I construct a theoretical and computational model of municipal fragmentation and Tiebout competition and show that factors such as income heterogeneity, political institutions and the discretionary power of municipalities to tax can substantially affect both where individuals choose to live and how cities form. Conclusions are drawn about the types of cities that form when secession is an optio...

Sixty five patients (20 children and 45 adults of both sexes) having hepatomegaly were subjected to serum copper, hepatic copper and hepatic cuproprotein analysis from October 1982 through September 1983. Higher levels of serum copper were encountered in 17/20 children suffering from Indian Childhood Cirrhosis (ICC), values ranging from 151 ug/dl to 350 ug/dl. Hypercupremia was also detected in...

Purpose—The unbalanced layout of digital economy agglomeration has a significant impact on regional high-quality development. This study aims to explore the green total factor productivity (GTFP) disparity from two aspects, including theoretical mechanism and empirical effect. Design/methodology/approach—Based data 285 cities above prefecture level in China 2003 2018, super-efficiency undesired...

Improving urban ecological efficiency is an integral part of protection and high-quality development the Yellow River Basin. We used super-efficiency slacks-based model with unexpected output to measure 62 prefecture-level cities in Basin from 2005 2018. Its spatial distribution characteristics convergence are discussed. The influencing factors spillovers assessed through Dubin model. results s...
