You can use the diferent types of innovation (product, process, organizational or marketing) and for creativity you can use intellectual property rights (trademarks, copyright, patents...).
I'm not convinced creativity and innovation can be extrapolated to a single measurement. Creativity is such a complex and multifaceted process. As Cravalho points out, you can measure *outcomes*, but is this the result of creativity across the company or of a group of creatives amid non-creatives. I suggest some reading of Kaufmann's work might help you define precisely what you mean by creativity.
Thank you colleagues for your answers. I agree with you. I would separately examine innovation and creativity in the company. He observed this as two variables. I just need a dimension with which to measure it. Nino and Zornitsa thanks to these dimensions. What other dimensions to use in his research to measure these variables?
Measuring innovation is indeed a very difficult task to perform. Yet, there are some ways that people used to apply.
(i) Innovation Sales Rate: new products sales percentage can be one dimension.
(ii) Number of idea received from employees. American company gets 100 times less written ideas than the Japanese company (James Surowiecki, 2008 in the New Yorker).

With some energy and persistence, it is not difficult to observe and to measure innovations at firms' level. You can use a multi-dimensional measure of the area(s) and the degree of novelty of an innovation (see enclosed). Creativity is deviation from the existing practices, patterns and beliefs. Not always it leads to a successful innovation. You should measure separately the degree of deviation from the common practices, industry's patterns and the common beliefs. For the common beliefs, you can use de Wit. B., Meyer R. "Strategy Synthesis" (various editions) as a starting point.
In order to measure innovation and creativity in organization, most of scholars using survey. Several established measurement scales are available in the current literature
