New Delhi, Sep 6 - India Inc.'s confidence is up, though high interest rates and rising costs of raw materials and manpower have marred its capacity to do better, a survey released here Sunday said.

According to the Federation of Indian Chambers of Commerce and Industry (FICCI), corporate India's confidence in the state of the economy, industry and firm-level performance is on the upswing.

'While availability of credit is not a problem, the corporate sector's capacity to do better is being marred by the rising cost of raw materials and manpower and high rates of interest,' said FICCI's Business Confidence Survey (BCS) for the first quarter of 2009-10.

The survey said there is a general consensus among members of corporate India that the fiscal stimulus measures has an impact on economic activities.

About 80 percent of the companies subscribe to that view - and that going ahead India would see an improvement in its growth performance.

The survey drew responses from 372 companies with a wide geographical and sectoral spread.
