→ indicates the causal relationship, the number on it is the path coefficient; ? indicates the correlation, the number on it is the correlation coefficient, * and ** indicate significant correlation at 0.05 and 0.01 levels, respectively. A is the Huang-Huai fertile dry land, and B is the Huang-Huai barren dry land
