is assigned to every attribute in each category according to standardized
criteria. This value is a figure between 0 and 10 (0 for least desirable and 10
for most desirable). Based on the value assigned and the weighting of the
attribute, a figure (e.g., X) is reached. Adding up these figures for every
attribute in the same category, a new figure is derived (e.g., Y). Based on the
weighting of that particular category, a percentage of Y (e.g., Z) is derived.
The final figure, Z, is calculated for all categories, and an overall score is
derived. This overall score is then matched against a set of grades, AAA, AA,
A, BBB, BB, B and C, which are the possible ratings given for industrial parks.
It is a straightforward
matter to assign values for attributes such as GDP and fixed asset investment.
The values for attributes such as accessibility and efficiency, which are more
difficult to evaluate, rely on China Knowledge’s on-site studies and
interactions with the relevant administrative bodies. Media reports are also
used as reference points.
