基于区域投入产出结构的财政乘数异质性
-
Infrastructure spending generates higher multipliers in regions with dense supplier networks and localized procurement mandates.
-
Input-output linkages determine whether stimulus flows primarily to wages, imports, or retained corporate profits.
-
Regions dominated by branch plants exhibit lower domestic value-added leakage than those with integrated manufacturing ecosystems.
-
Local content requirements boost backward linkage effects but may reduce allocative efficiency in competitive bidding.
-
Multiplier estimates derived from national models systematically misrepresent outcomes in export-oriented special economic zones.
-
Labor market tightness interacts with sectoral input dependencies to amplify or dampen initial spending impacts.
-
Fiscal transfers to fiscally distressed areas yield diminishing returns when local fiscal capacity constrains implementation speed.
-
Interregional trade coefficients reveal how construction spending in one province stimulates manufacturing output in another.
-
Digital platform intermediation fragments traditional input chains, weakening multiplier propagation in services-heavy economies.
-
Energy-intensive sectors distort regional multipliers when electricity pricing is administratively controlled rather than market-determined.
-
Supply chain fragmentation increases vulnerability to import substitution policies, altering baseline multiplier assumptions.
-
Policy evaluation must account for spatial autocorrelation in input-output tables, not just temporal lags.
