Product Space Structure and Comparative Advantages Dynamic of Agricultural Products: An Analysis and Prediction Based on High-Dimensional Panel Data

Most of China’s agricultural products have lost comparative advantage,which goes against the development of agricultural economy.Recognising the inherent law of product dynamic comparative advantages is the precondition of reversing this situation.Based on product space theory,employing a data sample of 65 types of agricultural products in 52 countries from 2000 to 2010,this paper probes into the form of agricultural products space,examines the relationship between agricultural products space structure and dynamic comparative advantage based on the High-Dimensional panel data model,and analyses how to select the cultivation target of China agricultural products with comparative advantage.The major findings are: agricultural products space is heterogeneous;product density is positively related to dynamic comparative advantage of agricultural products;the products owned high proximity to the collection of advantage products will acquire comparative advantage easily.Intervening and vectoring the dynamic comparative advantage of agricultural products on the basis of inherent law and choosing applicable product in line with its density will promote more agricultural products to achieve comparative advantage.
