Recomputation of Public Capital Based on PIM and the Effect on China Regional Economic Growth

Abstract

This paper first reestimates the public capital stock of each China province from 1994 to 2019 by improving the computing method of the components of the perpetual inventory method (PIM). Then, it brings the public investment and public capital into the extended Cobb-Douglas production function and explores the mechanism of public investment affecting economic growth from the regional perspective. Furthermore, through the analysis of the Local Government Financing Vehicles (LGFVs) as the major investor of local public investment during the last two decades, This paper confirms the importance of complementary factors such as institutional innovation and effective management of the public infrastructure in making public investment an “effective catalyst for growth” (Kessides, 1993).
