while the central and western regions require closed
markets to enhance their economic initiative in China.
The benefits of China's interregional trade are mostly
obtained by developed regions, while the
underdeveloped regions benefit little from such trade,
even suffer damage to varying degrees.
Taking coal, oil and gas, non-metallic mining and
other resource industries as examples, in the input-
output analysis method, through the calculation of
intermediate input rate and intermediate demand rate,
these resource industries are intermediate product
based basic industries, with large intermediate
demand rate and small intermediate input rate. That is
to say, in the development process of these industries,
their dependence on other industries is relatively low.
On the contrary, their products are used as
intermediate inputs of other industries, resulting in
great demand from other industries. During the
development of the coal industry, in addition to the
local production, the use of intermediate products is
more from the purchase from other provinces. In
addition, the products produced by the coal industry
may also flow out, which has not played a real role in
promoting regional economic growth (Xiang &
Meng, 2011).
As China's economy enters a stage of high-quality
development, investment and export can no longer
effectively promote the high-quality development of
China's economy. China has vast territory, and the
division of labor and trade among various provinces
is enough to support high-quality economic
development. However, it is unclear whether, for
resource-rich provinces, inter-provincial trade will
aggravate the local resource curse. Therefore, it is
necessary to clarify the impact of inter provincial
trade openness on regional economic growth, and on
this basis, study whether the development of
resource-based industries is a blessing or a curse to
regional economic growth, and to what extent.
2 VERIFICATION OF THE
IMPACT OF
INTER-PROVINCIAL TRADE
ON THE RESOURCE CURSE
In view of the lack of data on domestic inter-
provincial trade volume, only inter-provincial freight
volume can best represent inter-provincial trade, so
from the inter-provincial freight volume, data from
1997-2019 from 30 provincial regions were used to
re-verify the impact of inter-provincial trade on the
resource curse.
2.1 Model Selection
In order to further analyze the influence degree of
inter-provincial trade in resource industry on regional
economy, this paper constructs the following panel
model to verify the relationship between resource
dependence and economic growth. The specific
formula is as follows:

Y (Economic growth rate) is calculated from the
per capital GDP growth rate. Ed (Resource
development intensity) is measured by the proportion
of energy production to total national production.
Intra (Inter-provincial trade) is measured by the
proportion of inter-provincial railway trade (TL) and
inter-provincial highway trade (GL). Res
(Technology innovation investment level) is
measured by the proportion of financial technology
allocation in total fiscal expenditure. Hum (Human
capital accumulation level) is measured by the
proportion of students in ordinary middle schools. Pe
(Urban private and individual economic development
level) is measured by the proportion of urban private
and individual-employed people in the total number
of people employed. Made (Manufacturing
Development Level) is measured by the proportion of
manufacturing employees in total employment. Fiv
(Material capital investment level) is measured by the
proportion of the total social fixed asset investment in
GDP. Tra (Intensity of opening) is measured by the
proportion of total import and export trade in GDP,
among which the total import and export trade is
converted by the annual exchange rate over the years.
2.2 Test Results of the Whole Sample
First, all models were suitable for fixed effects by F
test, LM test and Hausman test, and then the
endogeneity of the models was tested by DWH test,
which found the endogeneity of models 3 and 4.
Generalized matrix estimation (GMM) can
effectively solve the model endogeneity problem, and
it is more robust. The specific results of the GMM
estimation are detailed in Table 1. The first order
difference perturbation auto-correlation and second
order difference perturbation are unrelated
corresponding to model 3 and 4, and the P value of
Sargan test is greater than 0.1, indicating that the
selection of tool variables is valid. Detailed results are
analyzed as follows:
(1) The resource development intensity
coefficient in model 1 was -0.5056, which is
significant at 1%, indicating that resource
