This study constructs a comprehensive energy price index and applies the Morlet continuous wavelet transform to investigate the relationship between energy prices and energy industry stock markets. It also tests the multi-scale linear and nonlinear causality using multi-resolution decomposition. The empirical findings indicate that: (1) energy pric...

Literatures focus on whether formal environmental regulatory policies can effectively stimulate green total factor productivity (GTFP), but generally ignore the role of informal institutions such as public environmental appeals. This paper uses inter-provincial panel data and Non-Radial Slacks-Based Measure (SBM) model to measure GTFP. With the Bai...

Using the data of 281 representative cities of China, this study designs industrial intellectualization indicators from three dimensions of regional information intelligence, production intelligence, and intelligent innovation. Then the mixed distance EBM-DEA model that includes undesired outputs is employed to calculate the carbon total factor pro...

Environmental regulation and green technology progress are important means to solve the negative externalities of the environmental pollution. Despite the widespread concern on the impact of environmental regulation on green technology progress, the existing literatures focus on the relationship between them mainly in the local parts of the same re...

Using the monthly Producer Price Index (PPI) of 37 different industries in China from 2007 to 2017, this study established a Markov regime -switching model to analyze the regime differences and industry heterogeneity of the transmission of volatility from energy price to PPI. The results showed that volatility in energy prices within a given regime...

This study pioneers investigating the environmental Kuznets curve (EKC) hypothesis and its possible regional differential characteristics in China. Based on 2003–2017 years of provincial panel data, this research employs panel smooth transition auto regression (PSTR) model to analyze the impact of income levels on environmental pollution and identi...

Introducing heterogeneous R&D subsidies into a two-sector technological model, this study investigates the effect of subsidies and directed technologies on environmental quality, and estimates the dynamic process of technological change direction and environmental quality with heterogeneous subsidies on China's auto industry. The results show that...

Using the trans-log cost function and elasticity model, this paper pioneered the analysis of the elasticity and characteristics of the substitution between energy consumption and capital in China's manufacturing industry between 1995 and 2014. Firstly, the research revealed significant differences in the magnitude and direction of the substitution...

This paper depicts the natural gas price control behavior of the Chinese government in an imperfect competition market structure using a static CGE model. It simulates the effect of changes in natural gas price control policy on carbon emission, and the economic effects in view of demand side and supply side. Based on the above, we also analyze the...
