以“省际贸易”促高质量发展:川渝地区省际调出贸易潜力研究

Promoting High Quality Development with“Inter-provincial Trade”:A Study on Inter-provincial Transfer Trade Potential in Sichuan and Chongqing

国际贸易形势严峻,在新发展格局下,开发国内需求,加快建设全国统一大市场成为紧迫要求。深化省际贸易将是刺激国内需求,提升国内市场一体化水平的有效路径。本文基于川渝地区省际调出贸易数据构造加入贸易非效率项的随机前沿引力模型研究发现,经济规模相似性和交通便利化程度是影响川渝地区省际调出的主要因素,且存在显著地方保护壁垒;同时川渝整体的省际调出尚处低效率,且与西部-东部-中部地区贸易效率呈递减态势,存在"中部塌陷"现象;主要矛盾在于川渝调出规模较大地区的贸易效率反而偏低,仍存在较大贸易空间可开发。研究验证了省际贸易壁垒的存在,应努力消除人为贸易壁垒,提升优势产业协同合作,完善交通网络,弱化市场分割影响,以深化省际贸易、开发内需,带动实现我国经济高质量发展。

Given the grim situation of international trade,it has become an urgent requirement to tap domestic demand and speed up the building of a unified national market in the new development pattern.Deepening inter-provincial trade will be an effective way to stimulate domestic demand and improve the level of domestic market integration.Based on the data of inter-provincial trade transfer in Sichuan and Chongqing region,it is found that the similarity of economic scale and the degree of transportation facilitation are the main factors affecting inter-provincial trade transfer in Sichuan and Chongqing region,and local protectionism has a significant hindering effect.It is found that the inter-provincial transfer efficiency of Sichuan and Chongqing is still low,and the trade efficiency decreases from west to east to middle.The main contradiction is that the trade efficiency of the large-scale regions transferred from Sichuan to Chongqing is relatively low,and there is still a large trade space to be developed.The research verifies the existence of inter-provincial trade barriers,and it is necessary to eliminate artificial trade barriers,enhance the cooperation of advantageous industries,improve the transportation network,and weaken the impact of market segmentation,so as to deepen inter-provincial trade,develop domestic demand,and promote the high-quality development of China s economy.
