摘要 由于收集数据时很难获取投入要素的价格信息,因此在实际分析生产效率时很难使用分配效率这一重要指标.本文在假设经济无效完全是由技术无效造成的前提下,利用Cobb-Douglas生产函数与成本函数的自对偶性,通过分析Cobb-Douglas型技术效率与经济效率之间的关系,得到了分配效率的测算公式.这个测算公式与投入价格无关,仅仅是技术效率的一个函数.对我国20个行业分配效率和技术效率的测算结果表明:我国工业各部门的资源配置能力相对较强,但获取最大产出的能力较弱. The difficulty in observing the prices of inputs in practice prevented investigators from evaluating allocative efficiency of each firm. If only the technical inefficiency leads to economic inefficiency, the explicit expression of economic efficiency and allocative efficiency can be obtained by the self - dual property of Cobb - Douglas production function. Moreover, this allocative efficiency, which is the function of technical efficiency, can be estimated without price information. The allocative efficiency and technical efficiency measured by the proposed method for 20 industries show that the ability of allocating resources is much stronger than that of obtaining maximum outputs in China.
