Unpacking the Impact of E-Commerce Development on Electricity Consumption: Evidence from Chinese Cities

Key findings from this study

• The study found that e-commerce designation significantly reduces urban electricity intensity in Chinese cities.
• The researchers demonstrate that population agglomeration, economic agglomeration, and green innovation constitute key mechanisms linking e-commerce to lower electricity consumption.
• The authors report that government coordination capacity and market efficiency substantially condition the magnitude of e-commerce effects on electricity utilization.

Overview

E-commerce development reduces urban electricity intensity in Chinese cities. The study leverages national e-commerce demonstration city designation as a quasi-natural experiment. A difference-in-differences model quantifies the causal effect on electricity consumption patterns.

Methods and approach

The analysis employs difference-in-differences estimation using national e-commerce demonstration city designation as the policy treatment. Comparison occurs between treated cities and control cities. The approach isolates the causal impact of e-commerce on urban electricity intensity.

Results

E-commerce significantly reduces urban electricity intensity. Three mechanistic pathways mediate this effect: population agglomeration, economic agglomeration, and green innovation. Effect magnitude varies substantially across cities based on local conditions.

Government policy coordination and market efficiency substantially modulate the e-commerce impact on electricity utilization. The effect weakens as the number of pilot cities increases. Saturation of demonstration city programs dilutes the differential treatment effect.

Implications

The findings demonstrate that digitalization can decouple economic activity from electricity consumption growth. Policymakers can leverage e-commerce development as a tool for reducing energy intensity while supporting regional development objectives. Strategic coordination between government intervention and market mechanisms enhances sustainability outcomes.

The heterogeneous effects across urban contexts suggest that universal e-commerce policies require context-specific calibration. Local institutional capacity, governance quality, and innovation ecosystems determine outcome magnitude. As digital economies mature, diminishing returns to pilot program expansion merit consideration in future policy design.
