The exploration of the technology for the old age care from the perspective of the technology and the market can provide a theoretical support for the effective layout of the technology in the future and rely on technological innovation to deal with the aging problem. First of all, from the perspective of the technology, using Incopat patent database as the data source, using the S-curve method to determine the technology life cycle, and on this basis, using Atot to build a dynamic evolution model of the theme, to study the development status of China's old age care technology; secondly, from the perspective of the market, using the text mining to identify hot topics of the knowledge data, to determine the development trend of old age care technology; finally, from the perspective of the technology and the market, this paper analyzes the existing problems in its development, and puts forward countermeasures and suggestions. China's old age care technology is in the growth period of the technology development; the technology and the development are mainly focused on the mobile devices, the action assistance, the home and the nursing; from the perspective of the technology and the market, it is found that the investment in the home technology and development is relatively small, but the demand is high, and the future enterprises should pay special attention to the home technology, and make a proper technology layout.
