能源和环境瓶颈是制约我国经济持续快速健康发展的重要问题，也是中国政府面对的严峻挑战。目前中国已成为世界上最大的能源消费国和温室气体二氧化碳排放国，以雾霾天气为代表的空气污染近年来也有明显的加剧趋势。就中国现阶段的发展情况而言，空气污染与能源消费和以增长为导向的政府支出模式有密切关系，且三者都存在着较强的空间相关性。然而目前将政府支出、能源消费和空气污染三者整合起来的研究还很少。本项目拟在充分考虑空间相关性的基础上，利用中国省级和更精细的县市级数据，将政府支出、能源消费和空气污染纳入综合性的研究框架，从理论和实证两方面深入考察政府支出行为对能源消费和空气污染的影响。本项目的研究可以帮助判断中国未来能源消费和空气污染的变化趋势，并为我国如何通过进一步转变政府职能，优化政府支出的总量和结构，以加快经济结构转型和优化、破解能源和环境瓶颈、实现可持续发展提供研究基础和决策支持。

Energy and environment bottleneck is one of the most important issues that may affect China’s sustainable and healthy economic development. It is also a great challenge faced by Chinese government. Currently China has become the largest energy consumer and carbon dioxide emitter in the world. China’s air pollution, represented by fog and haze that appeared frequently in recent years, has become increasingly serious. In the context of China, air pollution is closed related with energy consumption and growth-oriented government expenditure, and the spatial dependence of air pollution, energy consumption and government expenditure is quite significant. However, so far there have been very few researches on the relationship of the three items. In this program, we will for the first time incorporate government spending, energy consumption and air pollution into the same research framework. After taking into account of spatial dependence, the impact of government spending on energy consumption and air pollution is investigated from both aspects of theory and empirics by utilizing China’s provincial and city and county data. Through this program, the trend of China’s future energy consumption and air pollution could be predicted in a more reasonable way. This research could also serve as solid basis and good references for China’s government to accelerate the transformation of the pattern of economic development and break the energy and environment bottleneck by adjusting and optimizing the scale and structure of government spending.
