20世纪 80年代在新贸易理论的基础上,西方学者以规模经济和不完全竞争为前提,以产业组织理论和市场结构理论为研究工具,提出了战略性贸易政策理论。该理论动摇了在规模经济和不完全竞争条件下自由贸易政策的最优性,证明了政府干预的合理性。
On the basis of the new trade theory in the 1980s, western scholars put forward the strategic trade policy theory based on the theory of industrial organization and market structure with the scale economy and imperfect competition as the premise. This theory shakes the optimality of free trade policy under the conditions of economy of scale and imperfect competition, and proves the rationality of government intervention.
