Table 12: Decomposition results of the spatial effect of agricultural technology R&D on agricultural green development under the economic matrix. The indirect effect reflects the cumulative spatial spillover effect of all regions in the sample, and its size reflects the spillover degree of changes in explanatory variables to neighboring provinces. It can be seen from Tables 12 and 13 that the spatial spillover effects of agricultural technology R&D and agricultural technology application are 0.0213 and 0.0314, respectively, and both passed the 10% significance level test, indicating that the improvement in the agricultural science and technology innovation level in this province will promote agricultural green development in neighboring provinces through a positive spillover effect. The reason is that, on the one hand, the policy measures and strategic behaviors adopted by neighboring provinces in the agricultural science and technology investment and innovation support system for economic development cause them to imitate, learn from and compete with each other. Specifically, the investment of R&D funds, the investment of technical personnel and the construction of agricultural research institutes will spread to neighboring provinces through demonstration effects. On the other hand, with the continuous strengthening of regional economic integration, the regional links become closer, which is conducive to the construction of the upstream-midstream-downstream agricultural industrial chain combining regional specialization and division of labor cooperation, and then promote the sharing of agricultural science and technology innovation resources and knowledge between provinces. The results show that there is a positive correlation between agricultural technology innovation and agricultural green development in neighboring provinces, namely, the spatial spillover effect. For example, the Northeast Regional Agricultural Science and Technology Innovation Alliance was established in 2017, which is aimed at integrating agricultural science and technology innovation resources in northeast China and promoting sustainable agricultural development in northeast China through collaborative innovation among different regions. On the whole, the spatial spillover effect of agricultural technology application is 2.6 times the direct effect, accounting for about 72.35% of the total effect, which indicates that from the spatial perspective, multilateral coordination and strengthening of agricultural technology application between the province and neighboring provinces will greatly promote the development level of green agriculture in the province. The key factor is the spatial spillover effect from the application of agricultural technology in neighboring provinces. In addition, when agricultural technology research and development is the core explanatory variable, the spatial spillover effect of financial support to agriculture is \(-0.0039\), which fails the significance test, indicating that with agricultural technology research and development, financial support for agriculture has not formed a significant inhibitory effect on neighboring provinces. When the application of agricultural technology is taken as the core explanatory variable, the spatial spillover effect of financial support for agriculture is \(-0.0326\), which is \(-118\%\) of its direct effect.
