Poverty and inequality remain outstanding challenges in many global regions. Understanding the underlying social and economic conditions is important in formulating poverty eradication strategies. Using Visible Infrared Imaging Radiometer Suite (VIIRS) Night-Time Light (NTL) images and multidimensional socioeconomic data between 2012 and 2018, this study measured regional poverty and inequality in the Xiamen-Zhangzhou-Quanzhou city cluster in the People’s Republic of China. Principal Component Analysis (PCA) and the Theil index decomposition method were used to establish an Integrated Poverty Index (IPI) and a regional inequality index, respectively. The results indicated that: (1) The poverty index is affected by the geographical location, policies, and resources of a district/county. A significant logarithmic correlation model between VIIRS Average Light Index (ALI) and IPI was established. (2) The Theil index derived from Gross Domestic Product (GDP) indicators showed that overall inequality and between-prefecture inequality declined, while within-prefecture inequality remained unchanged. In terms of the contributions to regional inequality, the contribution of within-prefecture inequality is the largest. The results indicated that Suomi National Polar Partnership/Visible Infrared Imaging Radiometer Suite (NPP/VIIRS) night-time data can help to perform district/county-level poverty assessments at small and medium spatial scales, although the evaluation effect on regional inequality is slightly lower.

Logistics is an indispensable part of today's life, and its development is of great significance for social and economic development. Beijing, as the capital of China, is one of the four first-tier cities. The development characteristics of the logistics market have certain typical characteristics. This article has conducted an in-depth analysis of the status quo of the development of the Beijing logistics market, and the problems existing in the development of the Beijing logistics market. Combined with Beijing logistics market development plan, put forward the scientific planning and construction of Beijing logistics market system as the prerequisite, to the cultivation of professional talents as the center of gravity, relevant policy to develop the logistics industry, the logistics industry standard to ensure the train of thought to develop the logistics market in Beijing.
