城镇化进程中产业结构效益的优化——以重庆市为例

Optimization of Industrial Structure Benefit in the Process of Urbanization——A Case Study of Chongqing Municipality

产业结构的优化升级是推进城镇化和社会经济发展的重要课题,在测度重庆市产业结构效益与城镇化质量协调发展水平的基础上,依据响应面法最优响应因子的提取条件,找出最优区域的原始值并借助Design Expert8.0软件进行实验优化.研究表明:重庆市提高产业结构效益亟需做到:1努力提升三次产业比较劳动生产率;2控制三次产业的产业结构偏离度并使之越来越趋近于零,第一产业由正趋向于零,二、三产业由负趋向于零;3降低第一产业产业贡献率,注重提高二、三产业的产业贡献率.

Optimizing and upgrading industrial structure is an important issue in promoting urbanization and social and economic growth. In a study reported in this paper, the coordinated development level between industrial structure and urbanization quality in Chongqing Municipality was measured, the original values in the optimal region were calculated according to the extract conditions of the optimal response factors of the response surface methodology （RSM）, and then an optimization experiment was made by virtue of the software Design Expert 8.0. The results indicated that for the sake of improving industrial structure benefit of Chongqing, great efforts should be made to improve the comparative labor productivity of the tertiary industry; to control the structure warp coefficient of the tertiary industry and make it approach zero, make the structure warp coefficient of the primary industry move from positive to zero and make that of the secondary and tertiary industries move from negative to zero; and to reduce the contribution rate of the primary industry and improve that of the secondary and tertiary industries.
