On this basis, this paper theoretical and empirical aspects of the impact on economic growth in the new urbanization and mechanism specific role was overall analysis. Theoretical analysis shows that consumption of new urbanization can change Chanyejiegou upgrade urban-rural income gap and increasing the supply of public services and other four mechanisms to promote overall economic growth. However, their specific roles are significantly different path. Increase in consumption will be able to contribute directly to economic growth, Chanyejiegou optimize urban-rural income gap and increase the impact of public services for economic growth may be nonlinear. But no matter what kind of mechanism, the new town will have a positive role in promoting economic growth theory. The estimation results of further time series model and panel data model is verified this theoretical proposition. On the one hand, to each other between the new urbanization and economic growth Granger causes, and new urbanization impact on economic growth is greater than the impact of economic growth for the new urbanization of lag and a lag of four new urbanization were able to significantly promoting growth, lagged economic growth an impact on the new urbanization is not significant; on the other hand, after the addition of the relevant control variables, panel data estimation results indicate that the new urbanization is indeed a major cause of economic growth, and this kind of active role in promoting a significant difference in time and space. Jutilaiyue, the new town to promote economic growth in the eastern part of the most significant, followed by the central region, the western region the minimum. At the same time, over time, new urbanization for economic growth presents an inverted U-shape changes in a downward trend after an initial increase. <br>Subsequently, the influence of four paper the mechanism of action of the new economic growth of urbanization has been Xitongfenxi, and this is where the major innovation of this paper.

On this basis, this paper makes a general analysis of the impact of the new urbanization on economic growth and its specific mechanism from both theoretical and empirical aspects. The results of the theoretical analysis show that the new type of urbanization can promote the overall economic growth through four mechanisms: consumption change, industrial structure upgrading, narrowing of urban and rural income gap and increasing public service supply. However, there are significant differences in its specific path of action. Increased consumption will directly promote economic growth, while the impact of industrial restructuring, narrowing of urban-rural income gap and increased public service supply on economic growth may be non-linear. But no matter which mechanism, the new urbanization can theoretically promote economic growth. The estimation results of the further time series model and panel data model validate this theoretical proposition. On the one hand, the difference between the new urbanization and economic growth is the Reason of Granger, and the influence of the new urbanization on economic growth is greater than that of the economic growth on the new urbanization, and the new urbanization, which is lagging one period and the lag of four periods, can significantly promote the growth. On the other hand, the impact of economic growth in the first period of lag on the new urbanization is not significant, on the other hand, after adding the relevant control variables, the estimation results of the panel data show that the new urbanization is indeed an important cause of economic growth, and this positive role of promoting the differences between time and space. Specifically, the new urbanization for the economic growth of the eastern region is the most obvious, the central region is second to the western region is the smallest. At the same time, with the passage of time, the impact of new urbanization on economic growth shows a trend of reverse U-shaped change safters rising and then falling.<br>Subsequently, this paper makes a systematic analysis of the four mechanisms of the new urbanization affecting economic growth, which is also the main innovation of this paper.

On this basis, this paper analyzes the impact of new urbanization on economic growth and its specific mechanism from both theoretical and empirical aspects. The results of theoretical analysis show that the new urbanization can promote the overall economic growth through four mechanisms: consumption change, industrial structure upgrading, urban-rural income gap narrowing and public service supply increasing. However, there are significant differences in its specific path of action. The increase of consumption will directly promote economic growth, and the influence of industrial structure optimization, urban-rural income gap reduction and public service supply increase on economic growth may be nonlinear. But no matter which mechanism, the new urbanization can promote the economic growth in theory. The results of further time series model and panel data model verify the theoretical proposition. On the one hand, the relationship between new urbanization and economic growth is Granger cause, and the impact of new urbanization on economic growth is greater than that of economic growth on new urbanization. The new urbanization that lags behind for one period and four periods can significantly promote growth, while the impact of economic growth that lags behind for the latter period on new urbanization is not significant; on the other hand, add correlation After the control variables, the panel data shows that the new urbanization is indeed an important cause of economic growth, and this positive role has significant temporal and spatial differences. Specifically, the new urbanization plays the most important role in promoting economic growth in the eastern region, followed by the central region, and the western region. At the same time, with the passage of time, the impact of new urbanization on economic growth shows an inverted U-shaped trend of first rising and then falling.<br>Then, this paper systematically analyzes the four mechanisms of new urbanization affecting economic growth, which is also the main innovation of this paper.<br>
