双循环新发展格局下锡产业演进阶段特征识别

Characteristic Identification of the Evolution Stages of the Tin Industry Under the New Development Pattern of Dual Circulation

构建以国内大循环为主体、国内国际双循环相互促进的新发展格局,是我国面临新冠肺炎疫情冲击和经济逆全球化的叠加影响的必然选择。锡作为重要的战略性矿产资源,产业演进的阶段性特征明显。本文从产业组织、产业技术、产业规模3个视角入手,选用多种方法识别中国锡产业所处的演进阶段。研究结果表明:中国锡产业表现出明显的衰退期特征;不同视角下的产业演进阶段识别结果代表着锡产业在各个层面的具体特征表现。根据锡产业在各个层面表现出的阶段性特征,有利于政府部门充分发挥调节作用、把握资源型产业发展脉络、明确不同阶段矿产资源战略重点,为双循环发展注入新动能。

It is an inevitable choice that China expects to construct a new development pattern with the domestic cycle as the main body,while mutually promoting the double domestic and international cycles,when facing the impact of the COVID-19 epi⁃demic and the superimposed impact of economic anti-globalization.Tin,as an important strategic mineral resource,has obvious phase characteristics of industrial evolution.This study identifies the evolution stages of the tin industry in China from the perspec⁃tives of industrial organization,technology and scale by using various methods.The results show that the Chinese tin industry has obvious characteristics of a decline period.The identification results of industrial evolution stages from different perspectives repre⁃sent the specific characteristics of the tin industry at various levels,which are helpful for the governments to give full play to the role of regulation.To boost the tin industry,it is also necessary to efficiently meet the market demands,clarify the strategic focus of mineral resources at different stages,and inject new momentum into the double-cycle development.
