Research on the Factors of Rice Consumption Demand Based on LDA-GRA Analysis

Rice is one of the important rations in China and plays an important role in the construction of the national food security system. The change of its demand has a significant impact. This paper crawls the text data of 52,742 online rice comments on Jingdong Mall, and uses LDA-GRA model and Internet text big data mining technology to analyze. It is concluded that there are six main factors affecting rice consumption demand, from strong to weak in order: price, packaging, place of origin, taste, logistics and fragrance. With applying Maslow’s demand theory and combining the strategic demands of national supply-side structural reform, this paper puts forward countermeasures and suggestions for government and enterprise supply-side reform.
