Research of RaD Marginal Productivity Driving Economic Convergence

Abstract

Abstract-The convergence mechanisms of regional economics have become one of hot issues. In this paper we propose the concept of R&D marginal productivity to study economic convergence, which is defined as the economic marginal product relative to R&D capital stock. We find: whether from the angle of σ convergence or from dynamic evolution of That confirms that R&D marginal productivity drives the convergence of GDP per labor. We also find there are some other convergence mechanisms to play roles in China.

The Impact of Lagged R&D Expenses on Firm Performance: Empirical Evidence from the BSE Healthcare Index

“…From the theory in Economics, we know that shape of a curve depends on the marginal utility of the R&D expenditure (Fredriksson & Wikberg, 2015). Few authors have however used the term marginal product of R&D expenditure (Peters et al, 2013;Ren & Wang, 2013). The shape of the curve depends on the nature of marginal utility.…”

Empirical Study of Regional Innovation Capability and Economic Convergence in China

“…Studies by Wang and Zhaopan (2002) show that there is club convergence in the country's three main regions: eastern, central and western China. Studies by Lin and Mingxing (2003) show that there was conditional convergence in China's regional economy over the period 1981-99, while research by Ren et al (2014) shows that the marginal productivity of research and development (R&D) has significant driving effect on regional economic convergence in China.…”
