The study looked at how the food industry and agriculture are connected in China. They checked data from different years and found that agriculture relies more on the food industry to add value to its products. But, the food industry is now focusing more on processing agricultural goods deeply instead of using them directly. This change reduces the impact of the food industry on agriculture. By examining data from specific provinces between 2000 and 2002, they discovered that the food-processing industry is essential for linking agriculture and food manufacturing. To make this link stronger, speeding up the growth of the food-processing industry is crucial.
