隋代陕西人口研究

An Examination of Shaanxi's Population in the Sui Dynasty

以往学者对隋代陕西人口数量的估算普遍偏低。本文利用"户口平均密度法"，对《隋书·地理志》所载北地、弘化、汉川等兼跨今陕西与邻省之地的各郡户数进行了分割。经估算，大业五年(609年)今陕西境内在籍人口数为378.8万口；如果加上未列入政府版籍的各种人口，当时陕西境内实际人口数约为423.8万人。隋末陕西人口峰值约为435万人左右。

Almost all the previous scholars made an underestimate of Shaanxi's population in the Sui Dynasty. By means of 'the densifying of average households', the present paper divides the numbers of households in such counties as Beidi, Honghua, Hanchuan, etc., which overlapped Shaanxi and adjacent provinces, recorded in Geographical Volume of the Book of Sui. Through the above estimate, the registered population within the bounds of what is now called Shaanxi was 3.788 million heads in the 5th year of the Reign Title of Daye(609). With the diverse unregistered population beyond the governmental registration, the then population in Shaanxi was appoximately 4.238 million heads. Therefore, the peak value of Shaanxi's population was about 4.35 million in the late Sui Dynasty.
