In this study, we employed the standard-control method.
Every sector was endowed with a different land-use standard
according to the current and the rate of change of its land-use
efficiency. For example, whose current and rate of change of
land-use efficiency were high, will be endowed with a higher
standard than current land-use efficiency relatively. If the actual
land-use efficiency could not reach this standard, the land will
be confiscated so as to improve land-use efficiency.
