Regional inequality in the process of economic growth has recently been a popular topic. This paper creatively proposes contribution decomposition methods to divide various regions' contributions into economic contribution and population contribution. The methods consider not only economic growth but also population change, which may be more effective than the traditional method that uses the per capita GDP (gross domestic product) as its single measurement indicator. Moreover, the objective is to take a step forward and reveal the spatio‐temporal evolution characteristics of regional disparities by integrating barycentre model and economic development equilibrium model. Lastly, the applicability of the research method proposed in this paper is verified by a case study of Jiangsu province, China; the results show a new regional economic pattern in Jiangsu province.

In this paper, we develop an endogenous growth and international trade model with two countries in which equilibrium wages in the two countries are different between two countries. First, when trade costs are high, the share of manufacturing firms in the large country increases with a decline in trade costs because of market size. However, the share of firms then decreases with a decline in trade costs when trade costs are low because of wage differences. Finally, all firms agglomerate in the small country, since production costs in the small country are low. In this process, the innovation sector shifts its location from the large-market and high-wage country to the small-market and low-wage country. [ABSTRACT FROM AUTHOR]

This critical review focuses on the development of spatial competition models à la Hotelling in which the location choice of firms plays a major role. We start by quantifying the research in this field by using bibliometric tools. Thereafter, this study identifies the main research paths within spatial competition modelling. Specifically, the type of strategy (Bertrand vs. Cournot competition), the assumptions that are made in respect to the market (linear vs. circular), production costs, transportation costs, the number of firms and the type of information (complete vs. incomplete) and their effects on the location equilibria are also discussed.
