Marketisation as a channel of international technology diffusion and green total factor productivity: research on the spillover effect from China's first-tier cities

Latecomer technology imitation and learning is an important driving force to enhance their competitiveness and total factor productivity (TFP). This paper constructs green TFP (GTFP) based on the SBM-Global-Luenberger index, using Chinese provincial panel data from 2003 to 2017. The marginal effects of foreign direct investment (FDI), outward foreign direct investment (OFDI), import and export, and intangible and total international technology spillovers (ITS) on GTFP were assessed. These effects were analysed under the influence of absorption capabilities such as research and development intensity, economic and financial, and openness. A spatial diffusion model based on three diffusion sources in China's first-tier cities, Beijing, Shanghai, and Guangzhou, was constructed to describe the heterogeneous impacts of ITS on GTFP under the marketisation of diffusion sources. We found: (1) ITS based on exports and OFDI promote economic, imports and FDI are relatively small, independent technological innovation is the dominant source of economic growth. (2) Considering spatial diffusion, the contribution of Beijing's ITS is relatively weak, and Shanghai's contribution is stronger. Coastal areas have the largest marginal effect of ITS on GTFP, and ITS do not attenuate as geographic distances increase. (3) The market has a multiplier effect, modifying the relationship between ITS and GTFP.

Automated summary

The study found that international technology spillovers have a significant impact on green total factor productivity, especially through exports and outward foreign direct investment. Taking spatial diffusion into account, Beijing's contribution to technology spillovers is relatively weak, while Shanghai's is stronger. Coastal areas have the largest marginal effect of technology spillovers on green total factor productivity.
