Economic research on industry location and agglomeration has focused nearly exclusively on manufacturing. This paper shows that services are prominent among the most agglomerated industries, especially at the county level. Because traditional measures of knowledge spillovers, natural resource inputs, and labor pooling explain little of agglomeration in services industries, this paper takes an a...

We study the packing fraction of clusters in free-falling streams spherical and irregularly shaped particles using flash X-ray radiography. The estimated is low enough to correspond coordination numbers less than 6. Such numerical simulations aggregates that collide grow without bouncing. Moreover, irregular evolved faster formed larger sizes with lower fraction. This result on granular suggest...

Agglomeration processes in non-interacting particle systems can be understood from a thermodynamic point of view. If the enthalpy of agglomeration is negligible, the distribution of agglomeration states adopts the state of highest entropy. Herein, we provide the exact analytical solution to the mole fractions of agglomerates comprising i monomers, xi =2-i .

Tax competition for a mobile factor is different in ‘new economic geography settings’ compared to standard tax competition models. The agglomeration rent which accrues to the mobile factor in the core region can be taxed. Moreover, a tax differential between the core and the periphery can be maintained. The present paper reexamines this issue in a setting which, in addition to the core-peripher...

To obtain information on formation mechanisms of dust particles of nm in size in fusion devices, in-situ collection of dust particles produced due to interaction between graphite target as plasma facing materials and the plasmas was carried out in a helicon discharge chamber and in Large Helical Device (LHD). Dust particles produced in the helicon discharges are made of carbon and can be classi...

Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from gold-coated mono-disperse spherical melamine-formaldehyde monomers in a radiofrequency (rf) argon discharge plasma. The behavior of observed dust aggregates is analyzed both ...

Industrial agglomeration has gradually become an economic focus in recent years. Scholars has done a lot of research about the formation mechanism of industry agglomeration and its influencing factors, but the spatial correlation of variables has still been neglected. Firstly this paper gives a brief introduction about Geoda software and Matlab neural network toolbox, then use spatial statistic...

How do foreign trade and foreign direct investment affect regional inequality? Foreign trade and investment may affect internal economic geography, and the resulting industry agglomeration may contribute to regional inequality. This paper provides empirical evidence supporting this linkage. The results indicate that the increasing regional inequality in China has been accompanied by an increase...

This paper aims to correct standard measures of agglomeration economies to account for air pollution generated by commuting. This paper examines the impact of nitrogen oxide (NOX) a pollutant mainly released by transportation on worker productivity. Literature on agglomeration economies highlights the positive role of employment density on productivity, without accounting for the environmental ...
