Abstract:
Based on the price data of 10 main vegetables in Heilongjiang Province from 2004 to 2021，the GSADF method was used to measure and compare the risk of vegetable market bubbles in Heilongjiang Province.The results showed that there was no price bubble for two kinds of vegetables，and there were price bubbles for eight kinds of vegetables.The time period during which the price bubble appeared accounts for a small proportion in the sample period，but it was mostly accompanied by a sharp rise or fall in prices.Among the 10 main vegetables，there were two non-risk varieties，four low-risk varieties，and four medium-risk varieties.Based on the research results，we put forward relevant countermeasures and suggestions to ensure the healthy and stable operation of the vegetable market in Heilongjiang Province from the aspects of establishing an effective early warning and response mechanism，and developing targeted monitoring and control measures according to different varieties.
