中国养老科技的发展

 从技术角度，以Incopat专利数据库为数据源，利用S曲线法确定技术生命周期，并利用AToT构建主题动态演化模型，研究中国养老科技领域的发展现状；从市场角度，采用文本挖掘对知乎数据进行热点话题识别，确定养老科技领域的发展趋势；从技术-市场角度相结合，分析其发展中存在的问题，并提出对策建议。中国养老科技领域正处于技术发展的成长期；技术研发主要集中在移动设备类、行动辅助类、居家类和护理类；从技术-市场视角下，发现居家类技术研发投入相对较少，但用户关注度较高，未来企业应该特别关注居家类技术，在此技术领域进行技术布局。

The development of the science and technology of old age care in China from the perspective of supply and demand

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.
