本文建立一个一般均衡模型刻画了中国地方政府出让土地、投资基础设施和主导经济增长的行为。模型发现，在政治集权和经济分权的体制下，中国地方政府官员为了追逐政治晋升收益与私人经济收益．会利用土地处置权，在垄断的土地市场上策略性地设定土地出让价格与土地出让规模，进而利用土地出让收入与相关税收收入，投资公共基础设施以推动经济增长与获取财政收入。地方政府官员的晋升动机越强、向中央发送能力信号的效率越高、提供基础设施的效率越高、受到的监管越严格、地方政府税收留存比例越高、土地原始征用价格越低，则地方政府官员倾向于出让更多的土地、提供更多的公共基础设施．实现更高的经济产出。各种经济与政治因素在影响最终产出水平的同时，也影响了地方政府税收收入、地方政府土地出让收入、居民收入以及地方政府官员私人经济收入．改变了整个经济的收入分配格局。
