Based on the investigation of entrepreneurs and government officials in an administrative region in central China，this paper analyzes the business environment and the political and business relationship of technology enterprises. The article describes the influence of the organizational size，organizational structure and the institutionalization and safety of the business environment on the closeness and transparency of political and business relationship. It is found that，overall，the relationship between politics and business is tending to be stable and transparent，showing the characteristics of “complementary symbiosis”. However，in practice，the grassroots political and business relationship also presents some characteristics that are not conducive to the construction of a close and incorrupt type of political and business relationship. These characteristics including：（1）the phenomenon of “neglecting business” and “lazy government” is still relatively obvious within a certain scope；（2）the government attention allocation mechanism leads to the Pattern of Difference Sequence in political and business contacts；（3）the lack of effective platforms to serve enterprises lead to the still existing political and business estrangement；（4）there is a certain degree of information asymmetry and a time lag for information acquisition in the communicationbetweenenterprises and government deposit；（5）The difference in corporate influence leads to the differentiation of political and business relationships among different enterprises. The article concludes with a discussion of the reasons and makes some suggestions.
