Abstract: The concept of scitech fuzzes the boundaries of science and technology， which has many defects: firstly， scitech mainly refers to technology and rarely to science， doing the negligence to the development of scientific spirit; secondly， the concept of scitech involves the potential ethical risks of technology; thirdly， it is hard to set and implement relevant policies due to the fuzziness of scitech. From the postmodern perspective of epistemology， scitech represents the development trend of contemporary scientific knowledge， which implicates many traits of postmodern science: organicness， ecology， entirety， nonlinearity， valuerelevance， locality and others. Hence， a postmodern thinking of the concept of scitech is important in establishing a real scientific spirit， creating a good academic environment， and ensuring a harmonious development of science， technology and society.

Key words: scitech, science and technology, postmodern science, epistemology
