“…The population in China is unevenly distributed, with approximately 94% of the population concentrated in only 43% of the land area. This concentration of population in the southeast region has resulted in high population density, while the northwest region has a lower population density [ 37 ]. The socioeconomic status of the eastern coastal region is higher than the central and western regions.…”

Introduction The emergence of electronic cigarettes (e-cigarettes) poses a new challenge to tobacco control efforts. With their increasing popularity, particularly among youth, public concerns have been raised in Mainland China. Further investigation is necessary to fully understand the safety and potential adverse effects of e-cigarettes. Methods The Baidu search index (BSI) was employed using e-cigarette related terms from January 1, 2011, to April 4, 2022. The search volume for each term was recorded and analyzed for the search trend module, geodemographic module, search-demand module, regional preferences, demographic preferences, and user demand. Results According to our analysis, the total BSI for the 18 e-cigarette related search keywords was 39,027,819. The average annual percentage change of BSI indicated an upward trend for each of these categories, including health issues ( p < 0.05), definition ( p < 0.05), product and promotions ( p < 0.05), and policy and regulations. Of all inquiries, 59.38% originated from females and 40.62% from males. The total valid BSI for e-cigarette related words was 165,076,588, and 11.59% of all search inquiries were from individuals aged 19 years and younger. Our analysis also revealed that the public's primary concerns regarding e-cigarettes were related to their quality and potential health issues. Conclusions E-cigarettes enjoy great popularity nationwide, but product quality and safety are major public concerns. Regulation of e-cigarettes for their standard production, quality control, advertisement, and target customers should be implemented promptly, and the public needs to have a clear perception of e-cigarettes, especially adolescents. E-cigarette related health damages or consequences require further investigation, and advertisements and promotions for e-cigarettes should be strictly controlled by the government.

“…While geopolitical tensions with the Soviet Union, and later Russia became less acute around this time, the Chinese state also did not want to depopulate the border areas and tip the balance of power in Russia's favor (Huang, Lang and Liu, 2020) Therefore, while other sectors of the economy were liberalized and grew, reforms for state farms happened much more slowly, and property rights, labor flexibility/mobility, and ability to engage in non-agricultural economic activities were relatively constrained under the state farms.…”

Why do post-colonial states engage in population resettlement in their frontier territories? In this paper, we shift away from the motivations for resettlement by advancing a cost-centric theory for resettlement. We contend that states may use the resettlement policy because they inherit the infrastructural capital to do so from settlers of former colonial powers seeking to consolidate their frontiers. We test the observable implications of the theory using a unique geo-coded archival dataset and in Manchuria, a northeastern border region of China. We find that areas that received more Japanese settlers during the colonial period (1931-45) are associated with greater proximity to Chinese settlers in the post-colonial era (1945-). We also show that, contrary to existing findings on settlement and growth, Japanese settlements led to slower economic development. By focusing on cost our paper expands our understanding of resettlement policies and uncovers an alternative relationship between settlement and economic development.

“…However, some densely populated areas, such as Dandong, have stagnated. Huang et al used census data to analyze the population distribution of 131 border counties in China from 1982 to 2010 [56]. However, the demographic analysis based on administrative units has coarsened the spatial differences in population density.…”

Monitoring human activities in border areas is challenging due to the complex geographical environment and diverse people. China has the longest terrestrial boundary and the highest number of neighboring countries in the world. In this study, a human activity intensity index (HAI) was proposed based on land cover, population density, and satellite-based nighttime light for a long-term macroscopic study. The HAI was calculated at 1 km resolution within the 50 km buffer zone of China’s land boundary on each side in 1992, 2000, 2010, and 2020, respectively. Results show that human activity is low in about 90% of the study area. Overall, the HAI on the Chinese side is higher than that on the neighboring side, and the intensity of land use on the Chinese side has increased significantly from 1992 to 2020. Among China’s neighbors, India has the highest HAI with the fastest growth. With the changes in the HAI between China and its neighboring countries, four regional evolution patterns are found in the study area: Sino-Russian HAI decline; Sino-Kazakhstan HAI unilateral growth; Indian HAI continuous growth; China and Indochina HAI synchronized growth. Hotspot analysis reveals three spatial evolution patterns, which are unilateral expansion, bilateral expansion, and cross-border fusion. Both the “border effect” and “agglomeration effect” exist in border areas. The HAI changes in border areas not only impact the eco-environment but also affect geopolitics and geoeconomics. The HAI can be used as an instrument for decision-making and cooperation between China and neighboring countries in such areas as ecological protection, border security, and border trade.
