Maqolada Surxondaryo viloyati kesimida transport tarmog‘i va iqtisodiyotning asosiy tarmoqlari (qurilish,
qishloq xo‘jaligi, sanoat) o‘rtasidagi bog‘liqlik Bosh komponentalar usuli (PCA) orqali modellashtiriladi. Standartlashtirilgan
ko‘rsatkichlardan hosil qilingan 〖PC〗_1— “umumiy tarmoqlararo o‘sish indeksi” transport xizmatlari hajmidagi
variatsiyaning katta qismini izohlaydi, multikollinearlik muammosini bartaraf etadi va sektorlararo sinergiyani miqdoriy
baholashga imkon beradi.
