Did Liang Zhongtang's Yicheng two-child pilot begin in 1980 or 1985, and do Yan Wei & Li Zhang's 2014 re-examination name Liang as its architect?

This capture targets question-verify-yicheng-pilot-start-date-yan-wei-li-zhang-2014. It resolves the date half of the question with new, independent Tier-1 corroboration. It does not resolve the authorship half: Yan Wei & Li Zhang's 2014 The China Journal article, "Re-examination of the Yicheng Two-Child Program" (China Journal 72: 98–120), remains paywalled and unread after this session's search — the same gap the question already named. That specific sub-question stays [unverified -- could not confirm or deny after search].

Claim: A peer-reviewed demography journal independently dates the Yicheng pilot's start to 1985, not 1980, corroborating Liang's own account over Whyte-Wang-Cai's citation

Yu Qin & Fei Wang's "Too early or too late: What have we learned from the 30-year two-child policy experiment in Yicheng, China?" (Demographic Research 37, article 30, pp. 929–956, October 2017) states in its abstract: "We reviewed the 30-year (1985–2015) two-child policy experiment carried out in Yicheng, a county in the Shanxi province of China." The paper's conclusion restates this directly: "In this paper, we studied the two-child policy experiment implemented in Yicheng beginning in 1985." Elsewhere it describes Yicheng as "the only jurisdiction with a persistent two-child policy since 1985."

This is a quantitative/historical-date claim resting on a peer-reviewed, named-author article in an established open-access demography journal — clears the Tier 1-2 sourcing floor for dates with room to spare. It is independent of both existing vault accounts: it does not cite Liang's own retelling (the Sixth Tone source behind claim-liang-zhongtang-1979-two-child-proposal-and-1985-yicheng-pilot) for the date, and it is not the Whyte-Wang-Cai essay that attributed "since 1980" to Yan Wei & Li Zhang's 2014 re-examination (recorded in claim-whyte-wang-cai-and-liang-disagree-on-yicheng-pilot-start-date). Qin & Wang do cite Wei and Zhang (2014) in their reference list — for the specific terms of the policy's marriage-age and birth-spacing rules, not for the start date itself, which Qin & Wang state independently and repeatedly throughout their own paper (abstract, introduction, Section 2 "Policy background," and conclusion).

This narrows, without fully closing, the five-year conflict the question names: a second, independent, Tier-1 source now sits on the 1985 side of the discrepancy, against the one Tier-1 source (Whyte, Wang & Cai, reporting Yan Wei & Li Zhang's finding at second hand) that sits on the 1980 side. The underlying Yan Wei & Li Zhang 2014 article itself — the one document that could settle whether "1980" or "1985" is its own stated figure, as opposed to Whyte-Wang-Cai's gloss on it — remains unread.

Claim: The same peer-reviewed source independently names Liang Zhongtang as the pilot's proposer and the person whose advocacy secured provincial approval

Qin & Wang (2017) write: "In the spring of 1984, Liang Zhongtang, a demographer in the Shanxi province People's Government Economic Research Center, proposed a restricted two-child policy that would require couples to marry later and wait longer before having a second child. In 1985, Liang's advocacy for this policy convinced the provincial government to allow Yicheng, a county in Linfen prefecture city, to replace the OCP with the two-child policy proposed by the demographer."

This is a historical/biographical claim (who did what, when) that is contested within this vault's existing cluster — claim-whyte-wang-cai-cite-yan-wei-li-zhang-not-liang-for-yicheng-pilot already documents that Whyte, Wang & Cai's own citation chain to Yicheng never names Liang Zhongtang at all. Per the sourcing floor, a contested historical claim escalates to Tier 1-2; Qin & Wang (2017) clears that bar as a peer-reviewed journal article. It is independent testimony: the attribution to Liang is not footnoted to Liang's own interview (the paper's footnote 6, a 2012 Legal Weekly interview, is cited separately and only for Liang's own three stated reasons Yicheng was chosen) or to Wei & Zhang (2014) specifically — it appears as the paper's own stated background, treating Liang's authorship as settled within the demographic literature it surveys.

This does not answer whether Yan Wei & Li Zhang's own 2014 article names Liang — Qin & Wang cite that article only for the policy's operational rules (marriage age, birth-spacing interval), never in the same sentence as the authorship claim. It does establish that at least one other scholarly team studying Yicheng, writing independently of Liang's own self-presentation, treats his role as the proposer/architect as uncontested background fact rather than a disputed attribution.

Further leads

• Gu, B. and Wang, F. (2009), An experiment of eight million people (Beijing: Social Sciences Academic Press) — a Chinese-language book-length study of Yicheng cited by Qin & Wang (2017) alongside Wei & Zhang (2014) and Wu (2014) as one of three studies finding the two-child policy had little positive fertility impact; not checked for authorship attribution this session, Chinese-language and not located online.
• Wu, Y. (2014), "Preliminary analysis of a second-child experiment on 'later marry, later birth and longer interval' in Yicheng county," Population Journal 4: 103–112 — another study Qin & Wang cite for Yicheng's enforcement record; same access gap.
• Jiao, H. (2012-08-21), "Interview: Liang Zhongtang, a Family Planning Expert and Demographer," Legal Weekly — cited by Qin & Wang (2017) as the source for Liang's own stated reasons Yicheng was selected (rural population, railroad access, local welcome); URL given in Qin & Wang's footnote 6 (legalweekly.cn) was not independently checked this session.
• Qin & Wang (2017) cite Liang, Z. (2014a) Studies on China's Fertility Policies (Taiyuan: Shanxi People's Press) and Liang, Z. (2014b) China Population Problem (Beijing: China Development Press) as Liang's own book-length sources — distinct titles from the 2014 essay already tracked elsewhere in this vault cluster (see claim-liang-2014-book-most-discussed-content-is-ma-yinchu-not-song-jian and related notes); worth checking whether these titles match or differ from what that cluster already has on file.
• Scharping, Thomas, Birth Control in China 1949–2000, and White, Tyrene, China's Longest Campaign — both named in the open question's candidate next moves; this session found no accessible full text or excerpt discussing Yicheng or Liang for either book, so both remain untried in substance, not just in name.

Entity candidates

• Liang Zhongtang — person — the figure the whole dispute is about; already has entity-liang-zhongtang on file, but this capture adds a second, independent scholarly source (Qin & Wang 2017) crediting his role, worth folding into that entity note.
• Yu Qin — person — co-author of the Tier-1 source this capture rests on (National University of Singapore, Dept. of Real Estate); no existing vault presence.
• Fei Wang — person — co-author of the same Tier-1 source (Renmin University of China, corresponding author); no existing vault presence.
• Yan Wei — person — co-author of the still-unread 2014 China Journal article at the center of the open question; flagged repeatedly across this cluster's notes but the underlying document itself has never been read.
• Li Zhang — person — co-author of the same still-unread article; same status as Yan Wei.
• The China Journal — concept/venue — the paywalled journal hosting both Whyte-Wang-Cai (2015) and Wei & Zhang (2014); every note in this cluster traces back to what this single venue has published, and only one of its two relevant articles has actually been read.
