电子商务对消费影响的实证研究

Empirical Study of Effects of Electronic Commerce on Consumption

电子商务的快速发展给消费领域带来了深刻的变化。对近年来网络零售与社会消费品零售总额的增长数据进行分析和对比,发现网络零售对居民消费起到了积极的拉动作用。在此基础上,利用2005—2015年间电子商务相关指标、人均可支配收入、人均居民消费水平等数据,引入偏最小二乘法,建立多元回归模型进行实证分析,量化研究网络购物交易额、快递服务企业业务收入、网络购物用户规模与人均消费水平之间的关系。模型结果表明,各项指标均对人均消费水平有着积极的促进作用,从而表明发展电子商务能有效拉动消费需求。

As one of the core technologies of CO2 emission reduction, carbon capture and storage （CCS） have alreadymade some progress both in theoretical studies and technology utilization. In view of a series of problems like poor technology,insufficient financing channels, low public awareness and imperfect law and regulation, the article comes up with anew direction of the CCS technology, that is, the Carbon Capture Utilization and Storage （CCUS）. The CCUS centersaround the utilization of CO2 after carbon capture. Both the “super algae” fostered by CO2 and the solidification of CO2 inconcrete production are the utilization of the CCUS. The development and utilization of new technologies will reduce carbonemission efficiently.
