9.3.2 Analysis of the Relationship Between Export
Competitiveness and Carbon Intensity
To estimate export competitiveness, we use the industrial competitiveness index
(
TC
).

where
X
i
is the export value of certain goods and
M
i
is the import value. The values
of
TC
i
range from
1 to 1. The lower the
TC
i
value is, the weaker the good's export
competitiveness is.
To analyze the relationship between export competitiveness and carbon inten-
sity, we construct a regression model as follows:

tiveness index,
d

is a dummy variable for industries,
β

error term.
9.3.3 Analysis of the Relationship Between Trade Division
and Carbon Intensity
To measure intra-industry trade, this paper uses the G-L(Grubel and Lloyd)index.
IIT

M

Þ= X

(9.6)
where
IIT
i
represents the G-L index,
X
i
is the export value of certain goods, and
M
i
is the import value.
Since the G-L index divides the trade into two parts, intra- and inter-industry
trade, reflecting the relationship between intra-industry trade and general trade, we
use this index to compare diverse industries' trade and the intra-industry trade
of certain industry in different periods. When the value of
IIT
i
is lower than 1,
we regard this as no intra-industry trade. When the value ranges from 0 to 1, we
consider some trade between these two countries is intra-industry trade. If the value
is higher than 1, the trade is completely intra-industry trade.
We construct a regression model to analyze the influence of trade division on
Sino-Japanese carbon intensity:
