Technological Improvement Depends On

R&D Expenditure

This neglects EXTERNAL sourcing!

Measurement of External Sourcing:Technology Balance of Payment (TBP)

TBP payments capture the firm’s activities of importing the disembodied technology, while TBP receipts enable us to measure the exportation of disembodied technology through export

Reference: TBP Manual (1990); Hollanders (2008)

6

Reasonably Using TBP Data

However, TBP data has its limitations, and sometimes can be misused.Ex: Some policy makers tend to merely consider surplus or deficit of technological trade when proposing new policies

7

Our Research Purpose•Prop

osing a reasonably framework for policy makers to utilizing TBP data

I

•Conducting an innovation efficiency measurement encompassing both internal and external indicators

Data Envelopment Analysis (DEA)

DEA is a widely acknowledged linear programming model for calculating efficiency, even in cross-country studies.Ex: Rousseau and Rousseau (1997)Wang and Huang (2007)Sharma and Thomas (2008)

Reference: Charnes et al.(1994); Farrel(1957); Banker et al.(1984)

Concluding Remarks

•TBP is a both practical and convenient indicator, on condition that we analyze and interpret it properly

I

•Both internal and external indicators should be taken into consideration when analyzing national innovation efficiency
