China’s Provincial Environmental Efficiency Evaluation and Influencing Factors of the Mining Industry Considering Technology Heterogeneity

Abstract

The mining industry has promoted the process of industrialization in China, and the current consumer demand for mineral products is still very large. Since the development of mineral resources has caused serious environmental pollution and waste of resources, the country has raised the development of green mining to a strategic level. Based on China's provincial data over the 2007-2016 period, this paper measured environmental efficiency (EE) of China's mining industry (CMI) using Meta-frontier slacksbased measure (SBM) method and reveals the root causes of environmental inefficiency (EI). Then, a panel Tobit regression model was established to discuss the differential impact of relevant factors on the metafrontier environmental efficiency (MFEE) of CMI in the regional heterogeneity perspective. The results show that: (1) The MFEE of CMI exhibits low score and there is significant regional heterogeneity, with the highest in Eastern China, followed by Central China, and Western China. (2) The technology gap ratio (TGR) in the three regions shows that Eastern China ranks the highest, followed by Central China, and Western China. TGI is the main contributor to the EI of CMI. (3) the overall MFEE of CMI, the MFEE of CMI in Eastern, Central and Western area are negatively related to the environmental regulation intensity, are positively related to the resource utilization rate, respectively. The economic development level, innovative ability, education level, industrial structure and state-owned capital proportion differently effect on China's overall EE of the mining industry and the EE of the mining industry in different regions of China, respectively.

[Retracted] How to Evaluate the Efficiency of Green Economy and Its Regional Differences: Evidence from China

“…For example, Chen Fang et al used "carbon emissions" as single nonexpected output index to measure the green economic efficiency of all provinces in China [12]. Xia Yongqiu et al used the SBM to calculate China's green economic efficiency by taking the industrial three wastes emission index as multiple undesired outputs and discovered that the national average annual green economic efficiency was 0.7, yielding an inverted U-shaped evolution process [13].…”

The Recent Ecological Efficiency Development in China: Interactive Systems of Economy, Society and Environment

“…It is probably because the western region of China has a weak industrial foundation, a single industrial structure and lagged high-tech industries (Zhang et al, 2020;Chen et al, 2021a). Moreover, the ecological environment in the western region is fragile (Xia et al, 2020). These objective factors make the EE in the western region vulnerable to external shocks (such as environmental regulation), resulting in a significant decline of EE in this region in the early stage of this research.…”

Does Technological Innovation Efficiency Improve the Growth of New Energy Enterprises? Evidence from Listed Companies in China

“…Because the technical inefficiency term is introduced into the stochastic frontier method [75], it is necessary to set its functional equation. By analyzing the factors affecting the technological innovation output of new Chinese energy enterprises, and referring to the research of Lin et al [76], Qiao et al [77], Xia et al [78], and Ma et al [79], the profitability, government support, and the proportion of state-owned capital are selected as environmental variables. The inefficiency term is set as follows:…”
