Abstract
Urban
green
technology
innovation
(UGTI)
is
strongly
tied
to
environmental
regulations,
which
can
successfully
balance
economic
and
benefits.
Selecting
the
panel
data
for
280
Chinese
cities
during
2006–2019,
we
take
energy
saving
emission
reduction

city
policy
as
a
quasi-natural
experiment,
then
employ
difference-in-differences
model
examine
effect
its
mechanisms
of
ESER
on
UGTI.
Empirical
results
show
that
significantly
promote
UGTI,
especially
in
western
region,
northern
with
weak
government
attention.
At
same
time,
China’s
has
stronger
promoting
UGTI
where
targets
are
more
stringent.
Mechanism

two
channels:
increasing

addition,

The
findings
not
only
enrich
