Despite the continuous expansion of trade and investment agreements between China and South Korea, little is known about the distribution of benefits and losses stemming from synergy and competition at the regional level. This paper aims to investigate the complementary and competitive interactions among 14 economic regions of the two countries concerning bilateral export scale. Using a Dendrinos-Sonis model based on a zero-sum structure, we analyzed the interregional trade patterns between the two countries from 2002 to 2022. The evidence shows that the growth of Seoul metropolitan area is complementary to the growth of Shanghai metropolitan area in terms of regioinal export share, but not vice versa. Central Area in South Korea exhibits widespread complementarity, while Beijing metropolitan leans towards competition.
Regions and industries are not isolated islands; so, when evaluating productivity growth, regional and sectoral growth paths should not be expected to generate independently. Moreover, accounting for spatial interactions via econometric models has become normal practice; but modelling interindustry dependencies has not. Thus, we expand labour productivity econometric convergence models by introducing interindustry spillovers in addition to spillovers that are spatial in nature. To illustrate our findings, we present an empirical application predicated upon Galicia (extreme northwest Spain), a region posing major challenges to such modelling. Our results point to the relevance of interindustry spillovers in explaining productivity growth. Furthermore, the approach allows us to better interpret covariates that explain the different growth paths across regions and industries, thus enabling more reliable policy recommendations. We find that interindustry dependencies transmit productivity shocks across regions. In addition, our results suggest that spatial and interindustry dependencies should be considered when formulating (sub)regional economic development policies. Finally, our approach corrects possible misspecification problems that arise from data scarcity. This makes it a viable alternative for multiregional econometric tests in which some sectoral detail is needed. It is particularly useful for sets of regions where data needed to populate such models is scarce.
In this paper we investigate the role of EU structural funds in promoting economic growth of Italian provinces (NUTS 3), and whether a more developed local banking sector may expedite the process. We focus on total value added growth for the period 2000–2019, and employ a panel growth regression approach where a measure of funds coming from EU public programs, and spent in a given province, is interacted with a variable measuring local banking development. Our empirical results show that areas receiving structural funds have relatively higher value added growth rates when local banking markets are more developed. This evidence is robust to alternative model specifications, and holds even when we employ spatial panel models so as to account for geographic spillovers between provinces.
