摘要
中国的经济政策,特别是房地产政策存在极大的不确定性,体现在政策本身的种类、出台的时间、频率和力度,以及政策产生的影响等方面。目前针对中国经济政策不确定性的研究极为有限,且缺少着眼于房地产市场的研究。本文使用文本分析方法,基于《人民日报》《环球时报》和《北京青年报》等12份中国内地最具影响力报纸中的1314089篇文章,构建了2000年1月至2018年3月的月度中国房地产政策不确定性指数,同时对所构建指数的稳健性和准确性进行了检验。进一步,文章通过对指数与重要房地产政策发布时间和发布频率关系的解读,展示了构建指数的现实意义以及实践价值。本文首次针对中国房地产市场政策构建了不确定性指标,不仅有助于从不确定性的角度把握中国房地产市场的特点,同时也为文本分析方法在宏观经济以及房地产市场领域的应用做出了贡献。
