Penelitian ini adalah tentang pengaruh investasi dan tenaga kerja terhadap pertumbuhan ekonomi di Kabupaten Lahat Propinsi Sumatera Selatan. Tujuan penelitian ini adalah untuk menganalisis pengaruh investasi dan tenaga kerja terhadap pertumbuhan ekonomi di Kabupaten Lahat dan variabel pendorong pertumbuhan ekonomi. Data yang digunakan adalah data sekunder. Data diperoleh dari kantor Badan Pusat Statistik Kabupaten Lahat, Badan Koordinasi Penanaman Modal Daerah Kabupaten Lahat, Bappeda Kabupaten Lahat. Alat analisis yang digunakan regresi. Hasil kesimpulan dari analisis adalah (1) bahwa secara bersama-sama terdapat pengaruh serentak dari ketiga variabel independen (variabel krisis, investasi, peningkatan tenaga kerja dan pertumbuhan PDRBt-1) terhadap pertumbuhan PDRB. Hasil uji F hitung pada tabel sebesar 9,53, p=0,0008, karena p<0,05, maka dapat disimpulkan bahwa model regresi signifikan secara statistik atau hipotesis diterima, terdapat pengaruh serentak dari ketiga variabel independen (variabel krisis, investasi riil, selisih tenaga kerja dan pertumbuhan PDRBt-1) terhadap pertumbuhan PDRB. (2) bahwaterdapat pengaruh investasi terhadap pertumbuhan PDRB. Nilai signifikansi uji t sebesar 0,0002 < 0,05, sehingga hipotesis diterima atau terdapat pengaruh investasi terhadap pertumbuhan PDRB. Nilai koefisien sebesar 0,098 menandakan terdapat pengaruh positif investasi terhadap PDRB, atau ketika nilai investasi meningkat maka diikuti dengan peningkatan nilai pertumbuhan PDRB. Artinya jika investasi naik sebesar 1 miliar, maka akan diikuti naiknya pertumbuhan PDRB sebesar 0,098 miliar.

The results of F-count test of table as much as 9.53, p = 0.0008, because p < 0.0008, so it can be concluded that statistically significant regression model or hypothesis was supported, there was simultaneous effect of three independent variables (variables of crisis, real investment, labor difference and PDRBt-1 growth) on PDRB growth. (2) There was investment effect on PDRB growth. Significant t-test value is 0.0002 < 0.05, so that the hypothesis is supported or there is effect of investment on PDRB growth. Coefficient value of 0.098 indicated that there was positive effect of investment on PDRB, or, if the investment value increased, then, it was followed by increasing PDRB growth value. It means that, if investment increased by 1 billion, it was followed by PDRB growth value of 0.098 billion.
