摘要
当今社会，科学技术日新月异，飞速发展，已经成为推动经济增长和社会进步的核心力量，不仅改变着人们的生活方式，也对政治、文化和经济发展方式产生深远的影响。自2014年李克强总理提出“大众创业、万众创新”以来，更是激发了亿万群众智慧和创造力。科技创新成果不断提升人们的生活质量，科技创新精神不断渗透人们的生活方式和思维方法，使我们生存的这个时代，与科技创新的联系越来越紧密。而技术的发展并不是单独存在的，是在复杂的社会中创新发展，受到各种因素的制约和影响，不同国家和地区、不同时代和环境对技术创新发展都会产生不可忽视的影响。因此，对技术创新及其发展进行多维度的、综合全面的评价，对把握研发热点、洞察未来趋势具有重要意义。
目前国内有关技术创新的发展研究的研究尚停留在技术创新者的创新能力、各类技术的比较研究等比较片面而具体的方向上，尚未对技术创新有一个比较宏观而全面的研究模型，从而无法对我国技术创新进行整体把握与动态跟踪。而国外的技术创新研究模型较为成熟，可以引进作为参考，但仍然有一些不足之处。
本文在原技术交付系统（Technology Delivery System，TDS）模型的基础上，结合技术生命周期理论，增加时间和空间维度，提出动态TDS模型。动态TDS模型通过以下五个步骤构建：（1）划分技术创新周期；（2）确定政策环境和资金环境；（3）识别创新主体及其合作关系网络；（4）分析技术创新的热
点地区变化；（5）探究技术创新的热点主题演变。在此基础上，以中国医疗影像技术为例，应用动态TDS模型对其技术创新发展进行研究，通过社会网络分析、关键词共现分析等方法，对技术创新不同阶段的科研文献、专利文件、政策文件等数据的分析，深入了解技术创新发展，明确各个阶段的宏观政策环境和资金环境、技术创新主体的合作关系、创新热点地区和主题的变化，描绘市场前景并评估对技术变革和社会发展的潜在深远影响，旨在促进技术研发与技术应用的双向良性发展，并为政府和行业的决策提供有益参考。本研究对中国医疗影像技术的实证分析主要有以下几个结论：
（1）政府的政策引导和资金支持在中国医疗影像技术发展的技术开发阶段和技术应用阶段都十分匮乏，应用开发阶段开始，在政策的积极促进和基金项目的支持推动下，中国医疗影像技术创新呈爆发式增长。
（2）中国医疗影像技术的创新主体之间的合作关系，各阶段都有各自不同的特点，技术开发阶段、技术应用阶段、应用开发阶段、应用增长阶段分别呈现出单位内部个人合作、区域性合作、跨集团跨区域合作、跨集团跨区域跨创新主体类型合作的特点，但是合作关系并不紧密。创新主体类型从研究所和医院逐渐转变为公司和高等院校。
（3）中国医疗影像技术的创新热点地区起始于东部和东北地区，呈现出逐渐南移，并向中西部扩散的特点，目前核心热点地区基本稳定在广东省。
（4）超声诊断技术因其安全性、实时性等特点，从技术开发阶段就受到广泛关注。而磁共振成像、CT等技术，从技术应用阶段开始，研究热度居高不下。技术开发阶段和技术应用阶段热点主题呈现出多元化演变的趋势，应用开发阶段和应用增长阶段热点主题则向纵深化方向发展，衍生出的超声弹性成像、彩色多普勒超声、弥散加权成像、多层螺旋CT等新兴技术的研究愈发受到关注。
（5）在结合应用增长阶段医疗影像技术关键词共现图谱、政策环境和相关产业报告的基础上，医疗影像技术与人工智能技术相结合必将是一个新焦点新趋势。依托强大的深度学习和图像识别技术，人工智能技术将有利于解决对医疗影像大数据进行人工处理时存在的问题，大幅度提高医疗影像数据分析的效率和准确性，在能够缓解医护人员的压力的同时，也能提高诊断和治疗的效率和准确率。标准化数据难获取，以及影像诊断模型的训练仅停留在对影像图像的识别和分析上，是目前人工智能与影像技术相结合的两大瓶颈。
酒英文综上所述，本文构建了一个综合全面的技术创新研究框架，为技术创新的理论发展和实践应用提供了更为整体和动态的分析视角，对技术创新发展的脉络进行梳理，探讨技术创新的规律和特点，以及技术创新与社会、经济的关系，可以为相关从业人员的工作和研究提供帮助，满足技术创新的管理需求，从而提升技术创新工作的效率，同时也可以为政府制定相关政策提供有益参考。

revenge第一季Abstract
integrationWith the rapid development of science and technology in today's society,it has become a core force to promote economic growth and social progress,not only changing people's lifestyles,but also having a profound impact on political,cultural and economic development methods.Ever since Premier Li Keqiang propod"Mass entrepreneurship and innovation"in2014,it has inspired the wisdom and creativity of hundreds of millions of people.The achievements of scientific and technological innovation constantly improve people's quality of life,and the spirit of scientific and technological innovation constantly permeates people's way of life and way of thinking,which makes our survival era more and more cloly linked with scientific and technological innovation.However,the development of technology does not exist alone.Technology is innovated and developed in a complex society,which is restricted and influenced by various factors.Different countries and regions, different times and environments will have a significant impact on the development of technology innovation.Therefore,the multi-dimensional and comprehensive evaluation of technological innovation and its development is of great significance to grasp the rearch and development hotspot and insight into the future trend.
At prent,the rearch on the evaluation of technological innovation in China still stays in the one-si
ded and specific direction,such as the innovation ability of technological innovators and the comparative rearch of various technologies.There is not a relatively macro and comprehensive model for the evaluation of technological innovation,so it is impossible to grasp and track the overall technological innovation in China.The evaluation model of technological innovation in foreign countries is relatively mature,which can be introduced as a reference,but there are still some shortcomings.
Bad on the original technology delivery system(TDS)model,combined with the technology life cycle theory,this paper adds time and space dimensions to build a dynamic TDS model.The dynamic TDS model is built in the following five steps:(1)divide the technological innovation cycle;(2)determine the policy environment and economic environment;(3)identify the main contributors and their cooperative networks;(4)analyze the changes in hot spots of technological innovation;(5)explore the evolution of hot topics of technological innovation.On this basis,taking Chine medical imaging technology as an example,the dynamic TDS model is applied to evaluate its technological innovation and development.Through social network analysis,keyword co-occurrence analysis and other methods,this paper analyzes scientific rearch documents,patent documents,policy

documents and other data in different stages,and deeply understands the development of technological innovation.Taking China's medical imaging technology as an example,this paper defines the macro policy environment and financial environment,the cooperation relationship of the main participants,the changes of innovation hot spots and themes of each stage,and describes the market prospect and evaluates the potential far-reaching impact on technological change and social development,aiming to promote the two-way benign development of technology rearch and development and technology application,and to provide uful reference for the decision-making of the government and industry.The main conclusions of this study are as follows:
(1)The government's policy guidance and financial support are very scarce in the technology development stage and technology application stage of China's medical imaging technology development.From the stage of application development,with the active promotion of policies and the support of fund projects,the innovation of medical imaging technology in China has exploded.
umbrella什么意思(2)The cooperative relationship between the main contributors of medical imaging technology innovation in China has different characteristics in different stages.The cooperative relationship among the main contributors of medical imaging technology innovation in China shows the characteristics of individual cooperation,regional cooperation, cross group and regional cooperation

and cross group,regional and contributors’type in the stages of technology development,technology application,application development and application growth,but the partnership is not clo.The types of main contributors gradually changed from magazines and hospitals to companies and universities.
(3)China's medical imaging technology innovation hotspots started in the east and northeast,showing a gradual shift to the south and spread to the central and western regions. At prent,the core hotspots are basically stable in Guangdong Province.
(4)Becau of its curity,real-time and other characteristics,ultrasound diagnosis technology has been widely concerned from the stage of technology development.From the stage of technology application,magnetic resonance imaging,CT and other technologies remain heated topics.The hot topics in the technology development and technology application stages show a trend of diversified evolution,while the hot topics in the application development and application growth stages tend to deepen in the longitudinal direction,and the rearch on emerging technologies such as ultrasonic elastic imaging, color Doppler ultrasound,diffusion-weighted imaging,multi-slice spiral CT has attracted more and more attention.

policy environment and relevant industry reports,the combination of medical imaging technology and artificial intelligence technology will be a new focus and new trend.Relying on powerful image recognition and deep learning technology,artificial intelligence will solve the problems in the artificial processing of medical image big data,greatly improve the efficiency and accuracy of data analysis,reduce the pressure of doctors,and improve the efficiency and accuracy of diagnosis and treatment.Standardized data is difficult to obtain, and the training of image diagnosis model only stays in the recognition and analysis of image,which are the two bottlenecks of the combination of artificial intelligence and image technology.
In conclusion,this paper constructs a comprehensive rearch framework of technology innovation evaluation,which provides a more holistic and dynamic perspective for the theoretical development and practical application of technology innovation evaluation. Combing the development of technological innovation,discussing the laws and characteristics of technological innovation,and the relationship between technological innovation and society,economy,can provide help for the work and rearch of relevant practitioners,meet the management needs of technological innovation,so as to improve the efficiency of technological innovation,and also provide uful reference for the government to formulate relevant policies.
