This research quantifies productivity-related agglomeration benefits arising from the concentration of employment in Australia. While agglomeration provides a policy rationale for densifying cities and concentrating employment, it also leads to higher house prices, which reduce entry and ongoing affordability, greater pollution and other wellbeing detriments such as crime, crowding and noise.

The article describes the possible impact of modern technological changes (disruptive technologies, digitalization, and automation) on regional development in Russia based on the patterns of geography of innovations and previous trends. The rates of non-resource growth over the past twenty years have been higher in those regions where inventive activity, intensity of R&D expenditures, share of researchers and employees with higher education were higher, but the same relationship cannot be traced with the intensity of the use of advanced production technologies (automation) and the availability of the Internet. During the declared pandemic in Russia in 2020, patent activity in the vast majority of regions decreased, the processes of production automation slowed down, but digitalization accelerated in terms of internet access and the development of online commerce. The creation of disruptive technologies is still concentrated in large cities and super-regions due to agglomeration effects, knowledge spillovers and concentration of human capital. But the effects of their introduction and distribution can be differentiated. In the leading regions with high proportion of creative professionals and entrepreneurs, development may accelerate, in old industrial regions, automation will increase the risks of temporary unemployment and inequality. For the least developed territories, the lack of digitalization potential and lack of highly qualified personnel may further worsen the situation.

Kinetic hydrate inhibitors (KHI) and anti-agglomerants (AA) rather than thermodynamic hydrate inhibitors (THI) are often used for flow assurance in pipelines. This is because they require much lower dosages than thermodynamic inhibitors. Although the hydrate-phase equilibria are not affected, KHI and AA prevent the formed hydrate crystals from growing to a bulky state causing pipeline blockage. However, these KHIs might have huge environmental impact due to leakages from the pipelines. In this study, two biodegradable AA candidates from natural sources (that is, lecithin and lanolin) are proposed and their performances are evaluated by comparing them with and without a conventional AA (Span 80, sorbitan monooleate). At 30% and 50% water cut, the addition of AA materials was found to enhance the flow characteristics substantially in pipelines and hardly affected the maximum value of the rotational torque, respectively. Considering the cost-effective and environmental advantages of the suggested AA candidates over a conventional AA such as Span 80, the materials are thought to have potential viability for practical operation of oil and gas pipelines. However, additional investigations will be done to clarify the optimum amounts and the action mechanisms of the suggested AAs.

Industry cluster’s agglomeration effects facilitate higher productivity for enterprises located in the industry cluster. This paper examines the agglomeration effects of industry cluster on firm’s innovation performance through studying the network embeddedness of the biopharmaceutical companies using cross-sectional data from 2011 to 2015. Measuring the technological cooperation network with text analysis of the interfirm agreement among core enterprises, we found that betweenness centrality and clustering coefficient have statistically significant and positive effects on enterprise’s ability for technological innovation, while the influence from the constraint of structural holes is negative. Our results suggest that government should allow the leading enterprises to establish professional technology cooperation platforms and provide additional support to promote cooperation among firms.
