The following is a comprehensive analysis, the original answer has been modified, the price elasticity of demand for pork fluctuates It is relatively large, and it feels unreasonable to simply say that it is inelastic or elastic.

This is some supplement to the price elasticity of demand, as well as the price elasticity of demand and pricing strategy: (You can also add this to the analysis if you think you need it)

The following is the data of pork stock and slaughter in recent years, as well as the recent changes in pork prices: (The data are all from the Ministry of Agriculture and Rural Affairs)

In addition, there is a statistic of the proportion of meat consumption:

From the homework of CPI analysis in our course, the food category in CPI 34%, and pork accounts for about 60% of meat consumption.

I think the analysis of pork price changes mainly comes from the relationship between supply and demand (especially supply and demand).To the end, changes in live pigs and imports), in addition to macro-control policies (such as subsidies, frozen meat reserves), vaccine development, artificial meat... From the perspective of elasticity (it feels like an exercise problem) ) Some elastic data is less certain.

In terms of price forecasting, I saw that some papers mostly use the method of econometrics for regression analysis; Inventory changes predict hog supply after 10 months; there are other methods of price forecasting. Or for the practical problem that the production cycle is long, the demand is determined by the current price, and the supply is determined by the previous price, the cobweb model can also explain the mechanism of pork price fluctuations.

After reading the latest pig price data, update it:

(Data from "China Pig Network")

May be due to the current increase in supply, the price of live pigs has dropped significantly.
