Abstract: Abstract:It is hopeful for experimental economics to relax two key restricts existed in the developing of econometrics from both the basic hypothesis of economic theory and data, because there are some characters of controllable, repeatable and observable with experimental economics. In this paper, from the perspective of experimental economics, it is explored for us how to acquire and deal with better economic datum, in order to play down the negative effect on econometric analysis from interaction, co-linearity and concealed function of economic datum. It is a new way to promote the quality of economic data and to make economic analysis more effective, especially to the Chinese economy
