论高科技知识创新的报酬递增与递减特点——兼论“知识经济条件下报酬持续递增规律的有条件性”

On the Characteristic of lncreasing or Decreasing Return of Hi-technology ——and Discussing the Prerequisite of the lncreasing Return of Knowledge-based Economy

知识既是内生变量，又是外生变量，这是理解高科技知识报酬递增与递减特点的基础。高科技知识的报酬递增与递减都有可能，这是由高科技知识创新系统的各生产要素的供给有限性和该系统的自组织能力的有限性决定的。在一定条件下，高科技知识创新存在一个阈值，每次高科技知识大的突破，都是系统进入一个新的发展周期，在这个新的发展周期有比前一个周期更高的阈值。要使高科技知识在整个发展过程保持持续报酬递增，必须加速创新和整合，使之在未到达报酬递减前就进入下一个周期的递增阶段：知识经济时代高科技知识创新的报酬保持持续递增是有可能的。

Knowledge is not only an endogenous variable, but also an exogenous variable, which is the base to understand the characteristic of the increasing or decreasing return of hi-tochnology in knowlodgc-bascd cconomy. The incrcasing of deercasing rcturn of hi-technology is all possible in a developing period, which results from the limitation of the factors' supply of system and its capital of self-organization. Every period of knowledge development has a ceiling limitation. In order to keep a sustainable increasing return, creating and confirming are necessary, which make it possible to enter into a new increasing return stage of the new developing period having a higher ceiling limitation.
