  The energy trade is an important pillar of each country's development, making
up for the imbalance in the production and consumption of fossil fuels.
Geopolitical risks affect the energy trade of various countries to a certain
extent, but the causes of geopolitical risks are complex, and energy trade also
involves many aspects, so the impact of geopolitics on energy trade is also
complex. Based on the monthly data from 2000 to 2020 of 17 emerging economies,
this paper employs the fixed-effect model and the regression-discontinuity (RD)
model to verify the negative impact of geopolitics on energy trade first and
then analyze the mechanism and heterogeneity of the impact. The following
conclusions are drawn: First, geopolitics has a significant negative impact on
the import and export of the energy trade, and the inhibition on the export is
greater than that on the import. Second, the impact mechanism of geopolitics on
the energy trade is reflected in the lagging effect and mediating effect on the
imports and exports; that is, the negative impact of geopolitics on energy
trade continued to be significant 10 months later. Coal and crude oil prices,
as mediating variables, decreased to reduce the imports and exports, whereas
natural gas prices showed an increase. Third, the impact of geopolitics on
energy trade is heterogeneous in terms of national attribute characteristics
and geo-event types.
