Abstract
As one of the largest watermelon consumption city in China,the development of the watermelon industry in Daxing district not only affects the direct economic interests of local farmers,but also the effectiveness of Beijing's rural industrial revitalization work.In order to better enhance the discourse power and brand influence of Daxing watermelon in the market competition,and provide a powerful lever for the government to promote the digital economy,this study relied on the actual situation of the watermelon industry in Daxing district,Beijing,and drew on the compilation methods of domestic and foreign price indices,provided a detailed introduction to the compilation process of the"China Watermelon Industry Daxing Index"from several aspects,including model construction(Laspeyres synthesis method),indicator compilation,and algorithm construction.The continuous release of the Daxing Watermelon Price Index provides an objective,scientific,and quantitative market value benchmark for the development of the watermelon industry in Daxing,Beijing,and even the whole country.On the other hand,by enhancing the participation,expression,and initiative of watermelon production and operation entities in price formation,the advantages of resource endowment,planting,and industrial agglomeration can be transformed into advantages in market price discourse.The results indicate that the upgrading and application of the watermelon price index need to be further promoted from several aspects,including expanding the range of data sample points,emphasizing authoritative release,strengthening economic attributes,and expanding its application scenarios in the financial field,gradually promoting the transformation of Beijing Daxing from a watermelon planting center to a market trading center and a price formation center.关键词
