4.3.2 Closeness Centrality and Innovation Performance
The regressive results of H6b indicate that closeness centrality of four kinds of
network have significantly positive effect on innovation performance. Hence, it
means that firms could reach other actors in shorter time and they get more
information and knowledge faster. Therefore they can enhance innovation
performance. Moreover, closeness centrality of LCD-InsNet has better explanation
on innovation performance.
4.3.3 Betweenness Centrality and Innovation Performance
The regressive results of H6c indicate that betweenness centrality of four kinds of
network have significantly positive effect on innovation performance. Hence, a firm
controls more information flow, it could gather more important information. Then,
the firm could perform better than others in innovation performance. Also,
betweenness centrality of LCD-InsNet has better explanation on innovation
performance.
4.3.4 Coreness and Innovation Performance
The regressive results of H6d indicate that coreness of four kinds of network have
significantly positive effect on innovation performance. Hence, firms in core have
better innovation performance than firms in periphery. Moreover, coreness of
LCD-InsNet has better explanation on innovation performance.
4.3.5 Structural Holes and Innovation Performance
The regressive results of H6e indicate that structural holes of only three kinds of
network have significantly positive effect on innovation performance. Hence, more
structural holes in actor's network will increase actor's access to diverse
information and, thus, have better innovation performance. Moreover, structural
holes of OptoNet have better explanation on innovation performance.

4.4 Position Variables in Explaining Innovation Performance
From the empirical results, we can find that almost every network position variable
had significantly positive effect on innovation performance, in spite of each
position variables' adjusted R square on innovation performance are different,
