西部地区农业参与国家价值链分工的程度及位置研究

文章基于2012年和2017年中国省级多区域投入产出表构建价值链“参与程度—复杂程度—生产位置”指数框架，对西部地区农业参与国家价值链的程度及生产位置等进行分析。本文得出的主要结论为:相较于参与其他地区价值链的程度，西部各省份农业参与东部地区价值链的前向参与程度指数明显较高；大部分西部省份对区域内部和外部地区的后向产业关联增强；西部地区参与国家价值链的前向和后向生产长度都有所减少。在研究期内，西部地区农业在国家分工网络中从价值链的上游变为下游，在东北地区分工网络中处于价值链上游，在东部地区处于价值链下游。根据研究结论，本文提出应沿产业链推动跨省、跨区域产业协同合作，提升农业科技水平，延长农业价值链的长度，以形成国内农业产业链大循环。

A Study on the Degree and Position of Agricultural Participation in the Division of Labor in the National Value Chain in the Western Region

Based on the multi-regional input-output table at the provincial level in China from 2012 to 2017, this paper constructs the value chain index framework of “participation degree-complexity level-production location”, and analyzes the agricultural participation degree of western regions in national value chain and its production location. The main conclusions are as follows, compared with participation degree in value chains of other regions, the forward participation index of agricultural participation in the eastern value chain of western provinces is significantly higher, the backward industrial linkages of most western provinces with internal and external regions are increasing, and the production length in both forward and backward of western regions’ participation in national value chain has shortened. During the research period, the position of western regions in the national division of labor network has changed from relatively upstream to downstream; the same is true in the eastern regions. While in the northeast regional division of labor network, it is in a relatively upstream position. Therefore, we should promote cross provincial and cross regional industrial cooperation along the industrial chain, improve the science and technology level of agriculture, extend the length of agricultural value chain, and form a large circulation pattern of domestic agricultural industry chain.
