一个国家的经济发展过程实际上是经济结构不断调整和优化的过程 ,而所有制结构的调整与优化是整个经济结构调整的重要组成部分 ,同时也是体制改革“攻坚战”的重要内涵。党的十五届五中全会强调 ,“十五”期间要把坚持在发展中推进经济结构调整、在经济结构调整中保持快速发展? The process of economic development in a country is actually a process of constant adjustment and optimization of the economic structure. Adjustment and optimization of the ownership structure are an important part of the entire economic restructuring and meanwhile an important connotation of the “tough battle” in structural reform. The Fifth Plenary Session of the 15th CPC Central Committee emphasized that it is necessary to uphold the adjustment of economic structure and rapid development in economic restructuring during the “Tenth Five-Year Plan” period.
