Does E-commerce Promote Price Stability?—Evidence from Pure Milk Products in China
Since 2012,the fluctuation of China's Consumer Price Index(CPI)has significantly nar-rowed,and the development of the e-commerce market has also significantly accelerated during the same period.Taking pure milk products as the research object,matching offline retail data purchased from a globally renowned market research company with online retail data from Tmall Supermarket,we find that for every 1%increase in the proportion of online sales to total sales,the offline price volatility will de-crease by 3.2%-13.2%.The results of counterfactual simulation show that without online sales channels,the overall price volatility may increase by 22.8%.This result indicates that e-commerce platforms are in-tegrating local markets more closely and enhancing price stability.
