| Abstract: |
| This paper mainly discussed the contribution of cultivated land occupied by construction to
Guangdong economy growth，like the features of different time sections and the difference among four economic
regions from the reform and open policy. Referring to the theory of economic growth，by establishing inputoutput
model and based on the relevant data during 1978-2014 in Guangdong，the contribution of cultivated land
occupied by construction to Guangdong economic growth was quantitatively analyzed in different time sections as
well as different special regions. The time-section analysis results show that compared with the average values
（from 1978 to 2014），there is no longer positive relevance between the contribution of cultivated land occupied
by construction and Guangdong economic growth，while the capital and technology have gradually become driving
forces of economic growth in Guangdong， such as the contribution of capital input increases from 0.286% to 0.356%
and the contribution of technology advance increases from 0.196% to 0.233% as well. The above indicates that the
contribution of cultivated land occupied by construction to Guangdong economic growth has gradually been declined
and long-term decoupling between the economic growth and cultivated land occupied by construction is inevitable， thus，there is no fundamental contradiction between maintaining economic growth and protecting the red line of
cultivated land. The special regional analysis mainly shows that the contribution of cultivated land occupied by
construction to the regional economic growth of the Pearl River Delta region appears to be 0.379%，which is less
than that of the East and the west of 0.677%，0.422%，and that of the northern mountainous areas is not obvious.
Therefore，presupposed by strictly adhering to the red line of cultivated land，the developed areas should speed up
the upgrading of industrial structure，and the less developed areas should develop a scientific and rational land use
planning，thus improving the output capacity of unit land resources and urging regional economic equilibrium and
sustainable development in Guangdong. |
