WASHINGTON, Dec 23 (Reuters) - New orders for U.S.-made capital goods unexpectedly fell in November while shipments rose modestly, suggesting that shortages were hampering business spending on equipment. Orders for non-defense capital goods excluding aircraft, a closely watched proxy for business spending plans, dipped 0.1% last month, the Commerce Department said on Thursday. These so-called core capital goods orders shot up 0.9% in October. Economists polled by Reuters had forecast core capital goods orders rising 0.6%. Shipments of core capital goods gained 0.3% last month after increasing 0.4% in October. Core capital goods shipments are used to calculate equipment spending in the GDP measurement. Business spending on equipment contracted in the third quarter after four straight quarters of double-digit growth. It was weighed down by a shortage of motor vehicles. A global shortage of semiconductors is hampering motor vehicle production. Orders for durable goods, items ranging from toasters to aircraft that are meant to last three years or more, accelerated 2.5% last month after edging up 0.1% in October. They were boosted by a 6.5% jump in orders for transportation equipment, which followed a 0.3% drop in October. Motor vehicle orders increased 1.0% after rebounding 5.8% in October. Orders for the volatile civilian aircraft category soared 34.1% after falling 4.1% in October. Boeing (BA.N) reported on its website that it had received 109 aircraft orders last month compared to only 10 in October.
