The results of this study are that there are 4 clusters that are formed, namely Cluster 1, there are 2 districts / cities with other potential that have high legitimate PAD, Cluster 2 there is 1 district / city with high potential of Separate Regional Wealth Management Results, Cluster 3 exists 6 Districts / cities with conditions that have very low PAD potential and Cluster 4 have 1 Regency / city with rich Regional Tax and Regional Retribution. The results of the next study were obtained by a constant value of 520031.075, determination coefficient (R2) of 0.188 or 18% with the results of the t-test showing that for X1 the t-value < t-table (0.52422 < 2.412) with sig. (0.60270 > 0.05), X2 obtained the value of t-count < t-table (-1.50343 < 2.412) with sig. (0.13971 > 0.05), X3 obtained a t-count value < t-table (0.38560 < 2.412) with sig. (0.70161 > 0.05), X4 obtained t-count value > t-table (2,97733 > 2,412) with sig. (0.00467 < 0.05) and the results of the F-test obtained by the value of f-count > f-table (3.83542 > 2.61) with the value of sig. (0,00914 < 0,05) means that simultaneously PAD has an effect on Capital Expenditures. Keywords: K-Means, PAD, Regional Wealth, Capital Expenditure
