长假对促进消费、拉动经济增长起到了很大的作用 ,但是要具体研究长假消费对国民经济的影响 ,必须以年度和全国数据为基础 ,考虑长假所引起的消费的时间分布和地域分布的变化。把长假作为虚拟变量引入二元回归模型进行具体分析 ,指出假日经济在一定程度上调整了我国的消费结构 ,其作用主要是改变了居民的消费偏好。 Long holidays have played a significant role in promoting consumption and stimulating economic growth. However, to study the impact of holiday consumption on the national economy, we must consider the time-consuming distribution of consumption and the change of geographical distribution based on the annual and national data . As a dummy variable, the paper introduces the long-term variable into the dual regression model, and points out that the holiday economy adjusts the consumption structure of our country to a certain extent. The main function of the holiday economy is to change the residents’ consumption preference.
