Community and property exchange

Participate in the discussion. I think it's basically class C to express demand. What is needed is to express and solve problems, not anything else. The meaning of expressive demand is: "It is defined by whether people in need really seek services and whether they are satisfied." Here, "people in need" refers to community residents, and "services sought" refers to "property services". Whether the service meets the legal, reasonable and reasonable requirements of the owner, and then puts forward the requirements.

We can also judge the answer by the meaning of exclusion. For example, Class A normative requirements are defined by some existing standards or specifications, and usually come from conventions, authorities (experts, administrators) or general knowledge. Community residents can refer to such standards, only as a "theoretical" basis, not as a demand purpose.

Similarly, class B sensory needs are "defined by people in need, and people realize what kind of needs and the degree of needs they have through imagination and feeling." Obviously, community residents have gone beyond this stage, not just imagining and feeling, feeling, but as you said, "the theory of residents looking for property" has risen from a low level to a "theoretical" level.

Secondly, category D comparative demand refers to "comparing similar areas or people and evaluating the service gap between them." The introduction of the problem does not involve other property communities, and there is no other "comparison" reference.

I also believe that the four types of requirements should not be separated, it can be a different requirement acquisition process and a complementary combination tool. In other words, we can imagine that community residents have some unpleasant feelings, which will produce sensory needs (b), and then think of the relevant contents of the Property Law and property management regulations or property service agreements, and then produce normative needs (a). Just when they see that the property services in neighboring communities are doing well, they immediately think of comparative demand (D). Finally, they need to combine these needs to make the services of property companies unsatisfactory, inadequate and irregular.
