In this CSR, as rightly said by @rajagopal.s it is appropriate to say that CSR should be for some socio-economic development[this is the basic intepretation which is deemed to be displayed in Schedule VII of the Companies Act, 2013]. However, as the fund setup by State Governments is not taken under the perview of the CSR as per the Companies Act, 2013. The CSR cannot be funded under the scheme of the State government.
Further, if you are a company which is not actually wanting to spend on developing the society as the business is still on a small scale, then payment under Prime Minister relief fund is much appropriate from social and business point of view. As it help in showing the CSR expenditure under the Companies Act, 2013 and also the benefit of exemption can be obtained under the Income Tax Act, 1961.
So the question which comes is how the social development will come? in that case, understanding the policy of "ease of doing business" it is a better scheme for companies to focus on business and let the government get funded for the development of the funds.
