The invention provides an esterification method of perfluorosulfonyl fluoride resin and a preparation method of perfluorosulfonic acid resin, and the esterification method comprises the following steps: mixing perfluorosulfonyl fluoride resin, fatty alcohol and an organic alkaline compound for esterification reaction to obtain an esterification product. According to the esterification method of the perfluorosulfonyl fluoride resin provided by the invention, the organic alkaline compound, the fatty alcohol and the perfluorosulfonyl fluoride resin are mixed and subjected to esterification reaction, so that introduction of water and generation of salt substances such as sodium fluoride can be avoided, the esterification efficiency of the perfluorosulfonyl fluoride resin is effectively improved, meanwhile, the process of intermediate water washing is simplified, and the yield of the perfluorosulfonyl fluoride resin is improved. The industrial production is easy to realize. 本申请提供了一种全氟磺酰氟树脂的酯化方法和全氟磺酸树脂的制备方法，该酯化方法包括
