Financial Efficiency Differentiation Based on Data Quantitative Analysis under Big Data Technology
Published in Noura Metawa, M. Kabir Hassan, Saad Metawa, Artificial Intelligence and Big Data for Financial Risk Management, 2023
The common methods to compare regional differences are the Gini coefficient, Theil index, coefficient of variation, and so on. In this chapter, the Theil index is used to measure the difference between pure technical efficiency and scale efficiency, and the Theil index is decomposed into intra-regional and inter-regional differences, the algorithm is as follows: Tw=∑K=1mfKUKUT(ZK),Tb=∑K=1mfKUKUlnUKU
Equity impacts of cycling: examining the spatial-social distribution of bicycle-related benefits
Published in International Journal of Sustainable Transportation, 2023
A recent study readjusted the formulation of the Theil Index by replacing income with a composite bicycle accessibility indicator, assessing the contribution of individual characteristics (e.g., citizenship status) to the total spatial inequality (Hamidi et al., 2019). Initially, the Theil index is a decomposable technique used to measure income inequality, revealing an entropic distance or how far a population is from the egalitarian line. The Atkinson index also has an entropic structure and is sensitive to differences in the distribution scale, especially at the bottom, therefore being valuable to determine which part of the distribution contributes most to the observed inequality (Zuo et al., 2020).

Determining the regional disparity of CP in China’s transportation industry not only develops the understanding of emissions reductions by the transportation industry, but also provides a new regional-level reference. The Gini coefficient and Theil index are two indices commonly used to measure inequality. Through the corresponding decomposition method, the factors of the degree of inequality and their contributions can be analyzed. In order to measure the inequality in CP for China’s transportation industry and analyze the influencing factors of CP from multiple perspectives, we employed the Gini coefficient decomposition approach and Theil index decomposition approach for the inequality analysis.
Study of the accessibility inequalities of cordon-based pricing strategies using a multimodal Theil index

The paper presents a method to analyse the distribution of multimodal accessibility (which should be the concern of urban and regional planners instead of other mobility-related factors (Straatemeier 2007)) deriving from the application of a congestion price scheme on an urban network, across different social groups and geographical districts of the city. We suggest the use of the Theil index (Theil 1967), an indicator implemented in other fields to assess the level of inequalities existing in a given context. We propose to use it for planning purposes, to evaluate the implications in terms of inequalities of different pricing scheme designs.
