我国政府采购制度改革实行10多年来,每年政府采购实际支出与预算相比,资金节约率为10%左右。财政资金的节约是由政府采购制度的改革带来的吗?采购制度的一些重要变化的影响分别如何?对于这些问题,本文利用我国2001—2004年各省的面板数据进行分析。主要分析集中采购比率、公开招标比率和政府直接支付比率的变化对财政资金节约的影响。分析结果表明,各比率变化的影响大多数为正。即提高各比率会促进财政资金的节约。但是,集中采购比率等过大会增加管理采购成本,给财政资金的节约带来负面影响。
Over the past 10 years since the implementation of the government procurement system reform in our country, the actual annual expenditure on government procurement has been about 10% compared with the budget. What is the impact of some important changes in the procurement system? For these issues, this paper analyzes the panel data of each province in China in 2001-2004. The main analysis of centralized purchasing ratio, open tender ratio and direct government payment rate changes on the financial savings. The analysis shows that most of the impact of the rate changes is positive. That is, increasing the ratios will promote savings in financial resources. However, over-generalization of procurement ratios, etc., will increase the management procurement costs and negatively affect the financial savings.
