“…The spatial related problems of regional economy cannot be ignored. Not only does it have an impact on regional elements, but because of the transportability of inter-city resource elements, resource exchange between regions will also be closely related to form an organic whole [13]. In addition to the transfer and exchange of goods and labor resources between regions through convection, total factor productivity, as one of the economic contributions, also has spatial spillover [8,14].…”

Based on the county panel data of 181 districts and counties in Sichuan province from 2008 to 2018, the spatial spillover effect of county-level total factor productivity was studied by using Spatial Dubin Model, and the heterogeneity of Chengdu-Chongqing urban agglomeration and non-urban agglomeration was analyzed. Finally, the robustness test was carried out by using economic distance spatial weight matrix. The study has demonstrated that TFP at the county level in Sichuan province has spatial autocorrelation, and the level of economic development, the industrial structure, the industrial agglomeration, the human capital and the government intervention have different impacts and spatial spillover effects on TFP at the county level in Sichuan province, but there are differences within and outside the urban agglomeration.

“…As noted, the basic model relies on an analogy to Newton's law of the gravitational force between two masses (e.g., population size, number of jobs, activities, or something else) separated by distance. Due to their simplicity and usefulness, these models have been the primary standard in spatial and transport planning in recent decades [58,77,79,[91][92][93][94][95][96][97][98]. Over the years, especially with state-of-the-art Geographic Information (GI) developments, accessibility studies have taken different forms according to new abilities opened.…”

Spatial accessibility is fundamentally related to the functional, economic and social performances of cities and geographical systems and, therefore, constitutes an essential aspect for spatial planning. Despite the significant progress made in accessibility research, little attention is given to the central role of accessibility in space organization and structuration. This study aimed to fill this gap. Based on an intensive literature review, our work shows the critical role of accessibility in space organization at different scales and sizes, starting from the basic concept of accessibility and its foundations in the classical locational theories and further to the methods and theories at the forefront of research. These processes also point to a unique contribution of multiscale accessibility in space structuration. Accordingly, we offer a conceptual framework to describe the multiscale process of space structuration with respect to local-urban, regional and national scales. We believe this framework may help in studying space and, more importantly, in understanding space. We hope this perspective forms an additional tier at the conceptual and methodological levels concerning accessibility and spatial organization and will encourage empirical studies in light of the suggested view.

“…While the DB1B database is a common data source in air transportation research, we believe that its fine geographic and thematic detail conceals a greater wealth of information that could provide unparalleled insights into the formation of airline market structures over time and across space. Ullman's (1957) seminal study of US commodity flows and the Chicago Area Transportation Study (1959) of personal travel introduced the exploratory analysis of SI data. These early studies represent movement by `desire lines' or rectangular flow bands with width proportional to flow magnitudes.…”

Given that many spatial interaction (SI) systems are often constituted in large databases with high thematic dimensionality, data complexity reduction tasks are essential. The opportunity exists for researchers to examine the formation of different types of SIs as well as their interdependencies by exploring the patterns embedded in the data. To circumvent the limitations of existing methods of flow data compression and visual exploration, we propose an integrated computational and visual approach, known as VISIDAMIN, for handling both SI data projection and SI data quantization at once. The computational method of self-organizing maps serves as the data mining engine in this process. Using a large domestic air travel dataset as a case study, we examine how the characteristics of the air transport system interact with the SI system to create relationships and structures within the US domestic airline market.
