How to innovate leisure agriculture in the new period is the core issue in the high-quality development of leisure agriculture. The research holds that whether it is the macro “trend of leisure agriculture system supply”, the middle “characteristics of leisure agriculture industry itself” and the micro “characteristics of leisure agriculture enterprises”, it is the rational choice to choose non-technical innovation for the high-quality development of leisure agriculture in the new period. With the acceleration of technological innovation, the importance of non-technical innovation has become increasingly prominent. The organization for economic cooperation and development (OECD) and the European Statistical Office (Eurostat) have not only expanded the definition of innovation, but also increased marketing innovation and organizational innovation. These two kinds of innovations are not technological innovations in themselves, but they are of great significance to the growth of productivity and economic development. Taking Jiangsu as the research area, it took two years (2020–2021) to conduct a field survey on 31 representative leisure agricultural enterprises in seven cities of southern, central and northern Jiangsu. The results showed that non-technological innovation factors were the key to these representative enterprises' competitive advantage, but it was also found that Jiangsu leisure agricultural enterprises needed systematic support from non-technological innovation to “excellence”. Based on industrial economics, technological innovation economics and evolutionary economics, this paper tries to build a non-technological innovation system of leisure agriculture in Jiangsu province, and puts forward some countermeasures and suggestions for the high-quality development of leisure agriculture under the system construction from two dimensions of government and enterprises.
