You can do a t-test to check if the mean response to that particular question is the same. 

Need more information on the research objectives and research questions. Also on the basic difference among the two groups and the heterogeneity criteria among the groups viz. was the approach in which the questions were asked different or the exposure to these products, etc. 

Thanks Rajdeep, 

                             Three constructs: 1. Good quality, 2. Cheaper price , and 3. sustainable production of product. asked from consumers

At the same time these related questions asked from manufacturing firm also. 

Conditions: 1. sample size for consumers is 150.

                    2. sample size of marketing managers or else senior level employee (30). 

Question: How to analyze the correlation between two different types of sample for the same products and analyze the result in term of fulfilling the expectation of consumers in term of green product features expectation of consumers and expectation fulfilment from company side. 

You can't analyse correlation without one to one correspondence, eg. Height of the man and his weight.

In your case, you can decide if there is a difference on the mean response between the two groups, if it is a Likert scale, using ANOVA  or t-test. If it isn't a Likert scale, then you will have to go for proportionality test or chi-square test. 

Please read the test axioms to see if they fit the criteria.
