What Type of Industrial Agglomeration Is Beneficial to the Eco-Efficiency of Northwest China?

Abstract

The contradiction between industrial economic development and the ecological environment in Northwest China is prominent, so the green transformation of industrial economy in this region is imperative. From the perspective of industrial ecology, this study uses economic and environmental statistics from Northwest China from 2006 to 2018 as well as the Krugman specialization index and entropy index methods to calculate the degree of different types of industrial agglomeration in Northwest China. The eco-efficiency of Northwest China is calculated by the global SBM-DDF model. On this basis, the stochastic effect panel tobit regression model is used to analyze the influence and mechanism of different types of industrial agglomeration on eco-efficiency in Northwest China. The results show that the concentration of specialization has a significantly negative effect on the eco-efficiency of Northwest China at the level of 1%. Excepting Ningxia, the eco-efficiency of other provinces has been improved with the decrease of industrial specialization. The influence of the related diversification agglomeration on the eco-efficiency in Northwest China shows a U curve. The degree of industrial correlation diversification in Qinghai and Ningxia is less than the critical value 1.45, whereas Shaanxi, Gansu, and Xinjiang have crossed the inflection point. The unrelated diversification agglomeration has a negative effect on the eco-efficiency of Northwest China at the level of 1%, and the degree of industrial independent diversification in Shaanxi Province has decreased slightly, which is beneficial to the improvement of eco-efficiency. By contrast, other provinces have increased considerably. The conclusion can provide a theoretical basis for industrial green transformation path selection and related policy formulation in Northwest China.

The “Pollution Halo” Effect of FDI: Evidence from the Chinese Sichuan–Chongqing Urban Agglomeration

“…With the comprehensive development of the social economy, people tend to make higher demands regarding environmental quality, influence the government's environmental regulation, and influence the production and pollution behavior of enterprises through their consumption preference and the pressure of public opinion [19]. Further, the process of urbanization produces positive externalities, thus reducing environmental damage through economies of scale, the agglomeration effect, the resource reallocation effect, and so on [57][58][59]. Compared with social and economic factors, natural factors play a more stable role in the influence of FDI on PM 2.5 pollution in the Sichuan-Chongqing urban agglomeration.…”

The Impact Factors and Spatial Spillover of Industrial Green Development: Based on Cities in the Northwest Segment of the Silk Road Economic Belt

“…where given in (7), the relative closeness of the ideal solution of the evaluation object C i is calculated as follows:…”

“…Additionally, the Green Development Index System was also released in the same year [6]. However the resource-rich northwestern region of the Silk Road faces significant contradictions between economic development and industrial greenization due to its high dependence on industrial development [7]. This could lead to a lack of applicability of the nationwide indicator system in the northwest region.…”

Evaluation of Ecological Environment Effect of Villages Land Use and Cover Change: A Case Study of Some Villages in Yudian Town, Guangshui City, Hubei Province

“…In terms of research content, the ecological environmental effect evaluation is consistent with the research on ecological security and ecological risk. This is divided into two different dimensions based on patterns and processes that correspond to the changes in the static distribution and dynamic evolution process of each component in the ecosystem caused by external pressure [36].…”
