本研究采用实验的方法挖掘广告调节聚焦信息对消费者非欺诈性仿冒奢侈品购买意愿的影响机理。研究结果表明,奢侈品广告信息对消费者仿冒奢侈品购买意愿的影响受消费者自尊水平的调节:对于高自尊的消费者,当广告信息为预防聚焦时,其仿冒奢侈品的购买意愿更低;对于低自尊的消费者,广告调节聚焦信息对其仿冒奢侈品购买意愿的影响不显著。广告信息对消费者仿冒奢侈品购买意愿的影响还受消费者从众倾向的调节:对于低从众倾向的消费者,当广告信息为预防聚焦时,其仿冒奢侈品的购买意愿更低;对于高从众倾向的消费者,广告调节聚焦信息对其仿冒奢侈品购买意愿的影响不显著。

在线渠道下,不同品牌的价格折扣促销的差异性会引起在线消费者品牌选择行为变化。同时,在线的价格比较机制也增加了消费者价格敏感度,如果不分离出这一重要的促销效应,那么会产生估计偏差,影响模型的预测能力。本文首先回顾品牌选择的离散模型中价格促销的研究脉络;然后构建在线渠道消费者品牌选择离散Logit模型;接着在对中国某电子商务公司的消费者实际购买可乐的面板数据分析的基础上,研究价格折扣对于该公司消费者品牌选择行为的影响效应,研究发现:(1)如果不引入价格折扣促销因素,将会过高估计价格的影响;(2)价格折扣促销对于消费者网上品牌选择有显著的影响,且影响为正效应。文章最后剖析价格折扣对在线渠道的消费者品牌选择的行为影响机理,并提出未来的研究方向。

Rational design of electrode meterials with unique core-shell nanostructures is of great significance for improving the electrochemical performance of supercapacitors. In this work, we prepare several CuCo_(2)O_(4)@Ni-Co-S composite electrodes by a controllable hydrothermal and electrodeposition route. Onedimensional nanowires can shorten the ions transport path, while two-dimensional nanosheets expose many active sites. This enables three-dimensional structured composite with high electrochemical activity. The as-prepared heterostructured materials show a specific of 1048 C/g at 1 A/g. It still maintains 75.6% of initial capacity after 20000 cycles at 10 A/g. The device delivers an energy density of 79.2 Wh/kg when the power density reaches to 2280 W/kg. Moreover, it possesses an excellent mechanical stability after repeated folding at different angles.
