摘　　要：用永续盘存法测算资本存量依赖于投资信息的可得性,一旦投资信息缺失,永续盘存法便不可以直接用来测算资本存量,即使勉强使用,其测算结果的准确性和可信度便会大幅度降低。提出了两种测算资本存量的方法,即等资本—产量比法和哈罗德—多马模型法,弥补了永续盘存法的不足,扩展了其适用范围,并以海洋经济为例分别使用两种方法测算资本存量K,对测量结果进行对比,同时分析两种测量方法的适用性。Capital stock is a key indicator in research of economic growth, investment efficiency and TFP. We can＇t estimate capital stock without investment information, which hinders mentioned researches and reduces their accuracy and credibility. This paper puts forward two new methods to estimate the capital stock of economy, which are methods of equal-capital-output ratio and Harrod-Domar model, to make up deficiency of perpetual inventory method and expand its usability. This paper uses these two methods to estimate the capital stock of Chinese marine economy, compares the calculations, and analyses and compares the applicability of these two methods.
