沉淀成本与资源型城市转型分析

本文应用一个简单的投资模型，从经济性沉淀成本和社会性沉淀成本角度分析了资源型城市转型的障碍并提出了相关的政策建议。模型分析表明，沉淀成本与信息不完全的结合会在很大程度上扭曲资源配置，导致产业结构刚性，降低经济效率和福利水平。因而资源型城市转型的基本政策处方，是补偿经济性沉淀成本和社会性沉淀成本，促进各类生产要素的充分流动，以利于资源型城市投资主体的自由退出和发展接续产业。

Sunk Costs and Barriers & Solution to Resource-based Urban Transition

The paper is to analyze the resource-based urban transition in terms of economic and social sunk costs.Based on the investment model with sunk costs,we show that both sunk costs have a great adverse effect on the resource-based urban transition.Because of the existence of great sunk costs in the urban,they adversely influence the investment direction and speed of the transition.In principle we provide the solutions to the urban transition,that is,reduce and recover the amounts of both sunk costs,and increase in the mobility degree of assets.
