摘 要: 利用中国零售业上市公司2002—2013年的统计资料,基于超越对数成本函数模型,运用似不相关回归对上市零售企业的规模经济效应进行测度。结果发现:国内上市零售企业整体存在一定的规模经济效应,并随时间发展效应增强,但2008年后出现了一定程度的规模过度扩张,从而导致规模经济效应增速放缓;行业内的规模经济效应出现显著的区域异化,东部沿海地区的零售企业规模扩张较快,从未出现过规模经济效应(即规模不经济),而中西部后发地区的零售企业规模经济效应相对显著;适中的产出规模更有利于规模经济效应的实现,零售业规模经济有赖于区域经济和居民消费水平、基础设施以及人力资源。 Using the data of Chinese retailing enterprises listed on the Shanghai and Shenzhen stock market during the years from 2002 to 2013,this research adopts the seemingly unrelated regression to measure the scale economy effect,w hich is based on trans-logarithm cost function model. The findings are as follow s: There is somew hat economies of scale in domestic listed retailers on the w hole,and the effect grow s w ith economic development. How ever,the scale of the listed retailers after 2008 has been over-extended to some event,w hich leads to a slow dow n in the grow th of economies of scale. The scale economy effect in the industry appears significant regional differentiation. Retail enterprises in eastern China don 't show any scale economy effect w ith their rapid scale expansion,w hile the effect is rather significant in the northern,middle and w estern areas. The economies of scale perform best w hen the output is in the middle of the range. The research show s that the realization of scale economy effect depends on the development of regional economy,the level of residents' consumption,and investment in infrastructure as w ell as the human resources.
