摘　　要：在非常数规模报酬的超越对数联合成本函数的基础上,引入科技资本、教育水平和市场化率三个代表技术进步的指标变量,运用微观经济理论分析和统计指数技术方法,分离出规模报酬因素和纯技术进步因素,建立了产出数量指数与投入数量指数及技术进步指标指数之间的关系模型。利用我国20个行业的投入产出数据,实证证明了行业发展存在明显的规模报酬效应,并且在所选的技术进步三因素中,教育指标是主导因素,市场化率指标的影响较小,而科技资本指标对成本的节约是有负面影响的。In this paper, the authors base on the Non-constant Returns to Scale Translog Joint Cost Function and introduce the three technical progress indexes of education level, science technology level and marketing rate level. The authors set up the relationship model of output index, input index and technical progress index through the analysis of micro-economic theory and the technical method of statistical index, and then get the returns to scale and technical progress. Through the empirical analysis using the input-output data of 20 industries, the conclusion is that China＇s industries have obvious effects of returns to scale, and among the factors of technical progress, education is the dominant factor, marketing rate has less affected, while technical capital is negative to the cost saving.
