交易费用是公共部门运行中一种相当突出也相当复杂的经济现象。公共部门的运行既有可使交易费用降低的一面,也有会使交易费用“居高不下”的一面。这种“矛盾”现象,就使对公共部门交易费用的研究具有明显的理论和现实意义。在我国当前进行的公共财政建设中,如何合理看待、把握交易费用问题,如何控制好交易费用的“度”,就是个值得重视的问题。 Transaction costs are a rather prominent and rather complex economic phenomenon in the operation of the public sector. The operation of the public sector is accompanied by a reduction in the transaction costs and a “high” transaction cost. This phenomenon of “contradictions” makes the study on the transaction costs of the public sector a clear theoretical and practical significance. In the current public finance construction in our country, it is a problem worth paying attention to how to reasonably treat and grasp the issue of transaction costs and how to control the “degree” of transaction costs.
