中文摘要：

本文运用现代经济学方法重新考察马克思主义政治经济学中的市场经济理论,深入阐述马克思主义政治经济学对固定资本内涵及其本质的分析,确立社会价值实现及经济危机产生的内在机制问题,进而确立了马克思主义政治经济学独特的投资成本补偿一价值实现的市场失灵分析框架,再次看到私人秩序与政府干预的重要性。因此,为了避免出现沉淀成本,需要采取各种制度或政策以补偿投资成本,使投资成本都能够得到及时补偿,不至于影响企业简单再生产过程。这样,结合现有西方经济学理论知识,尤其是交易成本、产权结构、委托代理以及政府宏观调控等理论,充分理解影响固定资本投资的各种因素,对政府干预市场做出新的理论解释和新的指导,关键在于加强沉淀成本与不确定性管理,对于当代中国马克思主义政治经济学发展具有重要的理论与现实意义。

英文摘要：

Sunk costs are conventionally defined by western economists as those costs that are not recoverable in the case of exit. Marx, however, focuses on the production process and asset depreciation within time horizon irrespective of exit from market. In terms of value realization or cost recov- ery Marx＇s sunk costs are defined as inability to realize in the market the full value of their product and the residual value of capital investment. Furthermore,We have found the adverse effect of sunk costs on the economic system,and leading to economic crisis. In order to avoid the economic crisis in market economy, government intervention is provided toward sunk costs and uncertainty management,including aggregate supply and demand policy, not only laissez-faire.
