The asymmetric effect of public private partnership investment on transport CO2 emission in China: Evidence from quantile ARDL approach

Abstract

Transportation infrastructure is a pillar of economic development as well as a main contributor to climate change. Therefore, it is necessary to transform the transport sector investment into climate-resilient, low-carbon transportation choices in order to achieve sustainable transportation infrastructure. In case of China, this transformation might be necessary from the perspective of the "New-style Urbanization" strategy, and for fulfilling this strategy, policy realignment is required. To address this policy-level void in the literature, we explore the influence of public private partnerships investment in transport sector, renewable energy consumption, urbanization on transport-induced carbon emissions in China. For this purpose, we apply Quantile Autoregressive Distributed Lagged (QARDL) method during 1990Q1-2018Q4. Based on the results of the study, a multipronged sustainable development goal (SDG) framework has been suggested, under which SDG 11, SDG 13, and SDG 8 are addressed, while using SDG 17 as a vehicle.

RETRACTED ARTICLE: The role of public-private partnership investment and eco-innovation in environmental abatement in USA: evidence from quantile ARDL approach

“…It is quite evident to explore various studies on the relationship between ecological innovation and environmental degradation (Amen et al 2021 ; Anwar et al 2021a ; Chen et al 2019 ; Chen et al 2018 ; Cheng et al 2019 ; Cho et al 2015 ; Ding et al 2021 ). These studies have provided their significant contribution while exploring the trends in ecological or green innovation along with their impacts or relationship with the environmental factors like carbon emission, greenhouse gas emission, and haze pollution as well (Li et al 2018 ; Sun et al 2019 ; Zhang et al 2019b ).…”

“…Furthermore, PPPI along with GDP are causing more consumption-based CO2 emission and similar is observed in the long-run estimation as well. Anwar et al ( 2021a ) consider the asymmetric effect of PPPI on the transport carbon dioxide emissions in China through QARDL approach. However, under long-run estimation, their study observes a significant and negative relationship between CO2 emission and PPPI for the higher-level quantiles.…”

“…The present study is quite different and investigates the impact of public-private partnership investment, eco-innovation, and economic growth on the environmental abatement in the USA by using QARDL. Furthermore, another recent study conducted by Anwar et al ( 2021a ) and examined the asymmetric effect of public-private partnership investment on transport CO2 emission in China by using QARDL. Similarly, the present study is the extension of past study such as Anwar et al ( 2021a ) and investigates the impact of public-private partnership investment along with eco-innovation and economic growth on the environmental abatement in the USA by using QARDL.…”

Additionally, Suki et al ( 2020 ) also used the QARDL to analyze the globalization (including overall, social, economic, and political) impact on the ecological footprint in Malaysian.…”

Research on the Relationship between Transport Infrastructure and Performance in Rail and Road Freight Transport—A Case Study of Japan and Selected European Countries

“…In their contribution [19], the Polish researchers Kowalski and Wiśniewski pointed out that investments affect changes in transport accessibility and mobility, as well as resulting in changes in traffic flows. Further research has been carried out in China to determine the impact of motorway construction and regional interconnections on GDP, the environment, and CO 2 emissions [20,21].…”
