\begin{abstract}
It is challenging for a single development subject to complete complex
scientific research tasks due to the peculiarities of saline-alkali
land. Collaborative innovation and cooperation between development
subjects are increasingly vital. This paper first constructs an
undirected weighted collaborative innovation network from the upstream,
midstream, and downstream levels of technological innovation for
saline-alkali land development, analyzing the network's structural
characteristics and spatial distribution features. Then uses ERGM to
explore the internal and external driving mechanism for network
formation from network self-organization, subject characteristics, and
exogenous environmental factors. The results demonstrate that the
distribution of collaborative innovation networks for saline-alkali land
development is relatively uniform. However, there are also clusters, and
the clusters are mostly centered on universities and scientific research
institutions. Both the development subjects and clusters present
regional features. Centrality and transitivity are crucial in the
internal driving mechanism. In the external driving mechanism, the
Matthew effect is modest, and the Homozygous effect is considerable;
Organizational and technical proximity play a positive role;
Geographical and institutional proximity play a blocking role. This
study also provides practical enlightenment for encouraging horizontal
and vertical collaborative innovation of sustainable development of
saline-alkali land.%
