1. ··1931Foreign Trade Monopoly LawCorrelationExpected causation

   Majlis grants the government a monopoly over all foreign trade, empowering it to set import quotas tied to non-oil export proceeds and to establish state trading companies for sugar, tea, opium, tobacco and cereals -- the legal basis for an import-substitution industrialization strategy.

   Why this link: The state trading monopoly and import quotas created the protected domestic market that underpinned the roughly 265 new plants of the 1930s import-substitution industrialization drive.

   Caveat: No sectoral value-added data exists for the 1930s; the link is to the historical process, not the charted series itself.

2. 011934State-led industrialization drive acceleratesCorrelationExpected causation

   Backed by high protective tariffs and Bank Melli financing, state and private investment establish roughly 265 new plants (textiles, sugar refining, cement, matches, glass) between 1930 and 1940, with industrial growth peaking in 1934-38 under direct state direction.

   Why this link: This 1930-40 wave of roughly 265 new state- and privately-built plants (textiles, sugar, cement, matches, glass), financed by Bank Melli under high protective tariffs, is the founding episode of Iran's modern industrial sector that these value-added series describe.

   Caveat: No national accounts by sector exist for the 1930s; the link is to the historical process these categories describe, not measurable in the charted data itself.

   Lag: Decades to charted dataSource: Encyclopaedia Iranica (Industrialization i. The Reza Shah Period and Its Aftermath 1925-53)

Related_Laws

Laws related to this measure. Correlation = how closely this law tracks this measure's story. Expected causation = how strongly we would expect it to have moved the line. Neither is a claim of proof.

1. 1969CorrelationExpected causationAct on the Purchase of Agricultural Land for Industrial and Mining Needs

   Passed in 1969, this law lets state and private industrial and mining enterprises lease or purchase farmland, including tenant farmers' cultivation rights, needed for their projects, with the price set by negotiation or, failing agreement, by a government commission, and gives displaced farm workers priority for jobs at the new facility.

   Why this link: The land acquired under this law was earmarked for industrial and mining sites, giving it an indirect channel into industrial value added.

   Caveat: Industrial value added is driven overwhelmingly by capital investment, oil-financed development spending, and macro conditions, not land-acquisition mechanics.

2. 1984CorrelationExpected causationBylaw on Mineral Exploration and Discovery Award

   Adopted in 1984, this bylaw set up a licensing regime for mineral exploration and established a discovery bonus, calculated by the Supreme Mining Council based on the value of the ore reserve found and paid from the Mining Ministry's annual budget, to reward prospectors.

   Why this link: This 1984 bylaw set procedures and cash rewards for private discovery of mineral deposits, a supply-side incentive meant to expand mining exploration and, eventually, mineral output and rents.

   Caveat: A minor administrative bylaw among many mining-sector incentives; exploration rewards cannot be isolated from world commodity prices, state investment, and sanctions as drivers of Iran's mineral output and rents.

   Lag: Effects on exploration and output would emerge over years, not immediately.
3. 1988CorrelationExpected causationBylaw on Financial and Equipment Assistance to Holders of Industrial Research Licenses

   This bylaw provides financial and equipment assistance to holders of industrial research licenses.

   Why this link: This 1988 bylaw provides financial and equipment aid to holders of industrial research permits, an incentive instrument aimed at boosting industrial R&D and, through it, industrial-sector output and value added.

   Caveat: Industrial value added is driven overwhelmingly by oil-sector linkages, import substitution policy, and the war economy in this period; the effect of this narrow research-incentive bylaw cannot be separately measured.

   Lag: Multi-year lag as R&D investments mature into production gains.
4. 2000CorrelationExpected causationBylaw on the Method of Determining and Classifying Large and Small Mines

   Approved in 1379 AH (2000), this bylaw set mineral-reserve thresholds, for example over 150 million tons for iron ore, 5 million tons for chromite, or 100 tons for gold, above which a mine is classified as large rather than small, a classification the Ministry of Mines and Metals uses to determine which regulatory regime applies.

   Why this link: This 2000 bylaw sets the criteria distinguishing large from small mines, directly shaping licensing terms, royalty obligations, and investment incentives across Iran's mining sector.

   Caveat: Mining output is driven mainly by global commodity prices, domestic energy/input costs, and sanctions-era investment constraints; this classification bylaw is one structural input among many and predates our only modern mining-value chart by nearly two decades.

   Lag: Classification criteria shape licensing and investment decisions within the following years.
5. 2000CorrelationExpected causationInterpretive Act on Article 29 of the Mining Act (Approved 27/2/1377)

   Passed by parliament in Ordibehesht 1379 (2000), this interpretive act clarifies that Article 29 of the 1377 Mining Act repeals all laws, decrees, and directives requiring mineral extractors to pay amounts other than taxes and government royalties, while fees that do not affect production cost remain in force.

   Why this link: A 2000 interpretive law clarifying Article 29 of the Mining Law is part of the legal-regulatory scaffolding (licensing, royalty computation) underlying Iran's mining sector.

   Caveat: It is a narrow legal clarification of a single article, not a substantive policy change, and cannot be isolated as a driver of mining output value on the one modern chart we hold.

   Lag: Interpretive clarifications typically affect licensing practice within the same year.
6. 2001CorrelationExpected causationMining Engineering System Act

   This law establishes a regulatory system for the engineering profession in the mining sector.

   Why this link: This 2001 law established a professional licensing/engineering-system regime for mining engineers, a regulatory backbone for the sector rather than a direct production driver.

   Caveat: Purely a professional-regulation statute; mineral output volumes are driven by global commodity prices, investment, and geology, not by engineer licensing rules, so attribution to production series is minimal.

   Lag: Diffuse, no clear lag.
7. 2003CorrelationExpected causationAct on Facilitating Industrial Modernization and Amending Article 113 of the Third Development Plan Act

   Passed in 2003, this law aims to remove obstacles to industrial modernization by letting banks finance the bid and performance guarantees Iranian contractors need to compete for domestic and foreign industrial and construction projects, in order to boost local content and employment.

   Why this link: Enacted under the Third Development Plan (1382/2003), this omnibus law facilitates financing for industrial renovation and modernization, touching customs, banking, mining, and state-land transfer rules relevant to industrial firms.

   Caveat: An omnibus facilitation law with diffuse effects across many sectors; industrial value added is driven far more by sanctions, energy input costs, and exchange rates than by this specific financing-facilitation statute.

8. 2009CorrelationExpected causationBylaw on the Manner of Supplying Electricity and Fuel to Industries

   Approved in 2009 (1387), this bylaw requires the industries ministry, with the oil and power ministries, to give new-plant applicants outside industrial parks a standardized energy-supply guide, obliges the oil ministry to guarantee natural gas to gas-fed plants, requires equal fuel and subsidy treatment for state and private power plants, and lets industrial consumers connect to the grid either by building a captive power plant or by signing bilateral power-purchase contracts with private generators.

   Why this link: This 2009 bylaw set the arrangements for supplying electricity and fuel to industrial plants, a real operational channel affecting industrial output and the reliability of the energy access that underpins the manufacturing sector.

   Caveat: Industrial value-added and electricity-access aggregates reflect investment, sanctions, and broader energy-supply conditions far more than a single administrative bylaw on supply arrangements; its specific effect cannot be isolated.

9. 2009CorrelationExpected causationExecutive Bylaw on the Classification of Enterprises, Certification of Financial Statements, and Marketing of Enterprises Subject to Divestiture

   Sets the procedure for privatizing state-owned enterprises: classifying them by financial and operational criteria, requiring certified audits of their financial statements before sale, and defining how they are marketed and offered to buyers under the state privatization program.

   Why this link: Governs the restructuring and sale of state-owned industrial and mining enterprises, affecting sectoral value-added composition.

   Caveat: Sectoral value added is dominated by energy prices, sanctions, and input costs; the effect of enterprise valuation/marketing rules alone is not separable.

10. 2013CorrelationExpected causationAmendment to the Executive Bylaw of the Mining Act

    This decree amends the executive bylaw implementing the Mining Act.

    Why this link: This 2013 amendment to the Mining Law's implementing bylaw updates the licensing/regulatory framework that governs mining activity, temporally close to our provincial mining-value chart (2018-2023).

    Caveat: Mining production value is dominated by global commodity prices and sanctions-driven export constraints; this bylaw amendment is a regulatory input, not a demonstrated driver of the output series.

    Lag: Bylaw amendments affect licensing/operating practice within 1-2 years.
11. 2015CorrelationExpected causationExecutive Bylaw of Article 44 of the Act on Removing Obstacles to Competitive Production and Improving the Country's Financial System

    Approved in 2015, this bylaw allows the government to co-invest, up to a maximum 49% share, in non-governmental research and technology funds that finance applied research and technology development by the private sector.

    Why this link: Privatized enterprises under Article 44 span manufacturing, mining, and industrial sectors, so the program bears on sectoral value-added trends.

    Caveat: Sectoral value added is shaped by many structural and cyclical factors; the specific contribution of privatization transfers cannot be isolated.

    Lag: Multi-year.
12. 2015CorrelationExpected causationExecutive Bylaw of Note 2 of Article 3 of the Act Amending the Mining Act

    This bylaw implements note 2 of article 3 of the act amending Iran's Mining Act.

    Why this link: This 2015 bylaw implements a note to Article 3 of the amended Mining Law, governing licensing/exploitation terms for mines, a real regulatory channel shaping the value of mine production captured in the provincial mining-value series (2018-2023).

    Caveat: Mine production value by province also reflects commodity prices, sanctions on metal exports, and provincial infrastructure investment, so the bylaw's specific contribution cannot be isolated from these larger drivers.

    Lag: Multi-year; licensing changes affect exploitation decisions with a delay of several years.
13. 2017CorrelationExpected causationAddition of a Note to Article 118 of the Executive Bylaw of the Mining Act

    This decree adds a note to article 118 of the Executive Bylaw implementing the Mining Act.

    Why this link: Adds a note to Article 118 of the Mining Law's executive bylaw in 2017, part of the regulatory framework for the mining sector whose output value by province is tracked from 2018 onward.

    Caveat: A single administrative note to one article cannot be credited with movements in provincial mining output value, which is driven mainly by commodity prices and investment cycles.

    Lag: Immediate administrative effect; no measurable lag on output value.
14. 2025CorrelationExpected causationExecutive Bylaw of Sub-item (7) of Clause (d) of Article (48) of the Seventh Five-Year Development Plan Act of the Islamic Republic of Iran (Subject: Allocation of Presold Petrochemical Company Products, for Which There Is No Export Commitment, to Downstream Complexes or Units along the Value Chain)

    This executive bylaw implements a provision of the Seventh Five-Year Development Plan Act allocating presold petrochemical products with no export commitment to downstream complexes or units along the value chain.

    Why this link: Implements clause 7(d)(4) directing petrochemical output that goes unexported and pre-sold to be allocated to downstream domestic units along the value chain, an industrial feedstock-supply instrument for petrochemical derivatives manufacturing.

    Caveat: A 2025 implementing bylaw too recent to show measurable effects in available series; it channels output rather than creating it, so its contribution to industrial value added is real but hard to isolate from broader petrochemical capacity trends.

    Lag: Too recent (2025) for lagged effects to appear in current data.
