Technology market prosperity and regional economic development are inseparable and the gap between different regional technical trading markets has become an important factor affecting regional coordinated development. The empirical analysis of Chongqing technical products flow direction based on Market Share Model shows that in regional technical market pattern, the impact of market scale and economic development level in technology-imported areas on technical flow scale and technical market trading pattern is relatively significant and that the influence of demand change in technology-exported areas on total trading pattern is not obvious, however, the effect of demand change in relatively developed areas on total technical trading pattern is relatively remarkable. Based on this, the optimization of regional technical trading pattern in less-developed areas should be based on demand market feature of relatively developed areas and local technical trading reality, use the two strategies of ‘market-developing’ and ‘cultivation of internal technology and import of external technology’, studiously push forward policy innovation, gradually optimize regional technical trading pattern and upgrade regional core competence.
