An empirical analysis of dialect and regional economic growth based on OLS regression model

There is a relatively new economic growth theory that culture is a deeper force to explain economic growth. This paper will establish an economic growth model based on Solow model, and discuss the economic growth of multi-ethnic areas from the perspective of language economics. On the basis of literature research, this paper first puts forward the conjecture that dialect diversity has a negative impact on the economic income level of multi-ethnic areas. In order to verify this conjecture, this paper selects Xiaojin County, Danba County, Puge county and Butuo County of Sichuan Province as the investigation objects. After screening more than 200 effective data, the least square linear regression model is used to carry out empirical analysis. Through White Heteroscedasticity Test and WLS Heteroscedasticity Test, the hypothesis that dialect diversity has a negative impact on economic income level in multi-ethnic areas is verified.
