On the driving forces of green total factor productivity growth in China: evidence from biased technological progress analysis

Abstract

The traditional model of factor-driven economic growth can no longer be maintained due to an increasing demand to save energy and reduce emissions and a rapid rise in the cost of related factors. The concept of green total factor productivity (GTFP) has emerged as an essential component of high-quality economic growth; consequently, how to boost GTFP through the development of technical advancement has become an important question in recent years. An improved CES production function of labor, capital, and energy is created using the theoretical framework for biased technological growth as its foundation. Subsequently, the mechanisms resulting from the synergy of factor structure, factor efficiency and biased technological progress (BTP) on GTFP are theoretically deduced and empirically analyzed. The conclusion shows that the types of technical advancement are mainly net labor-enhancing and net energy-enhancing technical advancement in China from 2001 to 2017. Due to the biased effect of technical advancement, the relative comparison of the three elements is determined predominantly by excessive capital investment and less by labor and energy. Factor-enhancing technical advancement led to the growth of GTFP, while the synergistic effect of BTP, factor structure and factor efficiency hindered the growth of GTFP.
