英文摘要：

Sustainable innovation capacity, as one of hot research topics at present, is the key factor of sustainable development and economic growth for small and middle-sized technology-based enterprises. In this paper, we review the basic theory of sustainable innovation capacity, then construct evaluation index system of sustainable innovation capacity for small and middle-sized technology- based enterprises. Moreover, we propose improved DFQFD model based on QFD model, which provides the important theoretical basis for the evaluation of sustainable innovation capacity of small and middle-sized technology-based enterprise. The results show that our improved DFQFD model for sustainable innovation ability evaluation is effective and feasible. Besides, our research provides the refer- ence and decision basis for small and middle-sized technology-based enterprises to improve sustainable innovation capacity.
