摘要
产业集聚经济效应是衡量地区经济发展规模与质量的体现.作者运用不变替代弹性生产函数,定量测算成渝经济区部分地区工业集聚经济效应.研究结果表明,1990-2010年,13个研究地区中,工业集聚经济效应不显著,呈现无规律变化,总体表现出规模不经济.而且,绝大多数地区没有工业企业集聚,没有享受到内部集聚经济和区位集聚经济,但多数地区产生了城市集聚经济,即存在初步的产业协作.
The industrial agglomeration effect reflects the scale and quality of the regional economic development. Based on the constant elasticity of substitution production function（ CES production function） , this paper is sup- posed to make an empirical result to reveal the effects （and its＇ changes） iof industrial agglomeration in 13 cities of Chengdu-Chongqing Economic Zone since 1990s. The results show that there is no apparent tendency in the chan- ges of industrial agglomeration effects from 1990 to 2010. Of all the 13 cities, only 3 cities（ including Leshan, Suining, Guang＇an） get internal economies of scale, and 3 cities（including Neijiang, Luzhou, Suining） get location economy, but 9 cities （ including Chengdu, Mianyang, Deyang, Yibing, Zigong, Leshan, Nanchong, Dazhou, Guang＇an） get urbanization economy. What＇s more, there are obvious location economie effects in Neijiang, Luzhou, Suining, especially in Neijiang. As to the internal economy of scale, there is no apparent agglomeration effect in each of the 13 cities. Though 9 cities get urbanization eeonomy, the empirical results show that the effect is not obvious. Of all the cities, Chongqing gets none of the internal economy of scale, location economy, and ur- banization economy. As for the government, they tend to invest money to the enterprises whieh are in a large scale. While for the preference of the enterprises, they select the best location for their economic development. It makes the scale of enterprises become larger. For the problems in the development of regional economy now, this paper will give some advises to solve them. For example, we should make a particular plan for each city, and give some preferential policy to the middle and small-sized enterprises. It makes the enterprises have a profitable scale, and enhances the agglomeration effects.
