Abstract: The supply-side structural reform is put forward under the background of mismatch between supply and demand and not sound development of economy，with the fundamental purpose of decreasing the low-end and invalid supply while increasing the high-end and effective supply. At present，for weather service，a special commodity，the phenomenon of mismatch between supply and demand is common. Therefore，it is necessary to carry out the research and practice of supply-side structural reform of weather services. By the method of system analysis， the contradiction between increasing and higher demands of weather service and limited resources and service capability is getting more and more sharp， conflicts and problems of mismatch， imbalance， incongruity between weather service supply and demand has become increasingly prominent，especially invalid and oversupply of popular low-end weather service products while insufficient supply and ineffectiveness of personalized high-end products. The fundamental reason lies in the shackles of institutional mechanisms for supply structure，and also the constraints of lack of scientific and technological support and innovation for supply. Through the innovation of weather service mechanism，increase of the effective supply， reform of supply channels and other measures，the low-end and invalid supply of weather services are reduced and the multi-level， targeted， specialized and personalized weather service supply are improved，which is the objective point of supply-side structural reform of weather services.
