in 2019，China’s CPI showed an overall upward trend，still in a moderate range，with PPI rising high before and low after，and once again entered a negative range under the combined action of tail raising factors falling and new price rising factors running low. In 2020，under the comprehensive influence of the new crown epidemic prevention and control and macroeconomic policies，the global economy is rapidly declining，the demand for bulk commodities is falling，and the price is falling. The influence of different areas of price is structural difference. The epidemic interferes with the pig cycle，and the inflection point of pork price may be delayed. Some countries have tightened their grain exports，and the prices of some agricultural products in China have increased，but there are still conditions to maintain stability in general. Combined with tail raising factors，it is expected that CPI growth will further expand to 3.5% in the whole year，and PPI will continue the weak trend of operation，with the decline expanding to 1.2%.
