com·ple·men·tar·i·ty

(kom'plĕ-men-tār'i-tē),
1. The degree of base-pairing (A opposite U or T, G opposite C) between two sequences of DNA and/or RNA molecules.
2. The degree of affinity, or fit, between antigen- and antibody-combining sites.
3. The degree of affinity, or fit, between an enzyme and a substrate.

1. The degree of base-pairing between two sequences of DNA and/or RNA molecules.
2. The degree of affinity, or fit, of antigen and antibody combining sites.

complementarity (kamˑ·pl·men·tarˑ··tē),

n a concept in quantum physics, proposed by Neils Bohr, in which total information about a subject or system cannot be obtained because the information is located in at least two complementary qualities. Measuring one quality precludes measurement of the other.

complementarity

the relationship between bases in the DNA double helix whereby every base on one strand is matched to a complementary hydrogen bonding base on the other strand.

complementarity-determining region (CDR)
restricted regions within the variable regions of antibodies that bind to antigenic determinants.

This suggests that these two combinations are beneficial for firms, and the reason might lie in the complementarities between internal R&D and cooperative R&D, and between external R&D and cooperative R&D.
Our empirical strategy follows the line of Schmiedeberg (2008), which also uses the adoption approach and productivity approach separately to test the complementarities between three R&D strategies.
jk] represents the effects of complementarities between R&D strategies on innovation activities; and [Z.
In addition, according to the coefficients of rd12, rd13 and rd23, the significantly positive results support the existence of complementarities between the three R&D strategies pair-wisely meaning that simultaneously engaging in multiple R&D strategies facilitates innovation output on the part of firms.
The significantly positive coefficient for rd23 suggests that R&D complementarity only exists between external R&D (rd2) and cooperative R&D (rd3), which contradicts what we have obtained in Table 3, where complementarities between pair-wise R&D strategies are all significant given that the innovation output is estimated by the sales ratio from new products.
We also see that the complementarities between R&D strategies are supported by estimating the results in both models with and without selection equations.
A good understanding of complementarities is not only helpful for firms' R&D decisions but also crucial for government industry policies.
Besides, we empirically test the pair-wise R&D complementarities among three R&D strategies, namely, internal R&D, external R&D and cooperative R&D.
Our empirical results strongly support the existence of R&D complementarities among three types of R&D strategies - internal, external and cooperative R&D strategies, when innovation outputs are measured by sales share of new products and marginal return to R&D investment.
To sum up, using a manufacturing firm-level data set from the newly-industrialized country--Taiwan, generally we are able to establish the complementarities between three alternative R&D strategies.

Currently, work in the complementarities group falls into three broad areas.
