(4) Coordinating Management Agencies and Benefit Distribution Mechanisms
To ensure the efficient and stable operation of inter-regional collaborative response
mechanisms, it is crucial to establish robust coordinated management institutions. These
institutions are responsible for formulating overall plans and objectives for regional col-
laborative responses, clarifying the responsibilities and divisions of labor among regions
in coordinated efforts. By comprehensively considering factors such as regional resource
endowments, economic development levels, and technological capabilities, they develop sci-
entific and rational collaborative action plans to ensure orderly implementation of coordinat-
ed response measures. Simultaneously, establishing a fair and equitable benefit distribution
mechanism serves as vital support for maintaining inter-regional cooperation. Throughout
processes like resource allocation, technical collaboration, and experience sharing, full con-
sideration must be given to each region’s investments and contributions to ensure all partic-
ipants receive corresponding returns. For instance, in water resource allocation, regions pro-
viding water resources should receive reasonable economic compensation or other forms of
benefit returns; in technical cooperation, clear pricing for technology transfers and equitable
rights distribution should be established to protect the legitimate interests of technology-ex-
porting regions. Through such equitable benefit distribution mechanisms, we can prevent
cooperation obstacles caused by benefit imbalances, promote long-term stable collaboration
between regions, comprehensively enhance regional clusters’ climate change response capa-
bilities, and jointly address the severe challenges posed by climate change.

of Climate Change Impacts

I. Identification and Quantification Methods for Long-term Cumulative
Effects of Climate Change

In the vast field of climate change research, the precise identification and quantification
of long-term cumulative effects of climate change have become crucial keys to unlocking the
complex evolutionary mechanisms of Earth’s ecosystems, human societies, and the global
environment. This exploratory process holds immense significance, not only enabling us to
trace the profound impacts of past climate changes on Earth’s various spheres, but also pro-
viding solid theoretical foundations and data support for predicting future climate trends and
formulating effective response strategies through scientific quantification. To achieve this
grand objective, the scientific community has developed a series of effective methodologies,
among which time series analysis and cumulative sum models play vital and indispensable
roles in tracking the gradual accumulation of climate change impacts.
