Abstract:A decomposition into components of the overall technological change is carried out.The overall technological change is decomposed into the technological change,which consists of autonomous shift and shape-deformation in isoquants of production function over table,the scale economics or diseconomies,and the technological change,which is determined by marginal rates of substitution of factors,capital/labor ratio(capital intensity)and its changes.Under the assumption of constant returns to scale the mathematical framework reduces exactly to Solow's framework. The mathematical formula derived can be applied to measuring the overall technological change in its components.
Keywords:economic growth  technological change.
