技术引进是一项复杂的、涉及面广、技术性强的管理过程。技术引进项目可包括技术、设备、仪器和机器等。一般技术引进程序包括申请审批、筹集资金、技术论证和可行性评价等。经济效益是技术引进论证的重要原则之一。目前采用的方法不少,如费用效率、投资回收期法、寿命周期费用换算法、受益指数评价法和线性 Technology introduction is a complex, wide-ranging and technically-strong management process. Technology introduction projects can include technologies, equipment, instruments and machines. General technology introduction procedures include application for examination and approval, raising funds, technical demonstration and feasibility evaluation. Economic efficiency is one of the important principles of technology introduction and demonstration. There are many methods currently used, such as cost efficiency, payback period method, life-cycle cost change algorithm, benefit index evaluation method and linearity.
