摘　　要：采用随机前沿面生产函数法,考察1989—1999年全球石化行业及典型企业的技术效率,进行企业国际竞争力的比较,发现全球石化行业发展所经历的3个不同规模效应变化的阶段:规模报酬递减—规模报酬不变—规模报酬递增。这个结论与全球石化行业实际经历的3个典型阶段完全吻合,说明全球石化行业正处于不断发展中,而不是衰退趋势。同时研究中还发现,新的管理技术在行业和企业的发展中已经起到引擎作用,领先公司引导了整个行业发展轨迹。The technical efficiency in the important petrochemical companies during 1989-1999 was analyzed using a methodology of the stochastic frontier production function, with which the competitive edge of the companies was compared. It was found that the scale effect for the petrochemical companies could be described as 3 different modes: returns decreasing with scale, returns constant with scale, and returns increasing with scale, which was consistent with what the petrochemical industry in the world had experienced. This indicated that the global petrochemical industry is in developing, not decaying. It could be concluded from the research that the new management technology is an engine for the development of a company, the one with advanced management technology will lead the development of the industry.
