Urbanization, Economic and N Emissions in China -An Empirical Study Based on Panel Data and Granger Causality
[Objective] Studying the relationships among issues of urbanization
economic growth and nitrogen emission in 31 provinces of China from 2001 to 2015
and to provide theoretical support for the sustainable development of urban environment.[Methods] Co-integration test
panel unit root test
and Granger statistical causality test were used jointly.[Results] (1) The urbanization of China
particularly of the western
central and eastern areas
contributed to the economy development. The urbanization and the successive economy development led to the increase of nitrogen emission. The urbanization in western area contributed more proportional than it did in central and eastern areas. In contrary
the economy development in eastern areas had lager contribution. (2) The panel causality results revealed that there were a long-run bidirectional causal relationship among urbanization
economy development and nitrogen emission. Two unidirectional links were found
one was from urbanization to economy development
another one was from urbanization and economy development to nitrogen emission. For different region
the causal relationship exhibited different direction traits. In eastern and central areas
the relationship between urbanization and economy development was long-run bidirectional. While the link from urbanization to N emission
and the link from economy development to N emission were both short-run and unidirectional.[Conclusion] The government should reduce the amount of nitrogen by controlling the speed of economic growth and urbanization
and by adjusting the industrial structure and increasing the utilization rate of energy.
