Relevant personnel of the Municipal Price Bureau pointed out that there are seasonal factors in the current increase in vegetable prices. Before and after beginning of autumn, vegetables were listed in a "green and yellow" period, and vegetables were in a seasonal transition period. Vegetables are gradually withdrawn from the market in summer, and vegetables are no longer supplied in batches in autumn, and the market volume is reduced in stages. According to the summary of the market monitoring data of the province in the past five years by the provincial price monitoring center, August is a period of high price in a year, which is generally about 20% higher than that in June and July. This year, Shandong vegetable wholesale price index rose by 27.5% at the end of August and July, showing a regular price increase.
