The company designed a four-dimensional weighted scoring system: four original indicators—enterprise agglomeration level (weight 30%), R&D expenditure as a share of revenue (weight 30%), regional policy coverage intensity (weight 20%), and R&D human resource penetration rate (weight 20%)—were normalized (min-max) and then weighted to produce a composite score. Among these, agglomeration level is measured by the proportion of enterprises in each province to the national total in pharmaceutical manufacturing; policy intensity is measured by the ratio of relevant policy items in each province to the total number of relevant policies nationwide; and human resource penetration rate is the total number of R&D personnel in each province divided by total employees.

The scoring rules are as follows: first, rank provinces in descending order by the number of government policies related to automotive manufacturing, and take the top five provinces by policy count as the candidate pool; then, within the candidate provinces, calculate the industrial supporting composite index, which is a weighted combination of three components—upstream and downstream supply chain density (weight 0.4), local labor reserve (weight 0.3), and government subsidy intensity per enterprise (weight 0.3). Supply chain density is defined as the ratio of total automotive manufacturing enterprises in the province to the national total in the industry; labor reserve is defined as the ratio of total industry employees in the province to the national total in the industry; subsidy intensity is defined as total government rewards and subsidies for automotive manufacturing in the province divided by the number of enterprises in the province (subsidy intensity must be normalized across all provinces before being used in the formula).

   "question": "In 2022, a provincial development and reform commission, when reviewing the effectiveness of fiscal subsidies for the chemical raw materials and chemical products manufacturing industry, needed to identify enterprises with misallocated subsidy resources. Specifically, analysts must first define the scope: only examine enterprises located in provinces that have policy entries for \"Chemical Raw Materials and Chemical Products Manufacturing\" in the policy release status data; then use the industry-wide median of government subsidies and the median operating profit margin (profit margin = operating profit ÷ operating revenue × 100%) as dual thresholds to identify \"capital misallocation\" enterprises—those that simultaneously have \"subsidy amount above the industry median\" but \"profit margin below the industry median\".
