珠江三角洲中心城市经济增长中生产要素作用初探

Effect of Production Factors in the Economic Growth of Core Cities of the Pearl River Delta

劳动力、资本和科学技术并称生产的三大要素.本文以珠江三角洲三大中心城市——广州、深圳、香港为研究研究,运用Cobb-Douglas生产函数,对1981—1994年以科技进步要素为主的三大生产要素在三市经济增长中的作用进行了探讨,比较了三市劳动力的固定资产装备率和劳动生产率,估计了三市产出对劳动力投入与资本投入的弹性参数,测算了技术进步率及科技进步在经济增长中所占的比重.

Labor force, capital and technology are among the key factors of production. With Guangzhou, Shenzhen and Hongkong, the three core cities of the Pearl River Delta, as the cases, by applying the Cobb-Douglas production function, this paper probes into the role that the above-mentioned production factors play in the urban economic growth during the period from 1981 to 1994, with emphasis laid on the effect of technologies. The level of fixed assets equipment and productivity of labor forces are compared among the cases,the elasticity coefficient of output to inputs of labor and capital are estimated, and the rate of technological progress as well as its weight in the economic growth are measured.
