The Research On The Application Of Evidence-based Decision-making Under The Background Of Big Data

Policy making is a complex process. The change from empirical decision making to evidence-based policy making is a major trend practiced by the government around the world at present. They are all trying to make the most powerful evidence become the cornerstone of the public policy making. Based on evidence-based medicine, the essence of evidence-based policy making is such a kind of decision which is made based on the evidence. With the arrival of the era of Big Data, it brings a new direction of development for the public policy making by the characteristics, policy making thought and decision making frame of big data. It is possible that making the application of big data into evidence-based policy making due to its own characteristics of big data and the practical demand of evidence-based policy making.Big data not only makes up the deficiencies of evidence collection, production and evaluation of evidence-based policy making and helps it develop toward the direction of automation, but what is the most important is that big data technology is a kind of extraction techniques featured by automation, which can collect high value data and establish the high precision analysis model for policy making, so as to so as to greatly improve the efficiency of evidence analysis and decision support of evidence-based policy making and promote the widely application and popularization of evidence-based decision-making in a variety of fields of policy making. The era of big data and big data have a great significance and impact on the development of evidence-based policy making. The application of evidence-based policy making in public policy making has become a new trend under the support and promotion of Big data technology.However, the lack of evidence-based consciousness, the restriction of the system and mechanism, the reliability of the evidence and the data itself, and the shortage of talents all hinder the application of evidence-based policy making in our country. Therefore, the only way to realize the evidence-based policy making based on big data and achieve scientification, rationalization, democratization and intelligence of policy making is to make breakthrough and changes in the system level, the level of consciousness, the cultivation of professional talents and legal dimensions in our country.
