The Chinese vegetable price was relatively high in late August because several vegetable production areas in north China suffered from extreme weather conditions. Although the price showed a steady decline during September, the overall vegetable price index was still higher than in August. There are several reasons why the overall price was still higher than in August. First, the double holiday of "Mid-Autumn Festival" and "National Day" [October 1, 2020] and the start of the new school year both stimulated vegetable consumption. Market demand significantly increased and the price went up.
Second, temperatures in north China dropped. The production seasons of celery, hot peppers, and tomatoes all approached their end. The overall supply volume declined, and that is another reason why the price went up. Third, the frequency of typhoons and heavy rainfall is higher than usual this year. Many vegetable production areas suffered the consequences of extreme weather conditions and the overall production volume declined. The price naturally went up.
The vegetable production volume in Shouguang will increase in October. And the market supply volume of autumn vegetables is also growing. The vegetable price index is therefore likely to come down.
