The Belt and Road Initiative (BRI) has been implemented for over a decade; however, research on its impact on China’s transport sector remains relatively scarce. It is imperative to investigate whether the BRI has greatly enhanced the growth of Green Total Factor Productivity (GTFP) in the transport sector across provinces along its route because the logistics hub is crucial for sustainable land development of the local economy. To address this missing link, this study examined the GTFP of the transport sector in cities along the BRI by employing the global Luenberger nonradial directional distance function (GLNDDF). Subsequently, a Difference-in-Differences (DID) model was applied to evaluate the policy impact of the BRI on the regional GTFP of the transport sector. The key results of this study were as follows: (1) our empirical findings indicated that the BRI has a statistically significant, yet very weak governance of the GTFP of the transportation sector, with an average increase of 0.0265 units in total factor productivity, implying that the direction of the BRI seems right, but much stronger governance is needed for differentiated city planning; (2) the BRI has two wings in its implementation policies and regulatory and promotional policies. In this study, active environmental regulation may have a more substantial impact than promotional policies, implying that oversupply issues arising from financial promotions along the BRI routes should be avoided for city planning, even with its political importance. (3) There are notable regional variations, with the policy effect being relatively weak in the central region, implying that the grand industrial transition from the east coastal cities to the western region should be cautiously harmonized between market demand and infrastructure-oriented government-led policies. These findings provide valuable insights into urban environments, city planning, and urban–rural interactions, emphasizing the importance of land-related tradeoffs in resource management to foster sustainable governance in developing countries.

Theoretically, regions with rich natural resources often tend to develop resource-based industries more intensively, resulting in resource-dependent land development. China’s resource-dependent cities exhibit certain exceptions. Natural resource dependence (NRD) plays a relatively positive role in the total factor productivity change (TFPCH) in these cities, primarily attributable to their relatively mature technological efficiency. However, while such positive impacts exist, their overall effect remains limited. Many resource-based cities in China still face challenges in achieving sustainable growth. This raises a key question: why have some resource-based cities failed to achieve sustainable development? In order to explore the root cause of this problem, this paper systematically analyses the impact of resource dependence on TFPCH, and its governance mechanism based on the balanced panel data of 112 resource cities in China from 2003 to 2021, using the Super-SBM-DEA-Malmquist index method in the first stage, and the OLS model in the second stage. The main findings of this paper are as follows: First, NRD has a significantly positive impact on TFPCH, especially in growing and regenerating cities. The empirical results further validate the applicability of the resource blessing theory in China. Second, government regulation has a dampening effect on TFPCH in resource cities, which suggests that in the future development of resource cities, government intervention should be moderately reduced, and more emphasis should be placed on stimulating the city’s own autonomous mobility and endogenous development drive. Third, heterogeneity analyses show that this promotional effect is mainly realized through the improvement of technical efficiency. Fourth, the analysis of the moderation effect shows that research and development (R&D) intensity plays a positively moderating role in the sustainable development of resource-based cities. Through a stepwise approach, this paper reveals why resource-based cities cannot achieve sustainable development. The level of R&D in some resource-based cities remains relatively low, while it is the key factor for the applicability of the resource blessing (RB) hypothesis in China’s resource city. The findings not only provide new perspectives for theoretical research, but also important policy recommendations for the sustainable governance of land use in resource-based cities worldwide.

The Swedish Paradox is a well-known phenomenon related to high research and development (R&D) investment with supposedly low aggregate economic performance owing to economic saturation. The Korean economy has not yet become an advanced economy; however, its R&D performance is negligible. Recently, also the R&D share of the GNP has become much higher, and its contribution to the economic growth rate is rapidly decreasing, implying a negative relationship between R&D activities and economic performance. This study uses slacks-based data envelopment analysis to investigate investment performance at the local government level in Korea. Our findings reveal that the average score for R&D investment performance in Korea is 64%, indicating huge potential for an efficiency enhancement of 36%. Notably, among the 16 local governments examined, Seoul and its surrounding metropolitan areas showed the lowest R&D efficiency, while Gangwon and Gwangju exhibited superior performance. Since these two regions have promoted specific missions, such as the medical hub in Gangwon and the optical fiber strategic platform in Gwangju, precise and accurate differentiation appears necessary to avoid a lack of governance. To determine the workable mechanism of R&D support policies, we further divided R&D productivity into three categories by incorporating the Malmquist Index (MI). The paper productivity of R&D shows an increasing trend over the experimental period from 2016 to 2021. However, overall, the MI shows slightly deteriorating productivity with 0.978, owing to the aggravating effect of patents and commercialization of R&D. The success in the paper comes from the harmonized partnership between the strong push factor of the government and voluntary pull factor of the R&D support receiving universities. Thus, we suggest that the Korean government should not depend on the superficial effectiveness of R&D in the term but on public–private partnerships with stronger performance-oriented responsibility.

Like many countries, China’s airports faced severe operational challenges after the COVID-19 outbreak. However, this predicament has been better mitigated by the Chinese government’s strong support for the aviation industry. However, whether this supportive policy can ensure the sustainable development of the industry needs to be further evaluated. In order to better understand the role of government promotional policies, this paper attempts to explore the driving mechanisms behind the sustainable development performance of Chinese airports. Using the bootstrap Data Envelopment Analysis (DEA) methodology, this study evaluates the operational efficiency of 43 major airports over the period from 2015 to 2022. The efficiency scores are compared with the regional distributions of supply and demand factors, as well as the different sizes based on their annual passenger throughput. The overall operational efficiency showed a fluctuating trend of an initial increase followed by a decline due to COVID-19, with significant regional disparities in airport efficiency. Regional differences are evident, with the eastern region having the highest efficiency value of 0.719, while the central region has the lowest efficiency of 0.594. The findings show that airports in the eastern region perform the best due to the proactive market support with rapidly increasing logistics demand, while airports in the west and northeast regions supported by the strong promotional policies follow closely in terms of operational efficiency. In contrast, airports in the central region are much less efficient due to the lack of market or policy support. To analyze more precisely this conflict on the governance, further analyses show that airport size also has a significant impact on the operational efficiency. Larger airports are typically more efficient, while smaller airports are less efficient, implying the market demand is slightly better to promote the airport operational efficiency than the promotional policies. These findings help us to gain a deeper understanding of the mechanism in the sustainable governance behind the operational efficiency of airports and suggest that more market-oriented appropriate policy direction is required to enhance the competitiveness of the aviation industry. These findings offer valuable insights for policymakers and stakeholders of the developing countries as well, underlining the necessity not for supply-driven policies, but for the demand–pull efforts to optimize resource allocation and adapt to evolving market dynamics.

The Belt and Road Initiative (BRI) proposed by China in in 2013 prioritizes environmental sustainability and regional economic development from a global perspective. Although the BRI has achieved considerable economic progress in many cities and regions, research on its environmental impacts is still insufficient, with limited attention paid to domestic urban areas in particular. Existing studies have focused primarily on carbon emissions, ignoring the broader environmental impacts of industrial emissions, such as those from smart transportation. To address this gap, this study adopts four major pollutant emissions—carbon dioxide (CO₂), industrial particulate matter, industrial sulfur dioxide (SO₂), and industrial wastewater emissions—as indicators to assess pollution levels in urban environments. Adopting panel data from 281 Chinese cities from 2003 to 2021, this study employs the difference-in-differences (DID) method to estimate the effect of the BRI on urban environmental pollution. This study is based on the following hypotheses: Hypothesis 1. BRI implementation has reduced urban pollution emissions. Hypothesis 2. Advancements in science and technology will drive the implementation of the BRI. Hypothesis 3. A proactive government response can significantly reduce urban environmental pollution. The main findings of this study are as follows. First, BRI implementation significantly reduces urban environmental pollution by 1.05%. Second, the policy effects of the BRI are more pronounced in the eastern and western regions and in larger cities, implying that geopolitical- and market-oriented strategies are important for regional performance. Third, scientific and technological progress positively affects pollution reduction in urban environments. Fourth, the BRI contributes to strengthening government intervention, which subsequently improves sustainable governance, reduces urban environmental pollution, and promotes regional economic cooperation. Our findings will serve as a crucial reference for future policymaking endeavors toward eco-friendly logistics cooperation in the region.

Amid intensifying geopolitical tensions and global uncertainties, regional economies face mounting pressures that threaten both stability and sustainability. Against this backdrop, building resilient regional systems has become a central issue in sustainable urban development. As a key driver of resilience, innovation has been central to China’s development agenda. Continuous and large-scale R&D investment has redirected focus from input expansion to efficiency improvement, positioning R&D efficiency at the heart of resilience-building. Under external shocks and uncertainty, can improvements in R&D efficiency enhance regional economic resilience? If so, which additional factors embedded in sustainable urban development planning can further amplify this effect? To address these questions, this study employs provincial panel data from 2000 to 2021 and integrates the SBM-DEA approach with an entropy-weighted resilience index for regression analysis. The results indicate that (1) R&D efficiency exerts a positive but limited impact on resilience, with an average increase of only 0.188 units, indicating that efficiency alone cannot generate resilient economies without institutional coordination; (2) human capital agglomeration and financial density strengthen this relationship, highlighting the need to integrate talent and financial strategies; (3) the positive effect is observed in eastern provinces but remains insignificant in central and western regions, revealing pronounced structural disparities that risk widening the resilience gap across regions rather than fostering balanced development; and (4) targeted government intervention effectively converts innovation efficiency into resilience gains, fostering coordinated and sustainable development. This study empirically demonstrates that improving R&D efficiency significantly enhances regional resilience in China and based on this evidence introduces the ICT Synergy Framework as a novel analytical lens for understanding how innovation, capital, and talent jointly drive resilience and sustainable development. The findings further suggest that targeted government intervention in R&D resource allocation can reinforce resilience, offering broader lessons for other developing economies. By integrating innovation outcomes with spatial and institutional planning, the study provides actionable insights for advancing sustainable urban development and coordinated regional growth.
