伴随着我国企业股份制改革飞速发展，具有多层次结构的一种企业组织形式─—股份制企业集团相继组建。股份制企业集团是新型的社会经济细胞，企业集团在扩大经营规模，拓展生产，实现生产要素和专业化协作体系的优化组合，增强市场况争能力等方面显示了强大的生命力，它的出现和发展是必然趋势。以国有企业为主组建的企业集团是最有市场竞争能力的集团。 Accompanied by the rapid development of corporate shareholding system reform in our country, a form of corporate organization with multi-level structure--joint-stock enterprise groups have been formed one after another. The joint-stock enterprise group is a new type of social and economic cell. The enterprise group has shown a strong vitality in the expansion of the scale of operations, the expansion of production, the optimization and combination of production factors and specialized collaboration systems, and the emergence and development of its products. It is an inevitable trend. An enterprise group formed mainly of state-owned enterprises is the most competitive group in the market.
