Sažetak
In consideration of energy and environmental inefficiency brought
about by urban construction, sustainable urbanization has
become a hot issue in recent years. In the process of land urbanization, the source of economic growth can be attributed to technical progress and efficiency improvement. To explore the driving
factors of land urbanization efficiency and its dynamic changes,
the total factor productivity (TFP) and its components of land
urbanization was introduced. The spatial-temporal variations of
land urbanization of Chengyu urban agglomeration in Western
China were estimated by using the Malmquist-Luenberger (ML)
productivity index with undesirable output in this study. Results
demonstrate that: (1) the average TFP of land urbanization
(LUTFP) of Chengyu urban agglomeration in China over time with
carbon emissions (1.029) is 1.2 percent lower than that without
carbon emissions (1.041). Furthermore, the LUTFP with CO2 emissions is lower than the LUTFP without CO2, demonstrating that
land urbanization generates social and economic benefits at the
cost of resource consumption. (2) LUTFP of Chengyu urban
agglomeration under carbon emission constraints presents a generally rising trend in the past ten years and technical progress is
the major source of such growth. Efficiency has become a major
barrier against the improvement of productivity. (3) LUTFP
indexes in Chongqing City and Chengdu plain economic region
are generally higher than those of the south and northeast
Sichuan economic zones. However, LUTFP of different cities tends
to be in equilibrium gradually.
