Does the Construction of National Eco-Industrial Demonstration Parks Improve Green Total Factor Productivity? Evidence from Prefecture-Level Cities in China

Abstract

This study conducted quasi-natural experiments based on the panel data of 239 prefecture-level cities in China from 2005 to 2017. The difference-in-difference (DID) and mediation effect model are used to test the impact and mechanism of the construction of national eco-industrial demonstration parks (NEDP) on green total factor productivity (GTFP). The results show that: (1) The construction of NEDP has significantly improved the urban GTFP, and the conclusion is still valid after running the robustness test. (2) Mechanism analysis shows that the construction of NEDP has improved GTFP through technological innovation and industrial structure upgrading. (3) The heterogeneity results reveal that NEDP has a significant positive effect on GTFP in the central and western regions, while the effect was insignificant in the eastern region. Moreover, NEDP significantly contributes to GTFP in resource-based and non-resource-based cities, while the contribution of resource-based cities is greater than that of non-resource-based cities. This study provides a reference for China to further promote the construction quality of NEDP and green development.

A Study on the Influence of Green Industrial Policy on Urban Green Development: Based on the Empirical Data of Ecological Industrial Park Pilot Construction

“…It can be seen that OLS regression results do not change the basic conclusions of the bidirectional fixed effect model. In sum, the implementation of the pilot policy of eco-industrial parks can significantly promote the urban green development of cities, with an increase of about 0.0279 units, which coincides with the conclusion of existing studies [60,63]. The eco-industrial park is a new type of industrial park based on the requirements of clean production, the concept of the circular economy, and the principles of industrial ecology, seeking the mutual promotion of economic and environmental benefits.…”

“…Based on industrial ecological design, eco-industrial parks are conducive to decreasing pollutant emissions and realizing resource recycling, thus facilitating green and sustainable economic development. Eco-industrial parks are a scientific way to realize green industrial transformation and green economic development [60]. The construction of eco-industrial parks can train an ecological industrial network system by reasonably planning an industrial chain, and realize the regional sustainable green development of coordinated environmental protection and economic growth.…”

Environmental regulation, agricultural green technology innovation, and agricultural green total factor productivity

“…In addition, restricted by the level of economic development, there may be regional variations in how environmental legislation affects the development of agricultural green technologies and the productivity of agricultural green total factors (Liu et al, 2021a). Specifically, Investment in resources is crucial for the development of agricultural green technology.…”

How Multi-Dimensional Local Government Competition Impacts Green Economic Growth? A Case Study of 272 Chinese Cities

“…Green economic growth (GEG). Based on the calculation method of Yang et al (2021d) and Liu et al (2021), we apply the research framework of non-radial SBM including unexpected output to characterize GEG. GDP at the prefecture-level, which is discounted using 2004 as the base period, is employed as the desired output.…”
