The purpose of the study was to determine the effect of increasing expenditure and increasing the minimum wage of the government in the simultaneous model of the industrial sector of DKI Jakarta province. The estimation model in the simultaneous model of the industrial sector of DKI province uses the 2 SLS (Two-Stage Least Squares) method. The simulation results of a 10% increase in the expenditure of the provincial government of DKI has resulted in an increase of investment of 4.72%, production growth of 0.19%, employment of 0.17%, an increase in production costs by 0.24%, and company profits increased by 0.10%. On the other hand, the simulation results of a 10% increase in the provincial minimum wage has resulted in a decrease in labor absorption by 0.55%, a decrease in production in the industrial sector has resulted in 0.21%, a decrease in investment by 0.07%, and a decrease in production costs by 0.04%.

To analyze the increase in government spending and expenditure as well as exports of Special Region of Yogyakarta (DIY)'s mainstay commodities by 10% each to DIY's GRDP in a historical forecasting simulation and to analyze this increase against other variables in the model other than DIY's GRDP. The model of government spending and expenditure as well as the export of the mainstay commodity of DIY is formed by the form of a simultaneous equation system. The system describes the behavioral and identity equations of all endogenous and exogenous variables in the hope of producing parameter estimators that are theoretically and empirically appropriate. The developed model is dynamic by entering the endogenous Lag (L) variables into the behavioral equation. The increase in government spending and expenditure and an increase in DIY exports by 10% each can increase DIY's GDP by 9,608 IDR (million IDR) or a change of 0.60%. This increase led to an increase in regional and foreign investment by 72,042 IDR (million IDR) or 8.96%, employment of 16027 people or 1.11%, an increase in the value of technology 7,662 IDR (million IDR) or 5.23%, and the number of businesses 21 units or 0.55%.

Strategi pembangunan di Kabupaten Minahasa Utara ditunjukkan oleh kinerja ekonomi melalui pertumbuhan Produk Domestik Regional Bruto (PDRB), lapangan usaha, dan kesempatan kerja. Kontribusi lapangan usaha pada PDRB dicapai melalui faktor tenaga kerja dan modal. Besaran produktivitas tenaga kerja dan modal menjadi ukuran kontribusi tersebut dengan mengukur besaran Location Quotient (LQ). Tujuan penelitian adalah menentukan besaran produktivitas tenaga kerja terhadap PDRB setiap lapangan usaha, menentukan besaran target produktivitas modal terhadap PDRB lapangan usaha, dan optimasi faktor modal untuk mengatasi dampak eksternalitas negatif dari sampah dan limbah buangan. Lapangan usaha Pertanian, Kehutanan, dan Perikanan serta Pertambangan dan Penggalian menjadi andalan di Kabupaten Minahasa Utara. Rekomendasi untuk produktivitas modal lapangan usaha adalah pengadaan listrik dan gas, pengadaan air, pengelolaan sampah dan limbah. Investasi modal pengadaan teknologi mesin dapat dicapai melalui kerja sama antar pihak swasta dan Pemerintah Daerah dengan melibatkan perguruan tinggi untuk mencapai hasil yang optimal.
