摘　　要：本文使用差分方程组分析了创新绩效、R&D资本存量与吸收能力的增长路径。分析结果表明:当R&D资本存量的现值比率与上期创新绩效对当期创新绩效的总贡献率之和小于1时,创新绩效、R&D资本存量与吸收能力的增长受到限制,且增长速率越来越小;当R&D资本存量的现值比率与上期创新绩效对当期创新绩效的总贡献率之和大于1时,创新绩效、R&D资本存量与吸收能力的增长不受限制,且增长速率越来越大。此外,折旧率、其他因素共同作用所产生的创新绩效、同一期的R&D资本存量对吸收能力的边际贡献与同一期的R&D资本存量对创新绩效的总贡献率对这三者的增长速率也有影响。The growth paths of innovation performance, stock of R＆D capital, and absorptive capacity are analyzed using the system of difference equations. The results indicate that in the event of the sum of present value rate of stock of R＆D capital and total contribution rate of innovation performance in the prior period to that in current period is less than one, growths of innovation performance, stock of R＆D capital, and absorptive capacity are under restrictions, and speeds of their growths are getting smaller and smaller. In the event of the sum of present value rate of stock of R＆D capital and total contribution rate of innovation per- formance in prior period to that in current period is greater than one, growths of innovation performance, stock of R＆D capital, and absorptive capacity are unconstrained, and speeds of their growths are getting bigger and bigger. Furthermore, the rate of de- preciation, innovation performance from other elements, contribution margin of stock of R＆D capital for absorptive capacity in the same term and total contribution rate of stock of R＆D capital for innovation performance in the same term also have influence on the speeds of their growths.
