The four fiscal accounts (general public budget / government fund budget / state-capital operations budget / social insurance fund budget) constitute the complete foundational structure of government funding; built upon this, the broad fiscal aggregate layers onto the narrow annual budget the fund-based expenditures, local special-purpose bonds, policy-bank bonds, urban-investment bonds (城投债), and PPP — this is the correct definition for estimating the true funding pool behind infrastructure investment. Following the three steps of “broad fiscal aggregate (space) → expenditure progress (pace) → infrastructure growth (outcome),” the annual trajectory of infrastructure can be systematically estimated.
The Framework As It Stands

Why Infrastructure Estimation Must Begin with Fiscal Analysis
Infrastructure investment is initiated by government entities (central projects + local projects) and has direct or indirect ties to fiscal policy; before analyzing infrastructure, one must first understand the complete composition of the fiscal sector. Fiscal analysis starts from two layers: the four fiscal accounts (foundational structure) and the broad fiscal aggregate (true funding pool).
The Four Fiscal Accounts
The First Account — General Public Budget: Revenue consists of government fiscal and tax income (taxes + fees); expenditure covers all segments including infrastructure, pensions, health, and education, with a detailed annual budget system.
The Second Account — Government Fund Budget: The core revenue item is land-transfer proceeds; local government finance is in a meaningful sense “land finance,” with land-transfer receipts serving as a stable government revenue source usable for expenditure across departments.
The Third Account — State-Capital Operations Budget: State-owned enterprise revenues and profits are linked to the government; SOE profits constitute a key component of the macro-fiscal system (the distinctive role of SOEs within China’s fiscal structure).
The Fourth Account — Social Insurance Fund Budget: Social security revenue and expenditure are subject to budget constraints; following entry into aging, social security pressure rises (at the course reference point of 2019-01, social insurance fund revenue and expenditure growth exceeded 30%), becoming a necessary consideration for fiscal balance.
Narrow Fiscal vs. Broad Fiscal
Narrow fiscal = annual government budget fiscal (centered on the general public budget).
Broad fiscal = narrow fiscal + fund-based expenditures + local special-purpose bonds + policy-bank bonds + urban-investment bonds (城投债) + PPP.
Example (data current at the course reference point, 2019-01): local special-purpose bonds RMB 1.35 trillion, essentially unused in the first half of the year, becoming a significant broad-fiscal expenditure item in the second half.
The Three-Step Infrastructure Growth Estimation Method
① Frame the total broad fiscal aggregate and its growth rate (space)
↓
② Track monthly fiscal expenditure progress (pace) — as a share of the full-year broad fiscal aggregate
↓
③ Use this to estimate the year's infrastructure trajectory (outcome)
This framework is validated by the historical relationship between expenditure progress and infrastructure trajectory in 2017: expenditure progress and infrastructure growth were highly co-moving, confirming the validity of the three-step path.
The Three Primary Economic Drivers and Infrastructure’s Weight
This framework is based on an input-output table estimation; China’s three primary economic drivers are exports, real estate, and infrastructure (a significant share of consumption is derived from the three):
| Driver | Estimated share of industry-chain-scope impact (course estimate) (course framing, 2019-01) |
|---|---|
| Exports | approximately one-third |
| Real estate | approximately one-third |
| Infrastructure | approximately one-tenth |
Definition caveat: The table above uses an industry-chain-scope definition, not the narrow expenditure-method definition. Under the expenditure method, net exports account for only approximately 2% of GDP, but exports’ real role is to drive capital formation through upstream and downstream industry chains; using the expenditure-method definition systematically understates the true impact of exports and real estate.
Time-point caveat: The above figures — special-purpose bonds RMB 1.35 trillion, the 2017 validation case, the three-driver shares, net exports’ GDP share of approximately 2%, and social insurance fund growth exceeding 30% — all reflect historical experience or contemporaneous estimates as of the course date (2019-01). Judging current infrastructure growth, fiscal space, or three-driver shares requires using current-period broad fiscal quota, special-purpose bond issuance volumes, and the latest expenditure progress data.

The Soul-Anchor Layer
The proprietary increment in this entry lies in the critical-point of switching definitions. Reading only the annual budget deficit (the revenue-expenditure gap in the general public budget) yields one number; adding the government fund expenditures (the land-transfer-proceeds side) already changes it; layering on the RMB 1.35 trillion in local special-purpose bonds (2019-01 year) deployed en masse in the second half, the scale of the funding pool is in an entirely different order of magnitude. The specific error of the old mental model is: upon seeing “fiscal deficit of X trillion,” directly inferring infrastructure acceleration/deceleration without asking “how much ammunition remains under the broad definition” — missing special-purpose bonds, policy-bank bonds, and urban-investment bonds, which are the three most elastic components of broad fiscal, resulting in a systematically low forecast for infrastructure growth.
Consumption appears to be an independent driver, but furniture, appliances, home renovation, and automobiles — these major consumption categories are all derived variables of the real-estate chain; under the industry-chain definition, real estate is approximately one-third and exports approximately one-third, together already close to two-thirds; macroeconomic research should first locate these two and then layer infrastructure at approximately one-tenth — this is the correct order for perceiving driver weights. Using net-exports’ GDP share of approximately 2% under the expenditure method as a reference point for exports’ importance employs the wrong definition, leading to systematic underestimation of exports’ pull on manufacturing investment and employment.
The broad-money thinking in Total Social Financing and Broad Money M2: Accounting Definitions and Divergence and the broad-fiscal thinking in this entry are isomorphic: in both domains, “the narrow number is visible, but the broad number is the real one” — a cognitive switch is required. The Inflation Triangle Model: Two-Layer Forecasting and High-Frequency Tracking’s input-driven factors (oil prices → PPI → CPI) in the transmission chain are ultimately amplified or compressed through the broad fiscal scale on the demand side of infrastructure investment.
