Import Technology Spillover, Correlation Effect and its Influence on Improving China Industrial Productivity: an Analysis Based on Structural Decomposition

Based on trans-national and trans-industrial panel data collected from OECD-STAN, UNCOMTRADE and China Statistical Yearbooks, and by full consideration of knowledge heterogeneity from both country and industry aspects, also considering industrial correlation effect between manufacturing and service, the study mainly focuses on import technology spillover and its diversified decomposition characteristics, and its influence on improving industrial productivity. Main findings show: (1) In consideration of the intra-industrial and inter-industrial correlation effect, technology spillover of import has showed an apparent influence on improving industrial productivity, enhanced correlation effect here played an important catalytic role. (2) Under influence of the correlation effect, and compared with the intra-industrial correlation effect, the inter-industrial correlation effect has played a more prominent role in promoting productivity in both manufacturing and service.(3) Through correlation of reverse requirement and forward input, technology spillover in manufacturing or service each has shown more influence in improving productivity on the other. Finally, from aspects of strengthening industrial correlation, especially industrial correlation between manufacturing and service, and accumulation of human capital, it provides some essential suggestion.
