Government Health Expenditure, Economic Growth, and Regional Development Differences-Analysis Based on a Non-parametric Additive Model.

Government health expenditure plays an important role in guaranteeing people's livelihood and in improving the quality of human capital, and it also plays an important role in affecting economic development. In order to characterize the specific trend of government health spending affecting economic growth, and analyze the impact difference in different regions, this paper uses a non-parametric additive model to analyze the impact of government health expenditure on economic development and regional development differences based on three aspects: linear, non-linear and comprehensive effects. From the perspective of linear effects, the results show that the proportion of government health expenditure to GDP nationwide and in the western regions has a positive impact on economic development, while the impact in the eastern and central regions is negative. From the perspective of non-linear effects, in the national and in the eastern, central and western regions, the proportion of government health expenditure to GDP has a significant non-linear impact on economic development. From the perspective of comprehensive effects, the proportion of government health expenditure to GDP has a significant non-linear positive effect on economic development nationwide and in all regions. In addition, the proportion of fixed assets investment to GDP, the proportion of exports to GDP, and the proportion of residents' income to GDP promote non-linear effects to different extents of non-linear promotion, but there are slight differences in different regions. Based on estimation results, the paper recommends that the government further expands the proportion of government health expenditure in GDP, promotes investment in fixed assets, stimulates exports in the eastern region, and continues to implement the western support policy.
