Penelitian ini bertujuan melihat keberpihakan pertumbuhan ekonomi terhadap kelompok miskin di Provinsi Banten, DKI Jakarta dan Jawa Barat selama 2006-2010. Model regresi spasial dengan maximum likelihood estimation diterapkan untuk data panel dari 40 kabupaten/kota. Penelitian membuktikan keberadaan autokorelasi spasial pada variable pertumbuhan ekonomi, ketimpangan pendapatan dan kemiskinan pada taraf yang signifikan. Perhitungan pro poor growth index menggunakan kriteria poverty severity index menunjukkan bahwa pertumbuhan ekonomi telah berpihak kepada kelompok miskin. Meskipun demikian, pengurangan keparahan kemiskinan ditopang seluruhnya oleh pertumbuhan ekonomi, sedangkan perubahan distribusi pendapatan justru memperburuk tingkat keparahan kemiskinan.

This study examines the economic growth bias against the poor in the province of Banten, Jakarta and West Java during 2006-2010. Spatial regression models with maximum likelihood estimation is applied to panel data from 40 districts / cities. Research proves the existence of spatial autocorrelation on the variable of economic growth, income inequality and poverty on a significant level. Pro-poor growth index calculation using the poverty severity index criterion shows that economic growth has been pro-poor. Nevertheless, the severity of poverty reduction is sustained entirely by economic growth, while changes in income distribution has worsened the severity of poverty.
