在阅读一篇文章的数据分析时，所得结果如附件所示。

文中这样写道“Table 2 shows the results of the analyses predicting the reputation effects of the various facets of a firm’s market actions. Hypothesis 1 argues
that a firm’s total market actions will positively affect its reputation. Model 1 demonstrates support for Hypothesis 1 at the p< 0.05 level. According to Hypothesis 2 the complexity in a
firm’s action repertoire has a positive effect on a firm’s reputation. The positive coefficient for the repertoire complexity variable is significant at the p< 0.05 level in Model 1 and provides
support for Hypothesis 2. Testing for the moderating effect of industry concentration on these variables in Model 2 and Model 3, we find that the interaction of total actions and industry concentration is not significant. Hypothesis 3a is therefore not supported. In contrast, the interaction effect between repertoire complexity and industry concentration is significant at the p< 0.05 level, supporting Hypothesis 3b.

求助各位大侠，这个结果为什么是这样分析的？
