<p align="left">希克斯的中性型技术进步，是指使资本边际生产力对劳动边际生产力比率保持不变的技术进步，或者说技术进步并没有改变资本的边际产量对劳动的边际产量之间的比率。在图3—1中，纵坐标Y/L代表每个劳动力的平均产出量，横坐标K／L代表每单位劳动平均使用的资本量。OP为没有发生技术进步时的生产函数曲线，OP’代表发生技术进步后的生产函数曲线。在这里，OP和 OP’ 为假定生产函数的曲线，都具有资本边际生产力递减的特性，即随着每单位劳动配备资本量的增加，每增加1单位的资本所增加的产量是递减的，因<br/></p><p><span lang="EN-US"><shapetype id="_x0000_t75" coordsize="21600,21600" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f" opreferrelative="t" ospt="75"></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype> <span lang="EN-US"><shapetype id="_x0000_t75" coordsize="21600,21600" path="m@4@5l@4@11@9@11@9@5xe" filled="f" stroked="f" opreferrelative="t" ospt="75"></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype><shapetype></shapetype>
