Abstract: Contribution rate of technological development is one of the important indicators for quantitative evaluation of the technological development level of an enterprise. Since the "C-D production functions" and the "Solow residua" method are limited in selection of production factors and estimation of parameters, the calculated results are not in line with the actual conditions of the enterprise. Therefore, many economists are studying new calculation methods and models. Take oil and gas pipeline transportation enterprises for example. Based on the six-element production theory of modern economics and the principle of scale economics and take the production and operation constraints into account, the model is added with the key objective elements that restrict development and production of the enterprise. The theoretical errors of the original method are explained according to the "bucket theory" and "crowding theory of factors of production", while the elasticity coefficient estimation method is proposed on the basis of the new elements to improve the growth function model. It can compensate for the shortcomings of traditional methods in the enterprise applications, and make the results of quantitative assessment of technological development closer to the actual conditions.
