从介绍评价电力工业科技进步贡献率的方法──生产函数法入手，对该方法（索落余值法）应用在“九五”期间的电力工业科技进步评价时所涉及的各经济量的变化趋势进行了分析预测，讨论了这期间提高电力工业科技进步的途径，得到如下结论：若使电力工业“九五”期间的科技进步贡献率Ｅａ值较“八五”期间有所提高，此期间的电力科技投入不能仅仅维持在“八五”的增长水平，必须使之大幅度提高。同时，在目前较可行的前提下，提出了将电力工业产值的１％作为本行业科研投入的建议。
Starting from the method of production function that describes the evaluation of the contribution rate of scientific and technological progress in the power industry, the application of this method (resolving residual value method) to the changes in various economic quantities involved in the scientific and technological progress evaluation of the power industry during the Ninth Five-Year Plan period The trend was analyzed and forecasted, and the ways to improve the scientific and technological progress of the power industry during this period were discussed. The following conclusions were reached: If the Ea value of the technological progress contribution during the “Ninth Five-Year Plan” period of the power industry is increased compared with the period of the Eighth Five-Year Plan, during this period The investment in electric power technology can not only be maintained at the growth level of the “Eighth Five-Year Plan”, but must be greatly increased. At the same time, under the premise of being more feasible at present, it puts forward 1% of the output value of the power industry as the research input of the industry.
