| After entering the 21 st century,the world of scientific and technological innovation into the intensive active period,automation to accelerate the pace of the direction of digital,network and intelligent development,new technology,new industries and new models,a wide range of new products,profoundly affected the global science and technology innovation landscape,industry development pattern and the trend of economic development.Historical experience of the development of human society shows that every major change in economic form,often create and rely on new economic factors,in the past is given priority to with agricultural economy,land and labor is the core factor of promoting economic development,and with the development of the Internet industry,data gradually developed as the important factors of production,digital economy era has come.This paper focuses on big data development policy itself,the government since 2017 big data development policy research,analyzes the text characteristics of big data development policy and implementation status,help people to deepen the understanding and understanding of big data policy,also help to better find the problems existing in the development process and put forward optimization Suggestions.This paper makes the research more thorough and comprehensive from the two aspects of static text and dynamic execution,which enriches the relevant theoretical system of big data and also provides valuable reference for the development of big data policy.This paper analyzes the text of big data policy at the national level issued by the Chinese government in 2017-2022,Three-level coding by a policy tool,Then,the characteristics of China’s big data policy text are summarized and summarized;Based on the Smith model involved in the policy implementation process,And with the Smith model as the main analytical framework,Analyzed the relevant influencing factors of big data policy implementation in various provinces,And then to analyze the model results;Further,the ISM interpretation structure model is used for policy analysis;on this basis,Analyze the problems existing in the implementation process of big data policies in China,Then we put forward the countermeasures and suggestions to improve the implementation effect of big data policies;The future development of big data policy in China is also discussed. |
