Abstract

This study aims to investigate the effects of FDI spillover on labor productivity of the firms in the five priority manufacturing sector industries in Indonesia, namely food and beverages, textiles, wearing apparel and footwear, chemicals and pharmaceuticals, electronics, and automotive and transport equipment industries. Using unbalanced firm-level data from 2000 to 2015, we find positive spillover effects in the horizontal linkages, which measure the presence of foreign firms on the labor productivity of local firms in the same industry. However, the effects of FDI on the labor productivity of domestic in backward linkages shows negative results, which means foreign buyers fail to give benefits to domestic suppliers. Moreover, the relationship between foreign suppliers and domestic buyers in the forward linkages also show negative spillover effects. These findings are also in line when the analyses are disaggregated into each industry, except for the electronics industry. Based on the different results of the three linkages of spillover effects, our findings suggest that the FDI spillover has not provided comprehensive benefits for local firms.

Abstract

The CNC finish milling of wood-based materials creates chips in a wide size range, where considerable amounts were found even below <10.0μm. The presented article studied the effect of technological variables on determined amounts of chips in dust sizes and respirable range from medium-density fibreboards (MDF) and particleboards (PTCB). The materials were milled at a constant width of cut (ae) by 1mm, with the feed speed (vf) in the range of 6, 8, 10, and 12m·min-1, and with revolutions of the cutting tool (n) in the range of 16,000; 18,000; and 20,000revs·min-1. In dust size, we cover chips in the size range below <0.125mm, and respirable size below <10.0μm. The dust sizes from collected chip samples were determined by sieve analysis with pre-defined mesh sizes by weighting the retained mass on specific sieves and with the laser analysis we estimated the amounts of chips in sizes <10.0μm. The number of chips in the dust size ranged for MDF by 34.7-40.8w% and in PTCB by 38.1-54.7w%. Amount of chips in respirable size for MDF by 0.01-18% and for PTCB by 0.01-4.5% of the total mass volume. Increasing the (vf) from 6 to 12m/min significantly lowered amounts of Fine and chips in respirable size (p<0.05) in PTCB, no matter on adjusted cutting tool (n). In MDF such effect was observed only with (n) 20000revs/min for respirable sizes.
