基于环境约束的苏南模式转变有效性分析

Efficiency Analysis of Southern Jiangsu Model Transformation Based on Environmental Constraint

制度的有效性是相对的,制度的有效性可以从静态有效性和动态有效性两个方面来分析。静态有效性是在一定的制度安排下,产出尽可能的接近生产可能性曲线,而动态有效性是在通过更有效的使用现有投入的方式获得,即通过制度安排或技术提高要素的边际产出,使得生产可能性曲线向外扩展。因此,制度保障了输入要素的产出效率。同时,制度是在不断变革中趋于新的平衡。从纵向来看一个制度的变革是否有效,就必须观察其投入要素的产出相对效率有无改善。文章尝试采用DEA方法分析苏南模式制度变迁的有效性。分析的结论是从定量角度表明苏南模式转化的效率逐步显现,其动态效率的提升表现为包络面地向外扩张。

The efficiency of institution is relative, and the efficiency of institution could be analyzed from the two aspects： static efficiency and dynamic efficiency. In a certain institution, static efficiency means the output as close to the Production Possibilities Frontier （PPF） as posible. The dynamic efficiency re- fers to expand the PPF outward by using existing input factors more effectively, by means of new institu- tion arrangement or new technologies to improve the are productive that must depend on an efficient a new balance accompanied by constant change marginal output~ For an economy, the input elements system. At the same time, the institution tends to set up From longitudinal perspective, we must observe the out- put increase of the input elements when evaluating the efficiency of the system. This paper attempts to use method of Data Envelopment Analysis （DEA） to analyse efficiency of institution Conclusions from quantitative method reflect the efficiency of conversion ＂sunan mode＂ gradually appear. That the enve- lope face of output expands outward continuously means the upgrade of its dynamic effiency.
