E-commerce and online shopping have become more convenient due to the rapid growth of the internet logistic industry in many developed countries and are particularly popular and suitable in China. The method is primarily based on logistic points like attended collection and delivery points (ACDPs), an emerging industry for economic development. This article includes descriptive statistics, and spatial analysis to analyse the location distribution, and influencing factors of ACDPs in Nanjing City using point of interest data (POI) of Cainiao stations and China Post stations. The results show that the spatial distribution of ACDPs in Nanjing is asymmetrical, displaying a trend to the northwest direction and a difference in the trend between the S-W and N-E axes. Their layout creates four main core areas and the number of sites decreases with distance from the core. Most of the ACDPs are in urban areas and on residential and industrial land. This study provides insightful ideas for decision-makers and planners to help formulate policies that can lead to more sustainable logistic enterprises development and for the companies that want to establish successful CDP networks in big cities.

Historically, informal adoption has been a prevalent Chinese social phenomenon that has altered typical family structures and the lives of children. Due to ambiguous definitions and the scarcity of data on informal adoption, the patterns and processes of informal adoption are not well understood. Therefore, in this study, data from commonwealth websites were used to explore the temporal and spatial patterns and network evolution of informal adoption from 1924 to 2018. The results indicate that severe famine and birth control campaigns increased the number of informal adoptions. Son preference was highlighted during the strict implementation of the one-child policy. From a spatial perspective, the data are distributed in provinces and zones with higher population densities. Major cities also play a key role in information transfer. We expect the findings to provide basic knowledge on informal adoption in China and serve as a reference for the protection of children's rights.

E-commerce and online shopping have become more convenient due to the rapid growth of the internet logistic industry in many developed countries and is particularly popular and suitable in China. The method is primarily based on logistic points like attended collection and delivery points (ACDPs), an emerging industry for economic development. This article includes text analysis, descriptive statistics, and spatial analysis to analyze the operation types, service objects, location distribution, and influencing factors of ACDPs in Nanjing City using point of interest data (POI) of Cainiao stations and China Post stations. The results are as follows: 1) ACDPs have a mainly independent mode of operation, but some are reliant on supermarkets, department stores and individual shops. 2) The main service targets of ACDPs are communities, schools and townships followed by businesses, enterprises, and office buildings. 3) The spatial distribution of ACDPs in Nanjing is asymmetrical, displaying a trend to the northwest direction and a difference in the trend between the N-S and E-W axes. Their layout creates four main core areas and the number of sites decreases with distance from the core. 4) Most of the ACDPs are in urban areas and on residential and industrial land. This study provides insightful ideas for decision makers and planners to help formulate policies that can lead to more sustainable logistic enterprises development and for the companies that want to establish successful CDP networks in big cities.
