The constitutional citation in judicial decisions can effectively respond to the functional demand for constitutional implementation at the social level,and further play the important role of constitution in the governance of China.By applying big data analysis,the overall distribution of constitutional citation cases can be clearly grasped.Through the typological summation,the constitutional citation methods of parties involved include enumeration,association,explanation and response,and the courts'responses to different citation methods mainly include not supporting,correcting,and approving the citation.Judicial practice shows that the constitutional citation of parties involved have the need to be responded,but the courts'response rate is relatively low.The courts'attention degree,standardization degree and responsiveness to the constitutional citation of parties involved should be further improved.Hence,principles of citation should be established,response situations should be clarified,training of citation should be conducted,and guidance documents and cases should be issued,so as to promote the standardized development of constitutional citation,and make it a traceable way of implementing the constitution.
