新制度经济学与混合制管理模式

交易成本经济学和代理理论是新制度经济学的两个重要理论。以交易成本为主要研究对象，交易成本经济学指出，根据交易的性质选择不同的管理模式能使交易费用最小化，提高经济活动的效率。代理理论则从研究激励成本的角度出发．探讨如何设计一套有效的激励机制去降低交易成本、提高经济效率。综合两种理论的主要观点，本文构建了一个以激励为度量的三维模型去研究计划、混合制和市场三种管理模式，强调混合制管理模式既结合了计划及市场模式的优点，又克服了两者的缺点，是一种更为有效的管理模式。

New Institutional Economics and Hybrid Governance

Based on the analysis of incentives in principal-agent theory, a more generalised three-dimensional governance model is established in this article to analyse market, hybrid and hierarchy governance in relation to three incentive instruments in the public management. Combining both the advantages of market and hierarchical governance, hybrid governance uses three incentive methods to control cheating problems in market governance and to overcome incentive and shirking problems in hierarchical governance. Therefore, under certain circumstances, hybrid governance can organise transactions in a much more efficient way than market governance and hierarchical governance.
