本文主要在探討中國大陸「大中型企業」(large and medium-sized industrial enterprises)與「研發機構」(research institutions)兩種不同途徑的研發活動支出對於中國大陸製造業的生產力何者具最佳貢獻?本研究為了檢證研究問題,蒐集中國大陸26個製造業在1993-2005年之追蹤資料(panel data),對Battese and Coelli (1995)所提出之實證模型進行估計,來檢視不同途徑的研發投入與外溢效果對中國大陸總體製造業、輕工業及重工業生產效率的影響。實證估計結果顯示:(一)以「研發機構」研發投入估算的研發資本與跨產業研發外溢效果表現較「大中型企業」研發投入佳;(二)由「研究開發機構」的研發投入所估算出之研發資本與外溢效果對於中國大陸整體製造業、輕工業、與重工業生產力的貢獻,整體上皆優於「大中型工業企業」研發投入的貢獻。
This paper aims to analyze and compare the contributions from two different R&D inputs, the channels of ”large and medium-sized industrial enterprises” and the ”research institutions”, on the productivity of manufacturing industries in China. This study employs the panel data of 26 manufacturing industries in Mainland China from 1993 to 2005 and develops empirical models proposed by Battese and Coelli (1995) to estimate the stochastic frontier production function. The empirical results show that, First, the estimated innovative capital of ”research institutions” is higher than ”large and medium-sized industrial enterprises”. Secondly, the innovative input of ”research institutions” has better contributions than ”large and medium-sized industrial enterprises” on the productivity of whole, light, and heavy manufacturing industries.
