Bayer has secured the top slot among pharmaceutical sector corporate reputations for the fourth straight year, according to the Reputation Institute's annual ranking, but the sector as a whole lags behind other industries.

Notably, in the Institute's ranking of top corporations across all sectors released last month, Bayer came in at No. 80.

Roche, Abbott and Lilly round out the top tier of the measurement of the top 12 global pharma companies in 15 markets. But those companies landed at 85, 89 and 92 among all sectors.

The Institute (full report - PDF) sees reputation formed by seven factors: performance, leadership, citizenship, governance, workplace, innovation and products/services. But it reports that from 48% to 58% of the public is unsure about what pharmaceutical companies are doing in those areas.

Globally, the pharma sector scored its highest reputation points in the US, Russia and Australia, while its lowest marks came out of Asia in South Korea, China (60, 4), Japan, and India.
