Based on panel data of smart elderly care level indicators at the provincial level in China from 2008 to 2023

As of 2023, the smart elderly care policy has established five batches of pilot provincial administrative units. The first batch in 2017 includes Beijing, Tianjin, Shanghai, etc., the second batch in 2018 includes Shanghai, Jiangsu, Zhejiang, etc., and the third batch in 2019. Batch, the fourth batch in 2020 and the fifth batch in 2022. Although there are five batches of pilot projects, the second and third batches of pilot projects have a short time and are less affected by policies, and the fourth and fifth batches are almost consistent with the first batch of pilot cities, so this paper selects the first batch of pilot projects for research. The experimental areas are distributed in the eastern, central and western regions of China, and we use samples from other provincial administrative units in China as control groups. After eliminating the samples with missing values, we selected the panel data of 31 provincial administrative divisions as samples, of which 21 provincial administrative divisions were the experimental groups. Finally, we obtained 496 observations between 2008 and 2023. All data come from China Statistical Yearbook, White Paper on Smart Pension Industry, reports published by provincial government platforms and annual reports of enterprises.
