China’s Low-Altitude Economy Shows Nonlinear Effects on Pollution and Carbon Reduction

An open-access study published in Carbon Balance and Management examines how the emerging low-altitude economy—an industrial paradigm built around activities in low-altitude airspace—affects pollution and carbon emission reduction across China. Using panel data from 28 Chinese provinces covering the period 2008 to 2023, the research systematically analyzes the relationship between low-altitude economic policy intensity and regional environmental outcomes, along with the mechanisms underlying that relationship.

The central finding is that the impact of low-altitude economy policy intensity on pollution and carbon emission levels is nonlinear rather than monotonic. The study estimates an empirical transition point of approximately 2.896, meaning the environmental effect of policy intensity changes direction or magnitude as intensity crosses this threshold. This stage-dependent pattern suggests that simply escalating policy support does not translate linearly into cleaner outcomes.

The mechanisms behind this nonlinear pattern involve two channels moving in different directions. According to the findings, low-altitude economy policy intensity first weakens and then strengthens environmental regulation, while its promoting effect on green innovation gradually diminishes over time. The interplay of these two dynamics—regulation that changes strength across stages and innovation effects that fade—shapes the overall pollution and carbon emission reduction effects observed in the data.

Physical infrastructure appears to matter for how quickly regions realize environmental benefits. The study reports that a stronger low-altitude airspace flight foundation accelerates the crossing of the turning point and strengthens the environmental benefits associated with low-altitude economic development. In other words, provinces with more developed flight infrastructure reach the favorable side of the nonlinear transition sooner.

Spatial effects are uneven across the country. The analysis identifies heterogeneous transitions in the marginal environmental effects of low-altitude economy development during key development stages in provinces including Sichuan, Jilin, Shaanxi, and Zhejiang. This provincial-level variation indicates that the environmental consequences of the low-altitude economy cannot be generalized uniformly across China’s regions.

Spatial transformation is also asymmetric. The study finds stronger pollution and carbon reduction effects in regions with better ecological endowments or higher climate risk exposure. This asymmetry implies that geographic and environmental conditions condition how much emissions benefit a region can obtain from developing low-altitude economic activity, rather than the effect being uniform nationwide.

Beyond policy and spatial dimensions, the research incorporates social and market signals. Public attention to the low-altitude economy and carbon market returns exhibit a negative risk resonance over short-to-medium-term horizons, specifically at time scales of 100 to 150 days, corresponding to 12 to 24 cycles.

Taken together, the results reveal stage-dependent and spatially differentiated environmental consequences of the low-altitude economy. The authors position these findings as new evidence for understanding the carbon-management implications of emerging spatial economic activities, framing the alignment between low-altitude economy policy regulation and regional pollution and carbon reduction achievements as critical for promoting industrial green transformation and sustainable development.

The study is published as open-access research in Carbon Balance and Management, with the article shared early to provide faster access to peer-reviewed, accepted research carrying a permanent DOI. Because the analysis is based on provincial panel data through 2023, the reported transition point, mechanism estimates, and spatial patterns describe observed associations within that dataset and period, and the identified provincial heterogeneity underscores that conclusions for any individual region depend on local development stage, ecological endowment, and risk exposure.
