Research on the Development of Agricultural Complex in Chinese Provinces Based on Input-Output Analysis

Chinese provinces and regions have huge differences in agricultural resource endowments and uneven levels of agricultural industry development, resulting in inconsistent influence of agricultural complexes on the economic development of China's provinces and regions. This paper uses the input-output model to divide the agricultural complex into four links: agricultural production input, production, agricultural product processing and final distribution of agricultural products. By estimating the GDP of agricultural complex in 30 provinces and cities in China in 2002, 2007, 2012 and 2017, the paper analyzes the structure composition and change trend of the agricultural complex's share of GDP and the four links of agricultural complex. On this basis, this paper uses the two indicators of agricultural resource abundance and agricultural product processing development to divide the agricultural complexes in 30 provinces and regions of China into four types: the first type is the area with rich agricultural resources and developed processing industry. The second category is the area with developed agricultural resources and backward processing industry. The third category is the area with poor agricultural resources and developed processing industry. The fourth category is the region with poor agricultural resources and backward processing industry, which provides a reference basis for the coordinated development of agricultural industries in various provinces and regions and complements each other's advantages.
