科学技术实现＠功能的方式社会上习惯于把科学和技术联在一起，统称为“科技”。实际二者既有密切联系♀，又有重要≡区别。科学解〇决理论问题，技术解在招标投标法中规↓定，招标人可以自行招标，也可以委托招标代理机构办理♀招标事项。这两种方法并存是★符合我国实际情况的，也适应∮了招标人实际需要，至于采用〓哪一种方法则由招标人依照法律上的要求自行▲决定，招标人有自主抉择的权利，但是又不是无条件地进行抉择。因此＠ 在法律中明确，只有招标人具有编制招标文件和组织评标能力↘的，才可以自行办理招标事宜。在立法中还考虑到应当防止自行招标中可能有的弊病，保证招标质量，因此规定，依法必须进行招标的项目，招标人自行办理招标事宜的，应当向有关行政监〖督部门备案。According to the Law on Tendering and Bidding, a tenderer may invite bids by himself or entrust a tendering agency to handle tendering matters. The coexistence of these two methods is in line with the actual situation of our country, and also adapts to the actual needs of the tenderer. As for which method to adopt, the tenderer shall decide by himself according to the requirements of law. The tenderer has the right to make his own choice, but it is not unconditional. Therefore, it is clear in the law that only if the tenderer has the ability to compile the tender documents and organize the evaluation of tenders, he can handle the tender matters by himself. In the legislation, it is also considered that the possible disadvantages in self-bidding should be prevented and the quality of bidding should be guaranteed. Therefore, it is stipulated that if a project must be tendered according to law, the bidder should file the matter with the relevant administrative supervision department.
