公司热辐射数据

公司热辐射数据库基于卫星图像的分辨率和更新频率，分为高清低频和低清高频数据库。公司热辐射-高清低频数据库利用空间分辨率为 30m，重返周期为 16 天（2021 年 11 月后变更为 8 天）的遥感卫星图像反演出热辐射；公司热辐射-低清高频数据库利用空间分辨率约为 1km 的遥感卫星图像反演出每天日间和夜间的热辐射。对公司矢量数据进行切割，得到了 3361 家制造业上市公司及其子公司在 2013 年至今的热辐射数据，利用热辐射强弱的变化反应公司生产经营活动强度。The corporate thermal radiation database is categorized into two types based on the spatial resolution and update frequency of satellite imagery: high-spatial-resolution low-temporal-frequency and low-spatial-resolution high-temporal-frequency databases. The high-spatial-resolution low-temporal-frequency thermal radiation database retrieves thermal radiation data from remote sensing satellite imagery with a spatial resolution of 30 meters and a temporal revisit cycle of 16 days, which was adjusted to 8 days after November 2021. The low-spatial-resolution high-temporal-frequency thermal radiation database retrieves daily daytime and nighttime thermal radiation data using remote sensing satellite imagery with a spatial resolution of approximately 1 km. By clipping the vector data of the target companies, thermal radiation data for 3361 manufacturing listed companies and their subsidiaries from 2013 to the present was obtained, where changes in thermal radiation intensity are used to reflect the intensity of the companies' production and business activities.
