This work tests the validity of Gibrat’s law on the growth of cities, from the US, Spain and Italy, for the entire 20th century. First, panel data unit root tests tend to confirm the validity of Gibrat’s law in the upper-tail distribution. Secondly

This article examines the Piedmont megapolitan political ecology and urban metabolism in Southern Appalachia. First, it considers the central role urban metabolic connections play in the region's pressing social and environmental crises. Second
, it illuminates these human and nonhuman urban metabolisms across the Piedmont megapolitan region using data from the Coweeta Long-Term Eco-logical Research (LTER) program, especially highlighting a growing “ring of asphalt” that epito-mizes several developing
changes to patterns of metabolism. The conclusion suggests that changing urban metabolisms indicated by Coweeta LTER data, ranging from flows of people to flows of wa-ter, pose a complicated problem for regional governance and vitality in the future.

This article examines almost 200 years of regional change in the United States and finds that few, if any, growth relationships remain constant. Human capital spillovers occur at the city level because skilled workers produce more product varieties
and thereby increase labour demand. It is found that skills are associated with growth in productivity or entrepreneurship, not with growth in quality of life, at least outside of the West. Evidence is also presented that skills have had a disproportionately

Using data for 2002–2010 from 358 Metropolitan Statistical Areas (MSA), the A estimate Okun’s law which accounts for national shocks and spatial spillovers in urban areas. Our scale of measurement is changed to the state level, allowing us

The paper summarizes the mineral resource exploitation development of Xinjiang especially over the last 50 years, and investigates energy industries and their driving forces, directions, and economic impact on the oasis urban system evolution
growth is promoted by the contributions of the increasing mineral resource industry which promotes economic development. The statistical results provide strong evidence to support the argument that mineral resource exploitation has promoted the growth

This study examines the long-term changes (1971–2001) in the socio-economic structure of Rome, undergoing moderately polycentric development. The socio-economic disparities observed along the urban-rural gradient in 1971 decreased only moderately
in 2001. Results indicate that exurban development has impacted only partly Rome's urban form which remained mainly compact and dense with persisting socio-economic gaps between urban and suburban areas. The paper discusses the partial failure of Rome's
master plan to promote a really polycentric development and a new, more sustainable, urban form.

unfolded that the expansion of economic scale is the main driver of the rapid growth of carbon footprint. Thirdly, developing low-carbon economies and low-carbon industries, as well as advocating low-carbon city construction and improving carbon efficiency
would be the primary approaches to inhibit the rapid growth of carbon footprint. Moderately controlling the economic scale and population size would also be required to alleviate carbon footprint.
