Through theoretical analysis, this paper firstly discusses the inherent mechanism between tourism development and the industrial structure, then puts the low carbon economy growth into the tourism industry development and industrial structure upgrading interactive relationship under the framework, and draws a conclusion. On the basis of this, an empirical model (SEM) is constructed for the panel simultaneous equations between the three. Take China provincial data as samples, and dividing it into a whole, the eastern, the central and the western region respectively for empirical test, we get the following conclusions: on the whole, the development of the tourism industry and the upgrading of the industrial structure is to promote mutual relations between the two, and they also have positive effect on low carbon economy growth; the test results of the whole country and the eastern region past through the regression test; the interaction between tourism development and the upgrading of the industrial structure of the central region is not obvious, the upgrading of the industrial structure has not significant influence on the growth of low carbon economy; some regressions of the western region do not pass the test, but the interactive relationship between the development of tourism and the upgrading of the industrial structure is significant, and has a promoting effect on the growth of low carbon economy. The empirical results also confirm the theoretical analysis and hypotheses. The different regression results in the eastern, central and western region show that the development of China exists unbalanced spatial characteristics. Therefore, in the regional development policy-making, it need to both maintain global awareness and pay attention to regional differences in order to guarantee policies more scientific and comprehensive.
