The rapid development of the new generation of digital technology has injected new vitality into the digital transformation (DT) and continued growth of enterprises. This paper selects data from China's A-share listed companies from 2010 to 2019 and uses transaction cost theory to empirically test the effect of enterprise digital transformation (EDT) on enterprise growth and its mechanism. Research has found that DT can significantly promote enterprise growth. The reduction of supply chain collaboration costs plays an important role as an intermediary mechanism in this process. At the same time, industry competition intensity, regional marketization level, and digital infrastructure level have played positive regulatory roles. In addition, when the enterprise's level of financing constraints is low and it is a manufacturing enterprise or state-owned enterprise, the promotion effect of EDT on enterprise growth is more significant. While expanding the research perspective and measurement methods of EDT, this paper integrates the strategic actions of EDT and the inter-enterprise collaboration costs of the supply chain into a unified theoretical framework, revealing a new theoretical mechanism for DT to promote enterprise growth. It also provides practical inspiration for relevant policy formulation and enterprise transformation and upgrading.

ABSTRACT Clay soil results in higher crop yield and quality than sandy soil. However, irrigation causes clay soil to slump easily, increasing compactness and decreasing soil oxygen content. This study investigated the effects of dry seeding and wet emergence on the soil microenvironment and cotton growth promotion in Xinjiang silt loam fields. The experimental design included three aerated and three non-aerated treatments. The results showed that aerated irrigation decreased dry density of the 0–20 cm soil layer to different degrees, the field capacity increased to different degrees, and the dry density and field capacity of the 20-30 cm soil layer did not change among the different treatments. The dry density and field capacity of WP2 treatment changed the most, the dry density of 0-10 cm and 10-20 cm soil layer were respectively 1.28 g cm-3 and 1.27 g cm-3, and the field capacity were respectively 35.23% and 35.7%. Under the same irrigation quota, the soil water content of the aerated treatments was lower than that of the non-aerated treatments. Aerated irrigation inhibited the horizontal diffusion of water and facilitated downward water transport. The WP2 treatment had the highest peak soil temperature at depths of 10 and 20 cm, and the WP2 treatment had the highest numbers of bacteria, fungi, actinomycetes, urease, and catalase activities, seedling emergence, primary root length, plant height, and stem thickness.
