒和铪含量的电感耦合等离子体原子发射光谱法。实验结果表明,5mL硝酸和1mL过氧化氢的混合溶液即可实现样品的完全消解,同时通过优化光谱分析条件,得到铬、锆、钒和铪的检测限分别为1.0 mg/kg,0.7mg/kg,0.7 mg/kg,1.4 mg/kg。该法加标回收率在88%-103%之间,相对标准偏差（n=3）为0.84-6.4%。用于实际样品的测定,所得结果与标准样品的参考值相符。     

在央行新支付管理办法下的电子商务信用机制研究

近期中国人民银行发布了《非金融机构支付服务管理办法》,办法对从事网络支付等与电子商务支付相关的服务企业作出了相应的规范要求,这必将对电子商务信用体系带来新的建设思路。本文通过对人民银行新支付管理办法的解读,通过对已有的电子支付和预付卡的交易模型的分析,探讨了在该办法体系下的电子商务信用的建设机制,提出了运用支付服务实现信用机制的方法,并基于该方法给出了实现信用评价的模型,通过在重庆市公众城市一卡通中心的实际运行,验证了模型的合理性。
